Fair-use limits
Kommio Cloud is free for every team: no seat pricing, no plan tiers, every feature and every channel. Today no workspace is capped: the only limits enforced are the request rates and the file rules below. The reference levels are where we would talk to you, so one workspace cannot degrade the service for the others; they sit well above what a support team uses. Last updated 3 October 2026.
Enforced today
| What | Limit | Note |
|---|---|---|
| Agents, administrators, inboxes and channels | Unlimited | No seat pricing. Above 100 members we ask you to tell us so we can plan capacity. |
| Attachment size | 25 MB per file | Executables are refused; images are served inline, everything else as a download. |
| API and widget requests | See the API table below | Recover on their own within the minute. |
| Sign-up attempts | 5 an hour and 20 a day per network address | Disposable email domains are refused, to keep spam workspaces out. |
| Data retention | Conversations kept as long as the workspace exists | Events, audit trail, notifications, visitor context, the chat sessions of signed-in visitors who never wrote (30 days by default) and files marked as identity documents follow the retention settings you choose, with floors for security data. |
Reference levels per workspace
These are not enforced on Kommio Cloud today. They are the levels the product can apply per workspace, and the ones at which we would get in touch. If we ever switch them on, we will write to the administrators of every workspace near a level before it takes effect.
| What | Reference level | Note |
|---|---|---|
| New conversations | 50,000 per month | Inbound and outbound together. |
| Replies | 500,000 per month | Messages your team sends; what customers send never counts. |
| Outbound replies | 20,000 per day | Email goes through your own mailbox (SMTP), so your provider's limits also apply. |
| Contacts | 1,000,000 | Merged contacts count once. |
| File storage | 20 GB per workspace | Uploaded files and attachments together. |
| Webhook deliveries | 100,000 per day | Retried for a day; every attempt is in the ledger. |
| Apps and plugins | 25 installed apps | Hook calls time out at 5 seconds; failures never block you unless the app asked to be required. |
Even at a level, only what your workspace starts would wait: customers' inbound messages, automations, bots and flows are never refused.
API
| What | Limit |
|---|---|
| Requests per API key | 600 per minute |
| Requests per workspace | 3,000 per minute |
| Unauthenticated endpoints (sign-in, widget, public) | 300 per minute per IP address |
Requests above a limit get a 429 with Retry-After and X-RateLimit-* headers; nothing is dropped silently.
What happens when you reach a limit
- Rate limits (the API table) apply immediately and recover on their own within the minute.
- A reference level is a conversation, not a cut-off: we write to the workspace administrators first and agree a plan, which most of the time means raising the level for you.
- Abusive use is the exception: unsolicited email, unlawful content, or attempts to reach other workspaces lead to suspension, as the terms describe.
Your data, always
You can export conversations, contacts and settings through the API at any time, and the self-hosted edition runs the same product on your own infrastructure when you prefer that. Questions about a limit go to [email protected].
