Fusebit
Fusebit was a code-first, developer-facing embedded integration platform (embedded iPaaS) founded in Seattle in 2019, letting SaaS teams build, deploy and run third-party integrations inside their own products using serverless functions, managed OAuth connectors and an embeddable browser IDE. The company was acquired and the platform is retired: as of 2026-09-10 the domain fusebit.io is still registered but publishes no DNS A record, so the API, the developer documentation, the management portal and the asset CDN all fail to resolve. What survives is substantial and first-party — two published OpenAPI 3.0 contracts covering 89 operations, four dated release-note streams served from Fusebit's own GitHub Pages, 101 npm packages under the @fusebit and @fusebit-int scopes, and 35 public repositories across the fusebit and fivequarters GitHub organizations. This profile is a historical record of a retired API, not a callable surface.
Fusebit publishes 18 APIs on the APIs.io network, including Accounts API, Boundaries API, Clients API, and 15 more. Tagged areas include Developer Tools, Embedded iPaaS, Integration, Serverless, and Authentication.
Fusebit’s developer surface includes changelog, authentication, CLI, and 20 more developer resources.
