Three steps, then never again

One embed for you. A connect button for your customers. Integrations stop being your team’s problem.

01 · You, once

Embed the connect UI

App.tsx
import { FastnConnectCard } from '@fastn-ai/embed/react';

export function Integrations() {
  return (
    <FastnConnectCard
      orgId={org.id}
      token={token}
      onConnected={(e) => {}}
    />
  );
}
02 · Your customers, self-serve

They connect their stack

Embed it once.Integration becomes configuration.

fastn handles the plumbing (auth, mapping, retries, monitoring) so your customers just connect what they need and it works.

01

Every integration, already done

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.

02

Say yes in the sales call

One embed lights up the whole connector catalog. “Do you support X?” stops being a roadmap conversation and becomes a toggle.

03

Let agents act without losing sleep

Your AI agents get permission-scoped, audited access to every connected system. Every call logged, bounded, and reversible.

04

Live the same day

What took weeks of custom build ships in hours. The integration backlog stops existing as a category of work.

05

Engineers back on product

After the one-time embed, build and maintenance trend to zero. Teams that want deeper control can still drop into code.

06

Pass security review calmly

SOC 2, granular RBAC, private networking, full observability, self-hosting. Built for systems your customers can’t afford to get wrong.


Connection health,surfaced per customer.

Per-connection health, logs, and alerts inside your product. Integration stops being a black box.

Describe the integration. We’ll wire it.

The same prompt surface your customers get inside your product, ask for a system, a workflow, or an agent tool, and fastn assembles the connection.


You shouldn’t have to choosebetween rigid and opaque.

Most integration layers make you trade a schema you can’t bend for a black box you can’t explain. fastn refuses the trade.

The rigid option

A fixed, unified schema

Your customer’s custom fields and objects don’t fit, so every edge case falls back on your team.

Custom objects don’t map
Edge cases become support tickets
Every exception needs engineering
The opaque option

A flexible black box

It works until it doesn’t, and then you can’t see why or explain it to your customer.

No visibility into a failing sync
Nothing to show the customer
Debugging means filing a ticket
fastn: public and configurable

A documented, public surface

It still shapes to your product and to each customer’s fields and workflow. No forks, no black box.

Per-customer field and object mapping
Readable logs and traces, per connection
Drop into code whenever you want to

The same bottleneck, three desks

Whoever you are,this is your bottleneck

For revenue teams

Stop losing deals to a missing integration

“Do you integrate with X?” becomes “yes”, every time. Close the deals that used to die in security and stack review.

For customer success

Deliver what sales promised

Customers go live with the integrations they were sold, in days not quarters. Integrated customers stay, and churn drops by half.

For engineering

Get your roadmap back

One embed replaces the entire connector backlog. Your team ships product while customers configure their own integrations.
