It leverages the Model Context Protocol (MCP) to eliminate the manual steps that cause over half of agreed backlink trades to fail, integrating the exchange into the developer's existing workflow.
A free backlink exchange for indie builders, driven from your coding agent.
Submit a site, get matched with another builder in your category, and trade one link each. The whole exchange is exposed as an MCP server, so the trade happens where the work happens.

Ranking Raccoon publishes that 71% of link requests get a reply and only 35% become a published link.

pnpm dev is Next on Node, which is convenient and is not the production runtime. CLAUDE.md has the full command list, how to run it the way it actually deploys, and the workerd behaviour that only shows up there.
