Writ Documentation.

Overview

What Writ is, how the pieces fit together, and where to start reading.

Quickstart

Go from an empty workspace to a JSON response from your first endpoint.

Where it runs

Desktop, Writ Cloud or your own self-hosted fleet, and what changes between them.

Record a workflow

Record a browser session once, then replay it with typed inputs and extracted output.

Scribe

Ask in plain words: Scribe opens a real browser, builds monitors, workflows and crawls, and pauses for your approval.

Scribe and AI sessions

Describe the task in words and let Scribe drive a real browser to build or run it.

Step reference

Every step type a workflow can contain, with its inputs and its behaviour.

Personas, secrets and agents

Encrypted logins, TOTP, the vault, and which machine actually runs the browser.

Authentication

API keys, consumer keys, OAuth tokens, scopes, rotation and revocation.

REST API reference

Every endpoint of the Writ REST API, with its request and response shape.

SDKs

Official clients for Python, TypeScript, Go and Rust, plus plain HTTP.

Managed endpoints

Publish a workflow as a versioned REST endpoint with quotas and usage records.

Custom domains

Serve your published endpoints from your own hostname, with managed certificates.

Consumer keys

Hand scoped, revocable keys to the people and systems that call your endpoints.

MCP server

Expose your workflows as MCP tools, then connect Claude, Cursor or any MCP client.

OpenAI-compatible endpoint

Drive a live browser session from any OpenAI-compatible client, with streamed events.

Monitors

Watch a page or an endpoint and fire something the moment it changes.

Automations and webhooks

Schedules, triggers, inbound webhooks and signed outbound deliveries.

Crawl a whole site

Map a site, crawl it across your fleet, and save the crawl so it can be re-run or reused fresh.

Datasets, storage and files

Where run output lands, how to search across it, and how to pull files back out.

Writ Desktop

The app that records workflows and runs them on your own machine, with the engine bundled in.

Your own machines

Link a machine to Writ Cloud with a pairing code, then see and manage your fleet.

Self-hosting

Run the open-core coordinator yourself with Docker, connect an agent, and put it behind your own domain.

Uplink

Call a system that has no API and no public address: the agent runs inside your network on an outbound connection, behind one published endpoint.

Notification channels

Set up email, Slack, Discord, Telegram, SMS, WhatsApp, Signal, Pushover and webhooks, and choose what reaches you.

n8n, Zapier and Make

Call Writ from the automation tool you already run, over REST, OAuth or a signed webhook.

Marketplace

Install someone else’s automation and bind your own logins to it, or publish your own.

Account and team

Members, roles, invitations and single sign-on for your workspace.

Billing and usage

How cloud running time and AI tokens are metered, and how to keep spend predictable.
