Open-source tooling for Pro Cycling Manager.
PCMStack is a community-driven collection of tools, libraries, and apps built around Pro Cycling Manager — the cycling management simulation. Our goal is simple: make PCM's data open, accessible, and fun to build on.
Every PCM career lives inside a .cdb database file — a SQLite database packed with riders, teams, races, and stats. It's a goldmine, but it's locked behind an undocumented format that's hard to read, edit, or extend.
PCMStack is where we fix that. We build the small, sharp, composable tools that turn PCM saves into something you can actually work with — whether you're a modder, a data nerd, a save editor, or just someone who wants to win a Grand Tour with a rider nobody believed in.
Open format. Open tooling. Built in the open.
Our ecosystem is made of focused pieces that work great on their own and even better together.
| Project | What it does | Status |
|---|---|---|
| converter | Converts .cdb save files to SQLite and back. Round-trip safe, zero config. |
Stable |
| mcp | MCP server that lets Claude query and edit your saves in plain language. | Beta |
| editor | Web-based database editor. No spreadsheet gymnastics. | In progress |
| studio | Full desktop modding suite. | Planned |
More tools are on the way — parsers, editors, and utilities for the .cdb format. Watch this space.
We're fans of the Unix principle: small tools that do one thing well and compose cleanly. Each project in PCMStack is independent, but they share a common backbone — a clean, reliable way to read and write the PCM save format — so you can pick up one piece without swallowing the whole thing.
This is a community effort, and contributions are genuinely welcome — whether that's code, bug reports, format documentation, or just telling us what you'd want to build.

- 💡 Have an idea? Start a discussion or open an issue — we'd love to hear it.
- 🔧 Want to contribute code? Fork, branch, and send a PR. Check each repo's
CONTRIBUTINGnotes first. - 🧩 Reverse-engineered part of the
.cdbformat? That knowledge is gold. Share it.
Most of the stack is built in TypeScript / Node.js, working against SQLite under the hood, with a focus on portability and clean, documented APIs.
