What it really is

Writebook — free self-hosted web app for publishing books online, by 37signals.

Our take

Writebook is a lightweight, self-hosted publishing platform from 37signals (Basecamp, HEY) that lets anyone turn text and images into a clean, browsable online book — completely free. The DB misidentifies it as an AI content-writing tool for manuscript planning; it has no AI features and no manuscript outlining. It is also miscategorized as 'Freemium' — the software is 100% free with full source code included, though you supply your own server. Think of it as a private, self-controlled alternative to Medium or GitBook for long-form content.

Why we rate it

Rare combination of zero cost, clean UX, and genuine data ownership. 37signals' track record means it's well-maintained, not abandonware.

The catch

Self-hosted means you must own a domain, configure DNS, and manage a Linux server (min. 2 GB RAM). No PDF/ePUB/Kindle export, no native mobile apps, and minimal integrations.

Best for
Developers or technical teams publishing internal docs or manuals
Indie authors wanting a self-controlled online reading experience
Organizations moving long-form content off proprietary SaaS platforms
Not good for
Non-technical users who can't manage a VPS
Authors needing PDF, ePUB, or Kindle export
Teams needing analytics, paywalls, or deep third-party integrations
Friction report
Time to value
Slow: requires domain registration, DNS setup, and server provisioning before first book is live — not a five-minute signup.
Scale breakpoint
Server resources: a single low-cost VPS handles small to medium traffic, but heavy public traffic requires manual scaling.
Walled garden
Low: you own the server and the full source code; no lock-in beyond the Rails stack.
