A May 21, 2026 guide lays out a head‑to‑head comparison of the Zapier SDK and Nango for AI product teams that must read and write across customer stacks, framing the decision as a trade‑off between platform reach and credential custody. The guide centers on an engineering need for an integration layer that takes on auth, retries, rate limits and ongoing maintenance of upstream APIs. Teams will mainly weigh hosted convenience and immediate ecosystem access against self‑hosted control and compliance.
On product scope and coverage, the SDK exposes programmatic access to a library of more than 9,000 apps, plus authenticated HTTP access to roughly 3,000 additional services, surfaced through a TypeScript package with generated action signatures. Nango publishes 800+ managed APIs, uses AI‑generated connectors for off‑catalog endpoints, and is source‑available under the Elastic License. Deployment models differ: the SDK runs on managed infrastructure that stores tokens for you, while Nango can store credentials in its cloud or be self‑hosted inside a customer VPC.
The guide frames the two offerings as distinct architectures: a broader platform versus a focused integration layer. The SDK is embedded in a platform that includes Workflows, Tables, Forms and an agent surface called MCP, allowing actions invoked from code to feed directly into automation and agent tooling. By contrast, Nango is purpose‑built for auth, sync and API access and does not ship workflow orchestration, agent tooling or storage as part of its product.
Governance and security implications are central to the comparison. The managed platform handles OAuth flows, token refresh, rate‑limit management and multi‑tenant isolation, which reduces operational burden but means credentials live off‑premises. Nango’s self‑host option shifts credential custody and the operational responsibilities for rotation, auditability and incident blast radius to teams that require in‑house control or stricter compliance.
Developer experience is another axis of differentiation. The SDK delivers TypeScript types, compile‑time checks and editor autocomplete to catch bad field names and payload shapes before runtime, supporting safer calls from agents and automations. Nango emphasizes rapid connector generation: developers can describe an integration in natural language to produce integration code, a practical approach for APIs that lack prebuilt wrappers and for faster onboarding of new endpoints.
Pricing and rollout context will affect adoption. The SDK is free during open beta, offering early access to its ecosystem. Nango’s published plans include a free tier (10 connections, 100k proxy requests) and paid plans that start at $50/month (Starter) and scale to $500/month (Growth), with usage‑based metering across tiers. Ultimately, the choice depends on expected scale, regulatory needs and whether teams prioritize immediate ecosystem reach or tighter credential custody.
