SEO and marketing decision
Replymer
A capable developer can build a constrained self-hosted replacement for Replymer's core tracking, draft generation and queue UX, but reproducing multi-engine coverage, the hosted MCP agent experience, and commercial analytics polish would be hard to match.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Periodically run buying-question prompts for a domain through target AI engines, collect the answers and their cited sources, surface gaps where competitors are cited but you aren't, generate ready-to-post reply drafts, queue those actions, and let the user post from their own account (or have an agent drive a browser to post).
What it still won’t have
- Full out-of-the-box coverage and normalization across six AI engines and their answer formats
- Hosted MCP server and turnkey agent connectivity
- White-label reports, team seats and built-in attribution plumbing
- The commercial SLA, usability polish and the product’s hosted analytics dashboards
What remains hard
- Brand trust

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal Replymer-like service using Next.js (React) frontend, a Postgres database, a Node.js worker (BullMQ) and a small REST API. Core features in scope: (1) project and tracked-prompt CRUD, (2) scheduled worker that queries a configurable list of AI engines (start with OpenAI Chat completions and one scraping-backed engine) for answers, (3) extract and store cited source URLs and mentions, (4) generate reply drafts via OpenAI and surface them in an action queue, (5) a web UI to review, edit and mark actions done, (6) a simple MCP-compatible webhook endpoint for agents to poll list_actions/get_action/mark_done, (7) basic stats endpoint (citation share by source). Out of scope: full six-engine normalization, hosted MCP server, browser automation for posting, white-label reports, multi-seat billing. Include authentication, input validation, error handling, unit and integration tests, Docker-based deployment manifests, and a README with setup and run instructions.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
