Why I built this
Most free ATS resume checkers are built for the US job market. They flag CGPA as "unnecessary personal data," don't understand fresher/campus-project resumes, and give the same advice regardless of whether you're applying to a private company or a government/PSU role in India — where the same detail (DOB, photo, father's name) means completely opposite things depending on who's screening you.
So I built ATSMeter — a free, unlimited ATS resume checker (plus cover letter and LinkedIn About checkers) made specifically for Indian job seekers.
The interesting technical decisions
No LLM in the scoring path. Every finding is a deterministic, rule-based check — regex patterns, layout heuristics from pdfplumber (two-column detection, header/footer band detection for contact info), keyword matching. Same resume in, same score out, every time. No black box, no hallucinated feedback, and it means I can explain every single finding with the exact reason behind it.
No framework, no build step. The frontend is plain HTML/CSS/JS across three pages. No React, no bundler, no TypeScript. For a tool this size, that means instant load times, zero dependency-update maintenance, and I can read the entire codebase top to bottom in a sitting.
Firebase Auth via raw REST API, not the SDK. Sign-in is optional (email-link, passwordless) and only unlocks cross-device score history. I called Firebase's REST endpoints directly instead of the Firebase JS SDK, specifically so I could keep a strict CSP (script-src 'self') — no third-party script CDN needed at all.
Nothing is stored, structurally. Your resume/cover letter/LinkedIn text is parsed in memory for the duration of one request and discarded. If you sign in, we store only score/type/filename/date — never the actual content. This isn't just a privacy policy sentence, it's enforced by the code path itself: there's no code that ever writes resume text anywhere.
It's a real PWA. Installable on iOS/Android/desktop, works offline via a service worker caching the app shell, with network-first fetching so a new deploy shows up immediately instead of needing a stale cache to expire.
What it checks
Two-column layouts and tables that scramble when an ATS parses them
Contact info accidentally sitting in a header/footer band that some parsers skip
CGPA, fresher/campus-project resumes (scored on their own merit, not penalized for missing "experience")
Govt/PSU vs private-sector targeting — same resume, different rules, because the right answer genuinely differs
Passive/filler phrases with suggested action-verb rewrites
Missing quantified results
Stack
FastAPI + pdfplumber/python-docx on the backend, deployed on Google Cloud Run. Vanilla JS frontend, Firebase Auth/Firestore/Cloud Storage for the optional account features (private bucket, served only to its owner — no public URLs).
It's free, unlimited, and takes about 10 seconds — no sign-up required to check a resume.
