BrewPage vs Wandbox

BrewPage is a free, account-less content host: a POST to endpoints like brewpage.app/api/html turns HTML, Markdown, JSON, key-value pairs, or a whole multi-file site into a short public URL, protected by an anonymous owner token instead of a login. Pages default to a 15-day TTL (30-day max) and can be password-protected, and the project ships both an MCP server (brewpage-mcp on npm) and a Claude Code plugin for programmatic publishing.

Wandbox is a free "social compilation service" built by melpon and kikairoya, offering 175 compiler configurations across 35 languages — from mainstream C++, Python, Rust, and Go to niche picks like Lazy K and Pony — including nightly HEAD builds of GCC and Clang. Its REST API needs no key: POST source code, a compiler ID, and options to /api/compile.json (or the /ndjson variant for streamed output) and get back compile/runtime output plus a permanent shareable permalink, while /api/list.json enumerates every compiler and its supported switches. The project was rewritten in 2024–2026 from a legacy Ruby backend to Rust (feline) and Remix (canine), which is why the old kennel2/API.rst docs path 404s — the live API endpoints themselves are unchanged.
