Factorial Developer Portal

Describe the app.
AI builds it on Factorial.

Your AI agent writes, tests, and iterates real code on Factorial's fully managed runtime — wired into the API, secrets, and scheduling from the first prompt.
It runs in your developer harness today, and fully inside Factorial next. ✨

Tell us what you want to build — your agent and the platform take care of the rest.

An App is anything on top of Factorial

Not just integrations. Automations, reports, forms, notifications, scheduled jobs — describe it, and your agent can build it on the Factorial API.

Marketplace integrations

Two-way sync between Factorial and any external system — payroll, HR, or project tools.

Reports & exports

Generate CSV, XML, or PDF files from Factorial data — on demand or on a schedule.

Form-driven workflows

Embed a form, collect input, and run logic — setup flows, data entry, approvals.

Notifications

Send email or downstream updates when something changes in Factorial.

Scheduled jobs

Poll an API, reconcile data, or run housekeeping on any cadence.

API automations

Anything the Factorial API can do, wired together your way.

An agent that knows Factorial

Skills, SDKs, and a managed runtime make your AI agent fluent in Factorial from the first prompt — it does the building, the platform keeps it safe.

AI skills, set up for you

fcode clone installs the Factorial Code skills, so your AI agent knows the platform — processes, the API, forms — from the first prompt.

An MCP server for your agent

Expose your processes as tools and run agent-generated code in a secure sandbox, straight from Cursor, Claude, or any MCP client.

Skills with worked examples

The skills ship with real examples and references — custom-app and marketplace patterns your agent learns from, not a blank file.

Production-grade SDKs

Official JavaScript and Python SDKs the agent writes against, with pagination, OAuth, and error handling built in.

Full local workflow

The agent develops and tests on your workstation, then pushes to the cloud when it's ready.

Open-source foundation

See exactly what the agent builds on — and contribute back.

Coming soon

The agent, fully inside Factorial

Next, you'll describe what you need and watch the agent write, test, and iterate the code without leaving the dashboard — the same managed runtime, no local setup.

Everything agent-written code needs, out of the box

A managed, shared platform means agent-written code is safe by default — partners and internal teams never rebuild infrastructure. Each customer's runtime is isolated, observable, and billable on its own.

Scheduling

Run sync jobs on any cadence — no cron servers or cloud functions to operate.

Webhooks

Receive, validate, and route Factorial events with built-in retry handling.

Secrets management

API keys and credentials stored as encrypted variables.

Audit logs

Every execution tracked with full input and output history.

Errors & retries

Per-item status reporting and automatic retry policies.

Multi-tenant

One App, isolated per customer — shared logic, separate state.

Walk the red carpet

Seven steps from idea to a live App on the Factorial Marketplace — every one of them paved.

Get in & spin up an App

Request access once to join. Then create an App from the console — name it, pick JavaScript or Python — and its workspace is provisioned instantly, no approval.

Clone & meet your agent

fcode clone pulls the workspace local and sets up the AI skills, so your agent knows the platform from the very first prompt.

Build with AI

Your agent writes and iterates the logic from the skills' worked examples and your specs, on top of the Factorial SDKs.

Test

Run it locally, push to the cloud, and exercise it from a Factorial demo — OAuth handled for you, out of the box.

Request a release

Open a release; the team reviews and CI checks run automatically.

Live on the Marketplace

Promoted to production and listed on the Factorial Marketplace, ready for customers. 🎉
