Open source · Apache-2.0 — and this site is itself an Indigo install

Describe what you want. Your agent ships it — and proves it's done.

A website, a blog, a shop, a full SaaS — describe it in chat, and your coding agent — Claude Code, Codex, Gemini, any of them — builds it on one pre-wired, open-source foundation and loops until it's verifiably done: checks green, user journeys tested. Not a website builder. Not a template. A production Next.js codebase you own.

See it

From one prompt to a shipped product

The whole story in about 80 seconds — a real install, a full admin dashboard, and the real product reshaped live on request. Real footage from the live demo. Tap for sound.

Getting started is one prompt

Hand your agent the repo URL — it reads the instructions for agents in the README, installs everything, and asks you the questions in chat: modules, site name, admin account. Then it runs the whole install itself.

No terminal at all? In the Claude Code desktop app, pick an empty folder for a new session and say the same thing — with "here" instead of a folder name.

The agent asks the questions; no CLI prompt ever blocks on you

How it works

A loop, not a leap of faith

Hand the agent one request — or a whole goal, /loop-style, and let it run unattended. It can, because on Indigo 'done' isn't an opinion: it's checks going green and personas completing the journeys.

1 · Describe

You say what the product should be, in plain language, in chat. That is the whole job description.

2 · Build

The agent orients from the map — nested CLAUDE.md files and live diagrams — and extends through config and modules, never by editing shared core.

3 · Verify

Typecheck, tests and indigo doctor grade the pass. Then the agent logs in through MCP as a seeded persona and uses the feature like a customer would.

4 · Improve

Failures feed straight into the next pass — no human relaying error messages. The loop only exits when done goes green: checks pass, journeys verified.

Watch it happen

The loop, mid-flight

One request, start to finish: the agent builds, gets graded, fixes its own miss, and proves the whole install still holds — the full test suite, the health checks, everything. Terminal output verbatim from real runs. What reaches you is a readable diff.

Why Indigo

Because a prototype isn't a product

Your agent isn't just your developer — on Indigo it's the whole team: the designer, the tester who logs in and clicks through every journey, the translator who ships all 17 languages, the maintainer who keeps improving after launch. That's what turns a demo into a business that holds up.

Proper architecture from day one — pass 100 lands as cleanly as pass 1.
Everything pre-wired — auth, billing, CMS, admin panel, 17 languages, SEO.
Self-verifying changes — the agent logs in and tests like a real customer.
Cheap iterations — the agent orients from generated maps and pointer docs, not by re-reading the codebase.

It improves after launchscheduled improvement passes handle maintenance, translations and test coverage.
You stay the director — describe, review diffs, decide; the agent asks in chat.
A real codebase — typed, tested, readable; take the wheel anytime.
No lock-in — Apache-2.0 yours, fresh repo, your database, your deploy.

Vibe-code without the crash

Not a site builder. Not a boilerplate. Built for the loop.

Agents don't fail from lack of intelligence — they fail from lack of environment. Whatever you'd use instead, the gap is the same: the loop needs a map of the system, a signal when something breaks, and hands to test what it built. Indigo is designed around all three.

Lovable · Bolt · v0

vs. hosted AI builders

They generate your app on their platform — great for a prototype, but the day it must become a product, you hit the export cliff. Indigo starts where they end: a real repo on your machine, typed and tested, that your own agent keeps building. No platform. No cliff.

vs. boilerplates

A boilerplate is a snapshot: you inherit its glue code, maintain it forever, and it tells your agent nothing. Indigo is a framework — the agent extends it through config and modules, never edits shared core, and upgrades land cleanly under your features.

Empty repo + any agent

vs. vibe-coding from scratch

The agent improvises a foundation, then drifts — nothing tells it what broke, and it can't use what it built. Indigo removes the drift: types, tests and indigo doctor grade every pass, and seeded personas let it log in and verify like a customer.

What's in the box

A real business, not a scaffold

The free core every install ships with — working product surfaces the agent extends, so no pass of the loop is ever spent writing glue.

Integrated CMS

Config-driven content types, revision history, media library, scheduled publishing, shortcodes and a content calendar.

Auth & organizations

Better Auth with RBAC, multi-tenant organizations, social login and team management.

Admin panel on day one

Content, media, users, forms, custom fields, audit log and analytics — a full back office you didn't have to build.

Real-time & background jobs

WebSocket updates with Redis pub/sub, BullMQ workers with a database fallback — live features and async work, wired.

Type-safe, end to end

PostgreSQL through Drizzle and tRPC to the client in one typed chain — which doubles as the loop's error signal.

17 languages, agent-translated

Locale routing, hreflang, multilingual sitemaps, JSON-LD and RSS. Describe the site once; your agent ships every locale — this site's 17 languages were translated exactly that way.

Agent-built is half the story. Your product is agent-operable, too.

The same MCP endpoint the build loop uses ships with your app to production. Every API procedure is a typed tool behind API keys or OAuth — so "connect your AI to our product" is a day-one fact about your business, not a roadmap item.

Every tRPC procedure doubles as a typed MCP tool — a curated list up front, the full registry on demand
The same guardrails as the UI — auth, ownership checks and org scoping apply to agents too
/llms.txt gives any visiting agent the guided tour of your product

POST /api/mcp           every API procedure, as a typed tool

Modular architecture

Need a store? A support desk? Just a blog? Say so.

Modules are self-contained git subtrees — routers, schema, seeds and admin pages included. You name the capability; the agent adds it in one command, or removes everything your project will never use. The core and 14 modules are free — only three are paid, each a whole product of its own, and most projects never need one.

For developers

Still just code. Still yours.

Agent-built doesn't mean black box. Every pass of the loop lands as a readable diff in a codebase that stays typed, tested, Apache-2.0 yours — take the wheel whenever you want.

Readable diffs

Agents extend through config and registration, so changes are small, local and reviewable — not sprawling rewrites.

Guardrails on

Strict TypeScript, Zod-constrained inputs, ownership checks and soft-delete conventions hold for agents and humans alike.

No lock-in

degit ships no history; bun run init makes a fresh repo. It's your code, your database, your deploy target.

Proof, not promises

You're looking at one

This site is itself an Indigo install — and every page, in 17 languages, was translated by a coding agent in a single pass. Switch languages in the header and see for yourself.

17 languages, one loop

Describe the site once; the agent shipped every locale. Going international is a prompt, not a project — and this page is the receipt.

Dogfooded end to end

indigo-fw.dev, the live demo and the docs are all Indigo installs. The framework builds its own front door.

Open by default

Apache-2.0 core, every free module you see here included. Clone it, read the diffs, make it yours — no license to buy.

Start the loop

Describe what you want to build, and let your agent run. The framework and its free modules are Apache-2.0 — yours to use for anything, including commercial work. And if you want proof it holds up, you're reading it: this site is an Indigo install.
