Built with Hydra Engine

Projects made by reverse-engineering programs their authors own, with Hydra Engine and Hydralysis. The showcase on the website reads this repository's index.json, so a project merged here appears there.

Add yours

By pull request. Make a folder projects/<your-project>/ (lowercase words joined by -) with:

• project.json, following project.schema.json:

  {
    "name": "My Project",
    "url": "https://github.com/you/my-project",
    "from": "what you reverse-engineered",
    "to": "what it became",
    "kind": "game",
    "text": "One or two sentences, in your words, shown on the card.",
    "author": "you",
    "stack": ["Claude Code", "Hydralysis"],
    "highlights": ["a measured fact", "another"],
    "added": "2026-10-27"
  }

• one cover image, cover.jpg, cover.png or cover.webp: 1200x630, at most 600 KB.

Then run python scripts/build_index.py (Python 3, standard library only) and commit the updated index.json. CI runs python scripts/build_index.py --check on every pull request.

By issue. Open an Add a project issue, attach the cover, and a maintainer adds it.

Rules

• Only programs you own, and no code, assets or data from them in your project.
• A link people can open: a repository, a release, a write-up or a video.
• A cover you have the right to share. Covers and descriptions belong to their authors, who license them for display on this showcase and the Hydra Engine website. Fan projects use their subject's name to say what they are, not to claim any affiliation.
