Automate anything on a workflow canvas — on your own server.

W flow is a visual workflow builder in the spirit of n8n. Drag 445 nodes onto a canvas, connect them, and turn “when this happens, do that, then that” into automations — webhooks, cron schedules, AI agents, HTTP, Slack, email and more. Your API keys, your machine.

What you can build

Webhook endpoints

Turn any workflow into an API: receive HTTP calls, process the payload, answer the caller.

Cron scheduling

Schedule (cron) triggers fire workflows on their own — every hour, weekdays at 09:00, anything.

AI agents & pipelines

Chat models, agents with tools, embeddings, structured extraction — with keys you bring yourself.

244 integrations

Slack, Discord, Telegram, GitHub, Notion, Stripe, Google, Outlook, Gitea, Mastodon, Groq, Mistral, email (SMTP) and many more.

18 ready-made feeds

YouTube channels, subreddits, Hacker News, GitHub releases, Mastodon, Bluesky, podcasts, Google News — no API key needed.

Reusable sub-workflows

Call one of your workflows from another as a building block — build once, compose everywhere.

Private by design

Accounts, encrypted credentials and sessions live in the instance's own database — hosted in Germany, or on your own server with the self-hosted copy.

Self-hosted

One Node process serves everything — UI, REST API and webhooks. Data persists in a local folder (SQLite by default, PostgreSQL optional). Run it with npm start, Docker, or a VPS behind Cloudflare/Caddy. The admin panel lives on its own port with its own login, IP allow-listing and SQL console.
