ResumeFast
A single competent developer can reproduce the core product (resume parsing, LLM rewrite, ATS checks, templates, exports) using existing open-source projects and LLM APIs; the hosted product's UX polish, human expert reviews, and any proprietary ATS tuning are the main things you would give up.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All ResumeFast alternatives, with the arithmetic →
What a replacement has to do
- User imports or types experience → AI rewrites bullets tailored to a JD → run ATS scanner and auto-fix suggestions → choose template and export PDF/DOCX.
What it still won’t have
- Polished, tested UX and polished template gallery
- Any proprietary ATS scoring dataset or tuning the vendor may have
- Built-in expert human review/fast human support
- Analytics, reviews, and brand trust of the hosted product
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal AI resume builder using Next.js (React) frontend, Node.js/Express backend, Postgres for user/profile storage, OpenAI-compatible LLM API for rewriting prompts, a heuristic ATS-scoring service (keyword matching + formatting checks), and Puppeteer or LibreOffice for PDF/.docx generation. Core features in scope: LinkedIn import or file upload + parse to structured schema, LLM-backed bullet rewriting with prompt templates and rate-limiting, ATS scanner with per-resume report, template rendering and PDF/DOCX export, user account and single-profile persistence, and a simple billing toggle for Pro features. Out of scope: human expert review service, marketing site polish, large-scale analytics, enterprise SSO. Include auth, error handling, unit/integration tests for parsing, LLM integration, ATS rules, and PDF exports, and provide Docker-based deployment and a basic CI workflow.

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.
