Monthly Active Users (MAU)

MAU is counted only when a user connects to a mesibo server (cloud or on-premise) within a monthly billing cycle, a message is received for the user or any API operation is carried out on the user. To further clarify, it will be only counted as one even for multiple operations within a monthly billing cycle.

$0.01 per MAU

Concurrent Users (simultaneous connections)

The concurrent user limit will be 10% of the MAU. In our experience, simultaneous users are generally less than 5% of MAU and hence you are unlikely to cross that limit. However, in case you cross the 10% limit, it will be compensated by billing you for MAU = ( concurrent users X 10).

There is NO limit on concurrent users when you host mesibo on-premise.

Unlimited
10% of MAU

Real-time Bandwidth

Real-time bandwidth consumed by your apps within a monthly billing cycle. Real-time bandwidth includes the bandwidth used by client connections, messaging, backend API invocations, webhooks, push-notifications, etc. However, media bandwidth used by Video and voice calls or conferences does not count towards the real-time bandwidth.

There are no real-time bandwidth charges when you host mesibo on-premise.

Free
$0.9 per GB

Real-time Database

Maximum Real-time storage used by your apps within a monthly billing cycle. Real-time storage includes everything stored by your app including messages, users, groups, etc.

There are no real-time database charges when you host mesibo on-premise.

Free
$2.5 per GB

Video and Voice Calling

One-to-one video and voice calling are free and unlimited. There are absolutely no charges for one-to-one video and voice media bandwidth. However, each call exchanges a few messages (typically 5 to 8) every few seconds, to set up and to keep calls alive, which counts toward the real-time bandwidth. The bandwidth consumed by these messages is minimal and very small.

Free

Video and Voice Conferencing

Mesibo only charges for the bandwidth consumed by all your participants. There is no limit on the number of participants. Conferencing Bandwidth depends on the number of participants and video resolution used. Refer to the conferencing page for details.

Free
$1 per GB

TURN Server

TURN servers dramatically increase the reliability of video and voice calling, especially when your users are behind firewalls, or non-cooperative routers, or symmetric NAT. The use of TURN server is highly recommended and it's ON for your apps by default. You can disable it from the mesibo console if requires.

$0.4 per GB

Scripting & Chatbots

Scripting and Chatbots are charged by the script execution duration. The duration is calculated from the time your script begins executing until it returns or otherwise terminates, rounded up to the nearest 1 ms.

There are no scripting and chatbot charges when you host mesibo on-premise.

Free
$0.01 per sec of CPU duration

Message Retention

All your messages are retained indefinitely till your account is active.

Unlimited

File Transfer Size

mesibo allows you to use your own file servers or cloud services like Amazon AWS, Amazon S3, Google Cloud Storage, Microsoft Azure, etc. for file storage. Hence, mesibo has no restrictions on file size.

Note: Calculation does not reflect protocol overheads.

How will you be Billed?

Assume that your application has 1,000 monthly active users (MAU) and sends 20 million messages of average 50 bytes (utilizing about 1 GB bandwidth). Let's calculate what will be the monthly cost for On-premise and Cloud deployment.

The total cost for 1,000 MAU will be 1,000*0.01=$10 per month.

- For On-premise deployment, there are no other charges, and hence, the total cost will be only $10 per month as calculated above.

- For Cloud deployment, there will be an additional cost for bandwidth and storage. In this case, 1GB bandwidth. Hence, the total cost will be $10+1*0.9=$10.9 per month. Also, concurrent users are limited to 10% of MAU. So in this case, 1,000/10 = 100 concurrent users will be allowed. If you exceed that, say 150 concurrent users, you will be charged for 150*10 = 1,500 MAU.

You can view your live usage in mesibo console. Use the Pricing Calculator to get an estimate for your usage.

To know more about MAU, concurrent users, message bandwidth and storage, Refer to Notes and FAQs below.


 

Pricing Notes

Free Trial

You can get started with mesibo and use it for free. Upon sign-up, your account will be added with sufficient free credits to get you started and use the service. You can use these free credits for testing and development without paying a single penny until credits validity expires, and you wish to switch to Pay-As-You-Go (PAYG) plan.

Pay-As-You-Go (PAYG) Plan

You can switch to PAYG plan anytime by adding the credit balance in your account.

PAYG Credits

You can add a PAYG credit balance as low as US$ 50 to your account whenever you need to. Your usage charges will be deducted as it happens. You can use credits till it lasts or expires. You can check your credit balance and validity in ‘My Account’ section of the console.

