Swytchcode vs. Nango
Nango is the integration layer for customer-facing product integrations: embedded OAuth, syncs, and unified APIs. Swytchcode is the execution layer for agents, running API calls with auth, retries, idempotency, and schema validation.
Bring your own LLM · MCP for integration context · CLI for governed execution
The verdict
Nango is the superior choice for customer-facing product integrations: embedding OAuth so your users connect their own accounts, running two-way data syncs, and building unified APIs in code you own. Swytchcode is the execution layer that runs an agent's API calls, best suited for teams that need reliable tool calling, with built-in auth, automatic retries and idempotency, and response schema validation that catches drift before it reaches production.

Feature by feature
Where the two layers differ
Primary use case
Nango is built for customer-facing product integrations: your users connect their external accounts through an embedded auth flow, and you sync or act on their data behind your product. Swytchcode is built for agents calling APIs: the execution layer for what an autonomous agent does in production.
Integration model
With Nango you write TypeScript functions (often AI-generated) that call provider APIs, run syncs, and process webhooks on managed infrastructure. Swytchcode routes calls through a policy manifest with auth, retries, idempotency, and schema validation built into the runtime, with no per-integration function code to maintain.
Language & integration surface
Nango centers on TypeScript functions consumed via API, SDK, or MCP. Swytchcode is language-agnostic: it runs as a CLI or MCP server, so any agent, IDE assistant, or script can call it directly.
Reliability & governance
Nango handles token refresh, rate-limit backoff, retries, and per-connection observability for product integrations. Swytchcode adds idempotency on writes and response schema validation at the call level, plus a policy manifest with allowlists and dry-run enforced deterministically at execution time.
When to choose Nango
Choose Nango when your core need is customer-facing product integrations: embedding OAuth so your users connect their own accounts, running two-way data syncs, building a unified API across providers, and owning the integration logic as reviewable TypeScript code.
When to choose Swytchcode
Choose Swytchcode when your agents need to call real APIs reliably in production. It is the execution layer for what your agent does: auth, retries, idempotency, schema validation, and policy, callable from any agent, CLI, or MCP client, without writing and maintaining per-integration functions. Swytchcode is strongest where the API is hardest: systems carrying years of versions, partial documentation, and undocumented sequences, where a model cannot reliably guess the right call. Modern, self-describing APIs are well served by several tools. Older enterprise systems are the case we built for.
