CrabTalk vs PocketBase.
Self-hosted SQLite backend
PocketBase bundles SQLite, record APIs, authentication, realtime subscriptions and an admin interface in a portable backend. CrabTalk hosts Rust/Wasm tool services whose SQLite state and call budgets belong to each deployment.
Which fits your work?
CrabTalk
- A hosted SQL tool service shared across agents
- Small per-call memory and CPU budgets
- Service templates deployed with independent state
PocketBase
- A portable backend you operate yourself
- Built-in auth, record APIs and an admin interface
- Go or JavaScript hooks around application data
Use both.
A PocketBase application can keep its users and records while a separate CrabTalk service supplies reusable integration tools. Server-side code can call those tools over HTTP without moving the application database.
Capabilities side by side.
| Capability | CrabTalk | PocketBase |
|---|---|---|
| Database | SQLite per service deployment | Embedded SQLite in the PocketBase backend |
| Default interface | Explicit JSON tools through MCP, HTTP and CLI | Record APIs, client SDKs and an admin dashboard |
| Custom logic | Rust/Wasm tools with SQL and host APIs | Extend with Go or JavaScript hooks and routes |
| Client features | Call service tools for results | Built-in auth, file handling and realtime subscriptions |
| Memory scope | 1–128 MiB reservation per tool call | Memory of the backend process on your host |
| Operations | Service deploys and database migrations managed by the host | Operate the executable, data directory, backups and upgrades |
| Reuse | Shared deployment or private template copy | Portable application and data deployed to your server |
Keep a team task list accessible to agents.
People and agents update tasks and read the latest status. A ready-made record interface may cover the operation without custom endpoint code.
CrabTalk
- Define task tools and SQLite migrations
- Set access and execution budgets
- Connect the agents to the deployed service
PocketBase
- Create task collections and access rules
- Use the record API and existing client features
- Add hooks or routes only for missing business logic
CrabTalk vs PocketBase pricing.
CrabTalk
Service owners pay runs, CPU, reserved memory-time and database rows. Shared tools may separately charge callers a published per-call price.
PocketBase
For a self-hosted PocketBase deployment, budget the server, persistent storage, backups and supporting services such as email. Your chosen host determines infrastructure charges.
Compare the complete hosted service with the complete self-hosted setup, including idle capacity and operational work. PocketBase is outside the execution calculator.
Limits that affect the choice.
- Both use SQLite. The main choice includes hosting ownership, client features and the interface around the database.
- PocketBase’s documentation warns that pre-1.0 compatibility is not guaranteed and advises care for production-critical applications. Check the current release and migration guidance.
- CrabTalk tool budgets stop at 100 ms CPU and 128 MiB memory. It does not provide PocketBase’s admin UI, authentication system or realtime client interface.
Questions about CrabTalk and PocketBase.
Does PocketBase already provide persistent SQL data?
Yes. SQLite is part of the backend, alongside record APIs and realtime subscriptions. CrabTalk’s difference is the hosted tool-service boundary and per-call resource model.
Do I need custom code for ordinary PocketBase CRUD?
No. Collections and API rules provide a record interface. Use that directly when it covers the task; add hooks or routes for additional behavior.
Can I deploy the PocketBase executable to CrabTalk?
No. CrabTalk runs Rust/Wasm service tools, not arbitrary server binaries. Porting also needs to account for auth, files, subscriptions and existing clients.
