Open Apps

A hand-picked directory of real open-source applications — apps worth running, studying, and extending.

Why this list

GitHub search works when you already know what you are looking for. This list is for the other case: discovering real, production-grade apps — not tutorials, boilerplates, or package-only libraries — and understanding what each one is worth your time for.

Every entry is a human-curated YAML record in data/records/, kept fresh by weekly GitHub metadata syncs. To add an app, use the submission form or open a pull request — see CONTRIBUTING.md.

About this project

The list above is one view of the catalog. The same YAML records also build openappscout.com — a searchable directory with per-app detail pages, curated collections, stack and category browsing, and contributor credits.

• Every app is one file: data/records/<slug>.yml. The schema and field ownership rules are documented in docs/SCHEMA.md.
• Human-curated fields and automation-owned GitHub metadata live side by side in each record; scheduled jobs refresh the metadata through reviewable pull requests.
• The site is built with Grove on Astro and Tailwind CSS, and deploys as a static site to Cloudflare.
• The list section of this README is generated from the records with grove readme generate — edit the YAML, not the list.

Add or update an app

The fastest path is the web form: it drafts a YAML record from a public GitHub URL; you review the taxonomy and open a pull request.

For a manual contribution:

1. Create or edit data/records/<slug>.yml.
2. Run pnpm exec grove check and pnpm build.
3. Open a focused pull request.

Inclusion criteria — what belongs, what does not, and how entries are reviewed — are documented in CONTRIBUTING.md. All participants follow the Code of Conduct.

Development

Requires Node.js 22.12 or newer and pnpm (pinned in package.json, available via corepack enable).

git clone https://github.com/tortuvshin/open-apps.git
cd open-apps
corepack enable
pnpm install --frozen-lockfile
pnpm dev

Automation

GitHub Actions keeps the catalog fresh without silent changes:

• Every push and pull request — CI runs an icon drift check, grove check, and a full site build.
• Weekly — GitHub metadata sync, contributor sync, and README regeneration, each landing as a reviewable pull request.
• Monthly — a cleanup report flags stale records for curator review; nothing is removed automatically.

AI-readable catalog

The deployed site publishes llms.txt, a compact guide to the site, and llms-full.txt, the expanded catalog for AI assistants and retrieval tools — generated from the same records as everything else.

Project history

Open Apps grew from open-source-flutter-apps. The original README-only collection is preserved in README-LEGACY.md, while this project evolves it into a structured, searchable, multi-stack directory.

Security

Report vulnerabilities and sensitive issues through the private process in SECURITY.md — never in a public issue.
