The foundation should be a solved problem
Every SaaS rebuilds the same plumbing before it writes a line of product. Indigo exists to make that foundation something you adopt — not something you assemble.
Boilerplate is a tax you pay before you start
Auth. Billing. A CMS. Email. Background jobs. Real-time updates. File storage. An admin panel. Internationalization. Every product needs them, and none of them are the product.
The conventional answer is to assemble these from a dozen libraries. The result is fragile glue code that nobody owns, that breaks on upgrades, and that no new engineer — or AI agent — can reason about quickly.
Weeks lost up front
Glue code rots
Illegible to agents
One cohesive framework, not a pile of libraries
Every layer already knows about the others
Indigo is a single, type-safe system. Auth knows about organizations. Billing knows about auth. The CMS, jobs, real-time layer and admin panel share one data model and one set of conventions.
You extend Indigo the way it was designed to be extended — by registering content types, modules and features through config. You never fork shared code, so upgrades stay clean.
Open-closed by design
New capabilities register themselves. A content type is a config entry. A feature is a module. A background job is a registration call. Because nothing edits the core, the framework can be upgraded under you — and an AI agent can add features without understanding the entire codebase first.
A codebase agents can read, navigate and extend
Documented everywhere
Nested CLAUDE.md files at the root, core, every module and config explain intent, not just code.
Predictable structure
Strict module boundaries and config-driven extension points mean an agent always knows where new code belongs.
Self-describing
indigo visualize and indigo doctor turn the live codebase into diagrams and health reports an agent can consume.
Open source, with a path to production
The core framework and essential modules are free and open source under AGPL-3.0. A commercial license is available for proprietary use. Premium modules — e-commerce, AI chat, support — fund continued development.
You own your install from the first commit: degit ships no history, bun run init creates a fresh repository, and the code is yours.
See it for yourself
The fastest way to understand Indigo is to use it. The live demo is a full install with every module enabled.
