Limits
This page lists the fixed limits in FlutterFlow, grouped by where you meet them.
Prompts, messages, and attachments
The following table lists the limits on prompts, messages, and attached files.
| Limit | Value |
|---|---|
| Prompt length | 12 to 8,000 characters |
| Message length | 32,000 characters. If you send another message while one of yours waits in the queue, FlutterFlow combines them into one message, and the limit applies to their combined length. |
| Files per prompt or message | Up to 6 files, 4 MB in total |
| Image files | PNG, JPEG, WebP, and GIF. FlutterFlow resizes larger images to 1,568 pixels on the long edge before it sends them, and sends GIF files up to 4 MB unchanged. |
| Document files | PDF, DOCX, XLSX, PPTX, ODT, ODS, ODP, RTF, TXT, LOG, RST, TEX, CSV, TSV, MD, JSON, JSONL, YAML, XML, and HTML |
| Font files | TTF and OTF |
| Unsupported files | Any other type, such as SVG, audio, video, and ZIP files |
| Files bundled with your app | Up to 30 MB across all bundled files. The agent can’t bundle a file that would take the total over this limit. |
| Thread name length | 120 characters |
First version
The following table lists the limits on the first version of an app.
| Limit | Value |
|---|---|
| Screens | Up to 8 |
Threads and pushes
The following table lists the limits on threads and pushes. Your plan doesn’t limit how many threads the agent works in at once.
| Limit | Value |
|---|---|
| Pushes at the same time | 1 for each app |
| Threads in the thread list | The 50 most recently updated |
| Approvals for actions in connected services | Each approval request expires after 1 hour. Up to 10 requests can wait in one thread. |
Backend
The following table lists the limits on what each app’s backend stores.
| Limit | Value |
|---|---|
| Tables | 100 for each app |
| Fields | 100 for each table |
| File folders | 20 for each app |
| Profile fields | 30 for each app |
| Claims | 32 for each app |
| Record size | 1,000,000 bytes for each record, counting every field at its maximum allowed size |
| File size | Set for each folder. Owners and developers can see it under Largest file in Backend › Files › Rules, and ask the agent to change it. |
| Secret names | Up to 64 characters: uppercase letters, numbers, and underscores, starting with a letter. Names can’t start with a prefix that FlutterFlow reserves. |
| Secret values | 256 KB |
Your app’s backend can have usage limits, such as on Database reads and Database writes. Check your current usage in Backend › Usage.
For more about backend usage, see Backend usage.
Sign-in
The following table lists the sign-in limits for the people who use your app. Owners and developers can see the first four limits in Backend › People › Sign-in under Accounts and sessions, and ask the agent to change them. The password reset link’s lifetime is fixed. Shortest password appears only when email and password sign-in is turned on. For what each role can do, see Team roles.

| Limit | Value |
|---|---|
| Symbols drawn | 5 draws per app per day in Coordinated Universal Time (UTC). Failed draws don’t count. |
| Letters | Up to 8 characters supported by the icon’s fonts. When Letters is empty, the icon uses your app’s initial if its name has one. |
| Your own PNG | A PNG file of exactly 1,024 by 1,024 pixels, up to 1 MB |
Connections
The following table lists the limits on connecting and calling external services.
| Limit | Value |
