Open-source customisation

Build your infrastructure on open source; we write the missing piece and look after it once it is live

API gateway (Kong, including plugins we write), file transfer (SFTP/SFTPGo), open-source remote desktop (RustDesk instead of TeamViewer), identity (Keycloak), content platforms (Strapi, n8n, WordPress), AI usage monitoring (Token Monitor, plus a web dashboard), uptime monitoring (Uptime Kuma, which can be turned into a multi-node high-availability cluster). We use these ourselves as well.

A good fit when

  • You want to avoid licence fees but need someone to install it, wire it up and keep it running
  • The open-source option fits 80% and the missing 20% needs a plugin or module
  • You need someone accountable for upgrades and security patches instead of watching CVEs yourself

Not a fit when

  • The gap between your needs and the project is so wide that rewriting beats patching
  • You cannot accept open-source licence terms

What we can set up or customise for you

  1. 01Kong API gateway: routing, auth, rate limiting, observability, plus custom Lua plugins
  2. 02SFTP file transfer and self-hosted remote desktop (RustDesk, with no third-party server in the path)
  3. 03Custom plugins or modules with source, plus deployment and upgrade runbooks
  4. 04Someone looks after it once it is live: version updates, security patches and code adjustments based on how you actually use it, under a maintenance plan

    Token Monitor team AI usage dashboard

    See how your team actually uses AI: who uses which tools, how much, at what cost, and how much of each subscription is left. We collect usage records from each computer with the open-source Token Monitor (MIT; it supports 43+ AI coding tools such as Claude Code, Codex and Cursor), combine the machines through a Hub, and add the web dashboard the project does not ship, so the whole team's usage is visible in a browser.

    • Per computer: which AI tools each colleague's machine uses, today's and this month's tokens and cost, and when it last reported
    • Reads only the usage records each tool leaves on the computer (token counts, model, time); it does not read prompts or code

Frequently asked

Yes. We have written Lua plugins for signature verification, request rewriting, and hooks into our own auth and metering. Plugins stay separate, so a Kong upgrade does not overwrite them.
