Open source

Our engineering doctrine is public.

How we work is not a slide in a pitch deck. It is a published repository you can read, run, and hold us to. We also publish product work, so you can see the doctrine after contact with a real codebase rather than only in the abstract.

Public repositories
  • Paylo-One/engineering-constitutionEngineering doctrine · Licence Apache-2.0The doctrine itself: 25 durable engineering principles, the mandatory engineering sequence, work classification, an operational skill for each engineering discipline, and templates for requirements, system design, decision records, threat models, and production readiness.
  • Paylo-One/pilot.paylo-one.reactWorking product, TypeScript · Licence AGPL-3.0A working product built under the constitution: a multi-tenant application with connected data sources, background processing, and AI-assisted output. Read it to see the principles applied rather than described.
Read before you commit

You can audit how we work before you brief us.

Most firms ask you to take their engineering standards on trust. Ours are in public version control, with a full history of how they changed and why. Start with AGENTS.md for the sequence and PRINCIPLES.md for the reasoning.

Client work is never published. Engagement material stays in your repositories and your environments, under the agreement that governs it. What you see here is our own work, licensed as each repository states.

Pilot is open source.

The full Pilot application is open source under AGPL-3.0. Inspect every line, run it on your own infrastructure, keep your data under your own control. Or let us operate it for you.

Self-host Pilot

Clone the repository and run Pilot yourself: your server, your database, your own model keys. No telemetry, no feature gates, no account with us required.

  • The complete application, not a limited community edition
  • Docker Compose or a plain Node 22 server, with a full self-hosting guide
  • Bring your own model provider. OpenAI-compatible, including EU-resident options
  • AGPL-3.0: free to use, modify, and self-host, forever

Start with discovery

Bring us the system you are worried about.

Tell us what you are building or what keeps failing, what constrains it, and when it has to work. You will get a considered reply about what we think the real problem is, and an honest view of whether we are the right firm for it.
