One embed for you. A connect button for your customers. Integrations stop being your team's problem.
import { Fastn } from "@fastn/ucl" <Fastn.Connect tenant={customer.id} />
fastn handles the plumbing (auth, mapping, retries, monitoring) so your customers just connect what they need and it works.
Your customers authorize the systems they run inside your product in minutes, including the bespoke integrations pre-built catalogs break on. Integration becomes configuration, with zero code per customer.
One embed lights up the whole connector catalog. "Do you support X?" stops being a roadmap conversation and becomes a toggle.
Your AI agents get permission-scoped, audited access to every connected system. Every call logged, bounded, and reversible.
What took weeks of custom build ships in hours. The integration backlog stops existing as a category of work.
After the one-time embed, build and maintenance trend to zero. Teams that want deeper control can still drop into code.
SOC 2, granular RBAC, private networking, full observability, self-hosting. Built for systems your customers can't afford to get wrong.
Per-connection health, logs, and alerts inside your product. Integration stops being a black box.
A fixed, unified schema. Your customer's custom fields and objects don't fit, so every edge case falls back on your team.
A flexible black box. It works until it doesn't, and then you can't see why or explain it to your customer.
A documented, public surface that still shapes to your product and each customer's fields and workflow. No forks, no black box.
"Do you integrate with X?" becomes "yes", every time. Close the deals that used to die in security and stack review.
Customers go live with the integrations they were sold, in days not quarters. Integrated customers stay, and churn drops by half.
One embed replaces the entire connector backlog. Your team ships product while customers configure their own integrations.
Connect the systems your customers actually run on
Embed fastn once and let your customers and your agents connect anything they need. No infrastructure to run, no per-customer builds.
