Carstio is free, open-source software for modern car services - a clean tool for tracking jobs, customers and vehicles without the bloat, subscriptions, or vendor lock-in.
Most workshop software is built to sell. It ships with dashboards nobody opens, modules nobody asked for, and a monthly bill that scales with your team. Carstio is the opposite: a clean, self-hosted app that does the few things a service garage really needs - jobs, customers, vehicles, parts, invoices.
It runs on standard PHP on almost any shared host. No SaaS, no telemetry, no upsells. The source is yours.
Carstio is small on purpose. Every feature has to earn its place, and anything that doesn't serve a working garage gets left out.
MIT licensed. No seats, no tiers, no "contact sales". Fork it, ship it, run it.
Plain PHP and Twig. Drop it on a shared host or your own computer, point it at database, you're running.
Readable code, no vendor lock-in. Bend it to fit your workflow, not the other way around.
Carstio is in active development and welcomes contributors - mechanics, shop owners, and engineers alike. Star the project, file an issue, or send a PR.