Limits, Quotas, and Constraints

mesibo offers free quota for both free and PAYG subscription. If you exceed these limits, add credit to your account to prevent any interruption of service. We calculate quota as defined below:

  • MAU

    MAU is counted only when a user connects to a mesibo server (cloud or on-premise) within a monthly billing cycle, sends a message or a message is received for the user, or any real-time or backend API operations are performed on the user, for example, create, edit, group membership, etc. In the case of on-premise, all messages and real-time API operations are performed through your server and hence not charged for. To further clarify, it will be only counted as one even for multiple operations within a monthly billing cycle.

  • Concurrent Users (or peak connections or simultaneous connection)

    There is no limit on concurrent users in an on-premise deployment. In Cloud deployment, the concurrent user limit will be 10% of the MAU. In our experience, simultaneous users are generally less than 5% of MAU and hence you are unlikely to cross that limit. However, in case you cross the 10% limit, it will be compensated by billing you for MAU = ( concurrent users X 10).

  • Total Users

    There is no limit on the total number of users you can create. Since we do not charge for the total users, an app can misuse and load the system by creating unlimited users without any active users. Hence to avoid misuse and to ensure fair usage, we require that your monthly active users (MAU) should be at least 5% of the total users, if not more. If your MAU are less than 5%, MAU will be counted at least (total users x 5)/100.

  • Total Groups

    There is no limit on the total number of groups you can create. However, for the cloud deployment, the number of groups should not exceed four times the monthly active users (MAU). This is a practical and generous limit only to prevent misuse by any app creating unlimited groups without any active users (generally an app shouldn't require more groups than the active users). In case, the total groups exceed 4 times the MAU, the MAU will be counted at least (total groups / 4). There is no such limit on on-premise deployment.

  • Messages

    A message is the unit of data that is sent between two users or multiple users in the case of a group message. Messages are charged by the size of messages (refer below).

    • Message Delivery and Storage

      mesibo uses cut-through switching to deliver your messages in real-time with minimum latency. However, if the destination is not online, mesibo stores the messages till the user is online. If you decide not to save the messages in the database, you can do so by setting a flag while sending messages using Real-time APIs.

    • Message Retention

      mesibo offers an unlimited message retention period, only limited by the storage quota and usage. You can anytime clear storage from the mesibo console or by using Backend APIs.

    • Message Charges

      Instead of message count, mesibo charges for offline messages stored in the database, and the total outbound network traffic at the session layer (layer 5) of the OSI model to deliver messages to your connected/online users. The network traffic includes payload, as well as protocol & encryption overheads (refer below). Note that, mesibo absorbs traffic due to TCP/IP overheads and does not charge you for that. You can view statistics of your traffic and storage usage in mesibo console.

    • Protocol and Encryption overheads
      • Protocol overhead:

        Some additional traffic between the server and clients is necessary to establish and maintain a connection. Depending on the choice of API (client or server-side), this traffic might include mesibo protocol overhead, or HTTPS header overhead. Each time a connection is established, this overhead, combined with any SSL encryption overhead, contributes to the connection costs. This shouldn't contribute a lot to overall traffic, however it can be a substantial if your client connects frequently for the short duration.

      • SSL encryption overhead:

        There is an overhead associated with the secure encrypted connection (TLS). On an average, this cost is approximately 3.5KB to 6KB for the initial handshake, and approximately tens of bytes for TLS record headers plus padding on each outgoing message. For most apps, this is a small percentage of your traffic. However, it can grow large if your client makes frequent encrypted connections for a short duration. You can selectively enable (default) or disable secure encrypted connection using client side API.

  • Real-time Connection

    A rea-ltime connection is counted every time when your client connects to mesibo server. Your client may connect multiple times in a day because of the way mobile operating systems work. When the screen goes OFF on your mobile device, Android and iOS usually move apps to sleep state within some duration and then disconnect all the network connections to conserve system resources and battery life. Hence, apps will need to reconnect when they come out of the sleep state. While mesibo client API takes care of reconnection and your app doesn't have to do anything extra, it is worth knowing why it happens and protocol/encryption overheads associated with it.

