OpenStove is a community recipe site where every recipe is a Markdown file in this repository. Readers get recipes with no ads, no fees, and no account – just the dish, scalable to any number of servings. Contributors add a recipe with a form or a pull request, and because both the code and the recipe text are open, anyone can fork the whole site and run their own.

Browse it live at openstove.org.

• Open content. 80+ recipes, licensed under CC BY-NC-SA 4.0, each one a plain Markdown file you can copy, edit, or fork.
• No account needed. Bookmarks are stored in your browser only. Nothing to sign up for, nothing tracked.
• Cooks for any table. A servings stepper scales every quantity, and a US / metric toggle converts cups, pounds and ounces to grams and millilitres.
• Two ways to contribute. A web form that needs no Git knowledge, or a pull request for a Markdown file. Both are reviewed by maintainers on GitHub.
• Print-ready. Every recipe page prints cleanly and exports to PDF from the browser.
• Built to fork. Astro, Tailwind CSS, Keystatic CMS and Vercel. Clone, pnpm dev, and you have a working recipe site.

A recipe is one file. Its name is its URL:

# src/content/recipes/creamy-tomato-soup.md  →  openstove.org/recipes/creamy-tomato-soup

Getting started

You need Node.js 22.12 or newer and pnpm.

git clone https://github.com/mearashadowfax/OpenStove.git
cd OpenStove
pnpm install
cp .env.example .env
pnpm dev

Open http://localhost:4321. The site runs fully without any environment variables: recipe pages show a placeholder photo, and the contribute form is disabled until you add GitHub credentials (see Deploying your own).

Other scripts:

pnpm build          # Type-check and create the production build
pnpm preview        # Serve the production build locally
pnpm test           # Run the test suite
pnpm format:check   # Check formatting
pnpm format:fix     # Apply formatting

Contributing a recipe

No Git? Use the contribution form. It opens a GitHub Issue with the generated Markdown, which maintainers review and merge.

Prefer a pull request? Add a file to src/content/recipes/ and open a PR. The full guide, including the recipe template and naming rules, is in CONTRIBUTING.md.

Recipe text you contribute is licensed under CC BY-NC-SA 4.0, like the rest of the project. Photo rights stay with you unless you grant them explicitly.

---

Recipe format

Recipes live in src/content/recipes and are validated against the schema in src/content.config.ts at build time. The frontmatter is the recipe; the Markdown body is unused.

The filename is the recipe ID and URL path, so do not add a slug field to the frontmatter.

Key rules:

• Quantities are numbers only. '1/2', '1.5', '1 1/2' and '3-4' are valid; '125g' is rejected. Put the unit in unit.
• Scaling. By default a recipe is written for one serving and readers get a stepper. For a whole dish (cake, pie, loaf) set servings: 8 and scalable: false; readers then see "Serves 8".
• Tags. Lowercase, up to three, each one gets its own page.
• Long titles. Cards clamp titles to two lines. If the full title is long, add an optional cardTitle for the card; the recipe page keeps title.

A blank copy with no placeholders is in Ready-to-go-Template.md.

Recipe photos

Photos are not in this repository. They are served from Vercel Blob so licensed image files stay out of the public Git history. Frontmatter stores only the filename:

image: 'tomato-soup.avif'
imageAlt: 'A bowl of creamy tomato soup'

The site prepends PUBLIC_IMAGE_BASE_URL to that filename. Without the variable, or when a photo is missing, the page shows the fallback image from public/placeholder-recipe.png.

To upload photos, keep the originals in a private directory and run:

BLOB_READ_WRITE_TOKEN=vercel_blob_... \
pnpm upload:images --dir /path/to/private-recipe-images

The script uploads every .avif under the recipes/ Blob prefix and prints the PUBLIC_IMAGE_BASE_URL to set.

Never commit recipe photos or Blob write tokens to this repository.

---

Editing with Keystatic

Maintainers can edit recipes in a web UI instead of raw YAML:

• Locally: run pnpm dev and open http://127.0.0.1:4321/keystatic. It reads and writes files in your working tree directly.
• In production: /keystatic uses GitHub authentication. Only users with write access to the repository can make changes.

Deploying your own

OpenStove is built for Vercel, using server rendering and serverless routes.

1. Fork and import this repository into Vercel.
2. Create a public-read Vercel Blob store and connect it to the project.
3. Upload your recipe photos with pnpm upload:images and set PUBLIC_IMAGE_BASE_URL.
4. Set the contribute-form variables. All three are required in production:

   GITHUB_TOKEN               Fine-grained PAT with Issues: read and write
   GITHUB_REPO                your-user/your-fork
   TURNSTILE_SECRET_KEY       Cloudflare Turnstile secret (spam protection)
   PUBLIC_TURNSTILE_SITE_KEY  Cloudflare Turnstile site key
   

   Locally, Turnstile is waived; only the GitHub variables are needed.
5. Set the Keystatic GitHub-app variables if you want the production CMS.
6. Deploy the main branch, then check recipe images, /contribute, /keystatic and print output.

.env.example lists every variable with a comment.
