Embedded integration platform that lets SaaS products offer customer-configurable integrations through one widget and unified API.
fastn is an embedded integration layer for B2B SaaS products. It lets a company embed a widget so its customers can connect and customize integrations with apps like Salesforce, HubSpot, Snowflake and NetSuite inside the product. The platform provides a unified API, versioned workflows, an MCP gateway for AI agent tool access, and integration agents that build and maintain mappings. It handles authentication, retries, monitoring and automated fixes. It is aimed at SaaS engineering and product teams that want to offer integrations without building each one. A free start and demo booking are offered.
