CrabTalk vs Nango.
Managed auth, tools + data sync
Nango manages app connections, ready-made tools and synchronization through APIs and MCP. CrabTalk provides reusable service deployments with their own SQLite state and explicit resource budgets for tool calls.
Which fits your work?
CrabTalk
- Custom SQL operations shared by several agents
- Small, independently budgeted tool calls
- Private service copies with separate credentials and records
Nango
- Managed OAuth across connected business apps
- Ready-made tools and authenticated API proxying
- Integration syncs, triggers and connection lifecycle
Use both.
Use Nango to connect business accounts and retrieve app data. An agent can call a separate CrabTalk service to keep a shared review log or apply custom SQL rules without replacing the integration layer.
Capabilities side by side.
| Capability | CrabTalk | Nango |
|---|---|---|
| Existing integrations | Call accessible services or deploy available templates | Ready-made tools, triggers and sync templates |
| MCP | Hosted discovery and calling across service deployments | One endpoint with scoped tools and connected accounts |
| Provider credentials | Deployment credentials sent by the host to declared destinations | Managed user connections and automatic token refresh |
| Persistent data | Service-owned SQLite tables and queries | Integration sync records and connected app data |
| Custom behavior | Rust/Wasm tools with SQL and HTTP host APIs | Custom tools, syncs and authenticated proxy requests |
| Memory budget | 1–128 MiB per tool; lower one call in code | Platform compute metered across integration execution |
| Sharing | Shared deployment or independent template copy | Connections scoped to application users and agent sessions |
Review CRM changes across two agents.
An agent reads account changes and another reviews the decision history. Keep existing CRM records authoritative unless a separate service needs to own distinct data.
CrabTalk
- Check service coverage for the required CRM operations
- Add SQL tools for custom review records
- Connect both agents to the shared deployment
Nango
- Connect the CRM account through Nango
- Use existing tools or configure the integration sync
- Keep review status in the app or a separate custom tool
CrabTalk vs Nango pricing.
CrabTalk
Service owners pay runs, CPU, reserved memory-time and database rows. A published tool may charge callers separately; upstream provider usage is additional.
Nango
Nango meters authorized connections, integration compute time and data transfer, with plan limits or credits. Sync and webhook work contribute alongside interactive tool calls.
Count the connected accounts, background synchronization and completed app operations. Nango is outside the hosting calculator; its managed integration cost is broader than one function invocation.
Limits that affect the choice.
- CrabTalk’s deployment credentials and Nango’s managed end-user connections are different models. Include customer onboarding and token lifecycle in the decision.
- Nango supports custom tools and persistent integration sync data. Compare ownership and query needs instead of treating all state as exclusive to CrabTalk.
- CrabTalk tool budgets stop at 100 ms CPU and 128 MiB memory. Large synchronization jobs or dependency-heavy transformations need another execution path.
Questions about CrabTalk and Nango.
Does Nango already provide MCP tools?
Yes. Nango exposes ready-made and custom tools through agent sessions, with scoped connected accounts. CrabTalk’s distinction is its deployable service, SQL state and per-call resource model.
Must I write every integration on CrabTalk?
No. Call an accessible deployment or deploy an available template. Add missing operations only after checking actual service coverage and provider requirements.
Does a shared SQL service replace integration syncing?
Not by itself. A sync handles upstream changes, pagination and connection lifecycle. A CrabTalk service can own separate business records while Nango retains that integration work.
