Nullcost catalog + plugin

Ask for free tiers. Get a catalog-backed shortlist.

Nullcost gives coding agents a hosted database of developer tools with free tiers, trials, and approved community code paths. Less vendor-tab chaos. Fewer stale guesses.

Install path

Pick OS. Pick app. Copy command.

Install the plugin once, then ask normal free-tier and provider questions inside your coding app.

CodexmacOS

npx -y nullcost-plugin@latest install codex

Best path when you use Codex. Installs the plugin wrapper plus MCP server.

Config path: No path needed. The installer handles Codex plugin placement.
Then ask: find me a hosting provider with a free tier

Example provider row

One provider can have several free-entry paths.

This mock row shows the edge cases Nullcost needs to explain clearly: free plans, trials, referral bonuses, coupons, affiliate links, and stackable link-plus-code paths.
