You want a public prioritization signal for what to build next, without building a voting feature yourself.
Issue trackers don't map to "email me when it ships," and dedicated feedback tools are a recurring subscription just to collect votes.
Enlist's own roadmap runs on this: each feature is a waitlist, a vote is a signup, and the count on the page is live from the same public API — nothing behind it but Enlist itself.
A real API key, the MCP server, and signup emails — no credit card.
