corx

Link-preview service in Rust, for bare-metal servers and Cloudflare Workers. Give it a URL, get the Open Graph / Twitter Card metadata needed to render a link card.

• corx — sans-IO core: URL admission, SSRF rules, streaming metadata extraction and the shared request pipeline (wasm32-unknown-unknown clean)
• corx-server — the corx binary (axum + reqwest)
• corx-worker — the Cloudflare Worker (workers-rs)

Quick start

cargo run --release -p corx-server -- --allowed-origins https://app.example.com
curl 'http://localhost:8080/v1/preview?url=https%3A%2F%2Fexample.com'

corx --help lists every flag with its CORX_* environment variable. The Worker is configured in crates/corx-worker/wrangler.jsonc and deployed with wrangler (ALLOWED_ORIGINS must be set).

Changes are tracked in CHANGELOG.md; contributor invariants and the local gate live in AGENTS.md and CONTRIBUTING.md.
