Free & Open-Source Apps
Software I built, open-sourced and gave away — host it yourself, no cost, no lock-in.
Ownership you can verify
I tell clients they'll own what I build for them. This page is where that claim stops being a promise and starts being something you can check. Every app below is 100% free under the permissive MIT license — use it personally or commercially, modify it, ship it inside your own product. Most self-host with a single docker compose up (Swissberry runs on a Raspberry Pi), so your data stays on your hardware. No accounts, no fees, no vendor lock-in.
It's also the easiest way to judge the work before hiring anyone: read the code.
ToBeExpected
A tiny self-hosted telemetry sink. Send events — HTTP requests, background jobs, database queries, audit logs, anything worth tracking — to one endpoint and browse, filter and search them live in a clean dashboard. Drop the client SDK into any backend or frontend and watch its activity stream in.
Simply Analytics
Privacy-first, cookieless web analytics you host yourself. Drop a tiny script on your site and see page views, visitors, referrers, technology and geography in a clean dashboard — no cookies, honors Do-Not-Track, and your visitors' data never leaves your server.
FormJet
A self-hostable form-to-email API. Point your website's contact form at FormJet and it validates the submission, filters spam (honeypots, rate limits, auto-bans), and delivers it by email — no backend of your own and no third-party form service.
Ledgerly
A family budget tracker you actually keep using. Set your recurring income once and it becomes each month's budget; enter expenses as they happen. It then tells you where the money went, what jumped since last month, and what a specific change would save — with history, trends and savings or debt-payoff goals projected from the surplus you have really been running. Mobile-first, light and dark. An optional local AI writes the monthly summary and is never allowed to state a figure.
Swissberry
A network professional's swiss army knife for the Raspberry Pi. Scan the LAN and Wi-Fi (including hidden and mesh networks), capture and decode traffic in a Wireshark-style viewer, discover Bluetooth and RFID, and automate IT-support tasks over USB — all from a mobile-first web dashboard or an on-device screen. A troubleshooting tool, not a hacking tool: every active feature is authorization-gated.

Happy to do that. And if the tool your business really needs doesn't exist yet, that's the custom software side of the work.