  • Audio/Video calling

    Audio and Video calling minutes are unlimited in both free and paid plans. Typically, 5 to 8 messages are exchanged to setup or re-connect a voice or a video call. In addition to that, minimal messages are exchanged from each end every few seconds to keep call alive, exchange quality and control information etc. The bandwidth consumed by those messages will be counted in your billing (approx ~50 Kbytes). There are no other charges for the duration of the call or the bandwidth unless you use our TURN (relay) service.

  • File Transfer, Cloud storage & File size

    mesibo allows you to use your own file servers or cloud services like Amazon AWS, Amazon S3, Google Cloud Storage, Microsoft Azure, etc. for file storage. Hence, mesibo has no restriction on file size. You can send files of unlimited size using mesibo. Also, unlike other services which charge premium for secure/encrypted file transfer, mesibo allows you to encrypt each and every message without any additional charges.

  • TURN (relay)

    You can add TURN (relay) to add reliability to calls by assisting some users that are behind badly behaving OR symmetric firewalls (roughly less than 5% of users).

  • Backend API Invocations

    Each backend API invocation is counted when your server sends a backend API request to the mesibo server. There is absolutely no limit on the number of backend API invocations or any kind of rate limit when invoked for creating new users, new groups, and adding new members, subject to your account balance and validity. However, for any other operations, the number of monthly invocations should not exceed ten times the number of monthly active users (MAU). This is a practical and generous limit only to prevent misuse by any app sending unlimited requests (for example, to keep getting tokens from backend APIs instead of saving them locally). In such case, the total invocations exceeding 10 times the MAU, the MAU will be counted at least (total invocations / 10). This limit does not apply to on-premise deployment for group and messaging operations. Also, there are charges for monthly up to 1000 invocations for free accounts and 10,000 invocations for paid accounts, irrespective of MAU.

Charges & Billing Cycle

Your account will be charged at the Pay-As-You-Go rates described in the pricing table above. The usage charges start from the billing date and consist of charges for all the chargeable resources consumed in a calendar month. All the pricing and charges are in US dollars ($).

Cancellation Policy

You may cancel this PAYG subscription at any time by stop using it. There is no refund of the credit balance.

Pricing FAQ

Q: How much does the mesibo costs?

Mesibo is free to start. Mesibo gives you free Credits worth $50 on sign-up which is valid for 30 days. After that, Mesibo offers you Pay as you go pricing for both its On-Premise and Cloud offerings. That means you only pay for the services you consume, and once you stop using them, there are no charges or termination fees. Refer to the Mesibo pricing page to know more about pricing.

Q: Is there any agreement that we have to sign to use mesibo?

There is a Master Service Agreement / Terms document available which is applicable to all the mesibo users. You or mesibo will not require to sign (e-sign or physically), accept, or otherwise agree to any other documentation to use mesibo services.

Q: What are the limits on free tier usage?

The free tier/credits are offered for evaluation only and hence there are fair usage limits.

  • Free credits MUST be used for development only and not for commercial usage.
  • To avoid abuse, free credits are spread across the evaluation period and hence there are limits on daily usage.
  • There are limits on the number of users, groups, group members, and group call duration. However, these limits are reasonable and will not hamper you from evaluating any of the mesibo features.

Q: What is 'Monthly Active Users' (MAU)?

Monthly Active User (MAU) represents the unique monthly active users for a monthly billing cycle.

MAU is counted only when a user connects to a mesibo server (cloud or on-premise) within a monthly billing cycle, sends a message or a message is received for the user, or any real-time or backend API operations are performed on the user, for example, create, edit, group membership, etc. In the case of on-premise, all messages and real-time API operations are performed through your server and hence not charged for. To further clarify, it will be only counted as one even for multiple operations within a monthly billing cycle.

Q: What is Concurrent Users (peak connections/simultaneous connection)?

Concurrent Users is a metric of the maximum users connected to the mesibo server at the same time at any given moment. Typically, CU is 10% of daily active users (DAU) which is typically 50% of MAU. However, these metrics vary between apps depending on the nature of the app. Calculating and watching CU will help you determine the right mesibo plan for your app today and in the future.

Concurrent users are also referred to as peak or simultaneous connections.

Q: What is Message Rate Limit?

Message rate limit (throttling) is referred to as a total number of messages that can be sent by all your users in any given second. Typically, a message rate/second for an application like WhatsApp is 0.05% of MAU (based on public stats). mesibo assigned much higher rate limit than that so you should encounter rate limit only in rare circumstances.

Q: Do Voice and Video call quality differ in FREE and PAYG Plan?

Absolutely not - quality remains the same whether you are in free or a premium plan.

