OfferLens is a browser-only job-offer comparison tool for the parts of compensation that are easy to hand-wave and hard to compare: benefits, 401(k) match, paid leave, PTO, stipends, and worst-case medical cost.
No backend. No accounts. Offers live in your browser, and share links encode the current comparison into the URL.
Base salary is easy to compare. The rest gets fuzzy fast.
OfferLens gives you a side-by-side view of direct compensation, equity vesting, health-plan costs, employer benefits, and a few “quality of life” values so you can reason through offers without building another spreadsheet from scratch.

- Offer data is stored in your browser's
localStorage. - There is no backend database and no account system.
- There is no analytics code in this repo.
- Share links encode the full offer state into the URL hash (
#s=...). The hash is plaintext base64 JSON. Anyone with the link can read the compensation details, so treat a share URL like a screenshot of your offer letter. - The app currently loads fonts from Google Fonts. If you want a fully self-contained build, self-host the fonts.

This is a comparison tool, not a payroll model.
- Projections use simple, explainable formulas.
- Equity is modeled with four-year vesting.
- Parental leave and PTO are shown as salary-equivalent values.
- Worst-case medical cost is shown as annual premiums + deductible + remaining OOP risk after deductible.
- Schema version bumps currently reset saved local data instead of migrating it.
