Real infrastructure.
Open to everyone.
ndexr is live high-performance computing we run our own production work on. Sign in and the same platform is yours — yourname.ndexr.io , an agent, your code, and a live site. Describe what you want; it gets built on the real thing. Every version saved and reproducible.
Still in early access. Free to start, no credit card.
Most ideas never become real things. We change that.
You don't need to know how to code. You don't need a developer. Sign in, describe what you want, and it gets built — a real working site at your own address, yours to keep. And every version is saved, so you can always see how it was made and rebuild it exactly.
Real, validated infrastructure
We build on this every day. So can you.
ndexr isn't a sandbox — it's live high-performance computing we run our own production work on, and you log into the same system. The whole software stack is compiled from source, cryptographically signed, and distributed so every machine runs the exact same bytes, checked on every read. That's lab-grade reproducibility — on by default, for everyone. It's all public; here's the machinery.
For anyone with an idea
Personal projects
A habit tracker. A quiz for your group chat. A game for your kids. A tool for your weird hobby. Describe it and it gets built — no technical knowledge needed.
Work & small business
A booking page. A staff schedule. A client form. Describe how you work and it gets built that way — not the way a template decides you should.
Curious minds
Want to understand how software gets made? Build something real, watch decisions happen, change your mind halfway through. The best way to learn is by making things.
How it works
Describe your idea
Describe what you want in plain words. Half-formed is fine. It can be a game, a tool, a form, a tracker — anything. Ask questions, get answers, figure it out together.
Watch it get built
It builds right in your browser, step by step — and every step is written down. You steer, you change your mind, you keep going. The real thing, not a mockup, with a record of exactly how it was made.
You own it
Your site lives at yourname.ndexr.io. Your data, your code, and the full history of how it was built. Walk away anytime — you take everything with you, and it rebuilds exactly the same, anywhere.
The architecture
Every domain is a workspace. One system serves them all.
Each domain carries everything you need to build it — an agent, a terminal, a VS Code session, a Git repo, and the live site. nginx routes every address into one Shiny app where each site is just a module, so a single repo already serves 120+ live domains . You add a module, not a codebase.
Why it's a better deal
No seats. No tiers. No ceilings.
Many platforms charge by the seat and keep the features you need behind upgrade tiers. We take a simpler approach: the capabilities are on by default, what you build is yours, and you can take it with you whenever you like.
The usual model
- Priced per seat — the bill climbs with every person you add
- Access controls and private sharing locked behind upgrade tiers
- Custom domains rationed by plan: one, then five, then ten
- Fixed RAM and CPU caps for every piece of content
- Security, compliance and scale mean enterprise procurement and a sales call
- Your work lives on their platform
With ndexr
- No per-seat tax — share with your team, your customers, or the whole public
- Access controls and private sharing included from the first day
- Bring as many domains as you want, all under one system
- Runs on real high-performance infrastructure, not a fixed tier
- Validated, reproducible and on-prem capable — without a long procurement process
- Your code, your data, your repo — export everything and walk anytime
For teams that need it inside their own walls
The whole platform, installed where you control it.
The reproducible, on-the-record builds everyone gets here are the same ones a regulated lab can validate. Everything that runs ndexr.io can run inside your own infrastructure — on-prem, air-gapped, or in your private cloud: many users and many applications under one validated install, where every version has to be accounted for.
Reproducible builds
Every dependency pinned, every image content-addressed. The build you validate is the build that runs — bit for bit, every time, on any node.
Many users, many apps
One platform serving isolated tenants. Each user gets their own apps, data schema, and access boundary. Scale horizontally across an HPC cluster.
Validation-ready
Designed for GxP and other regulated environments. Audit trails, deterministic deployments, and documented build provenance to support IQ/OQ/PQ.
The same platform we run in production — installed and validated inside yours.