Q: I will be using TURN servers. How much the TURN server cost for a 60-minutes call?

The mesibo charges only for the TURN bandwidth and not per-minute usage. The reason is that the TURN server is only active for a short duration, and hence it is not fair to charge for the entire call duration. Generally, the TURN server is active during the call initialization and then becomes inactive once the peer-to-peer connection is established. Hence, you will only be charged for bandwidth consumed during the active duration. The active duration can be longer if the participants are behind no-cooperative NATs/firewalls or can be a fraction of the total duration (say 30 seconds for a 60-minute call).

The bandwidth consumption depends upon the call quality and the active duration. Typically an HD (720p) call for 100 minutes will consume around 1 GB of bandwidth per participant. A non-HD call for 250 minutes consumes around 1GB per participant. Hence, depending on your call quality and TURN active duration, you can estimate the TURN bandwidth and the cost. You can use the mesibo console to monitor TURN usage and charges.

Q: Is there any limitation on the number of applications, users, or groups? What happens if I exceed the limitations?

There are no limitations once you are a paid user. However, mesibo has intelligent algorithms to detect unfair usage and abuse patterns and in such conditions, requests from your users may be throttled.

The free trial has a limitation on the number of users and groups.

Q: Are there any feature differences between the PAYG and FREE plan?

No, all the features are available in all the plans.

Q: What happens if my apps exceed the credits?

We usually do not throttle your app immediately, unless in extreme situations. We will send you an email and also inform your backend using the webhook when your app usage exceeds available credits. We will throttle or temporarily disable your app only if you do not take any action in 24 hours even after these notifications. We will further wait for 7 more days before we delete your data.

Q: How do I know how much I am spending?

The Mesibo console is the best way to keep a tab on your usage and charges. The Mesibo console is updated at regular intervals with the usage and corresponding charges.

Q: How do I know which pricing plan is right for me?

You are free to use Mesibo APIs and Services, within free tier limits for testing and development. Our demo apps and source code is an ideal testing ground for you to evaluate what Mesibo can do for you. You can move to the PAYG plan once your evaluation completes or the free tier limit expires, whichever is early.

Q: Do I need to change my app if I move from free to PAYG plan?

Absolutely not! There are zero changes to the way you deploy your application or use our APIs irrespective of you are using our free or PAYG plan.

Q: What kind of support do you receive in PAYG vs Free plan?

We have 24-hour support and monitoring available from our Singapore and United States offices. For any queries, you can contact us via email at support@mesibo.com.

Q: Do you offer Educational discounts?

Yes, refer to the next question.

Q: How to avail of free offer for students, educational institutes and non-profit organizations?

mesibo is completely free for educational and research institutes, students, non-profit organizations, or other non-commercial apps for a good cause.

To avail of this offer, your app must be completely non-commercial (no charges, no ads), must not use other commercial paid services, and must attribute mesibo for the mesibo services your app is using on all the key screens.

Once your app is ready and live on respective app stores, send us a link to review. If all good, we will mark your app for free usage.

Q: How long are mesibo credits valid?

The credit validity varies from 90 days to 1 year depending on the payment amount. You will see the exact validity on the payment screen when you initiate a payment and also in your invoice. You can also check validity in Mesibo Console, under “My Account -> Payment History”. Your unused credits do not carry forward and they will be invalid after the validity period.

Q: What Payment Methods do you accept?

Our payment service provider accepts credit cards and GPay. We also accept Wire Transfers to our bank in Singapore for the larger payment (you need to be an existing paid user for making wire transfers).

Q: Can you extend the validity of my mesibo credits?

When you buy credits, we allocate system resources for you to ensure that you have the highest level of service experience using mesibo. Since we have already allocated resources for you, we are unable to extend the validity of your credits. If you require longer validity, we recommend buying credits for a larger amount which gives you the longest duration of validity.

Q: How do I get invoices or receipts for my payments?

Mesibo sends a payment receipt after receiving each of your payments.

  • If you make a payment via wire transfer, the payment receipt will have the amount received, the name of your company (as provided by you), address (as provided by you), mesibo account email address, and mesibo account ID.
  • For credit card payments, it will have the amount received, mesibo account email address, and mesibo account ID.
  • We do not generate invoices or send any other documents.

Additionally, all your payment information is available in Mesibo Console, under “My Account -> Payment History” with the payment date and the amount. You can take a print if you need it for your records. We do not provide any additional invoices.
