I made a free offline-first practice app for certification exams
I made Examplar, a free offline-first web app for practicing certification exams.
I started building it because a lot of exam practice tools either require an account, hide progress behind a platform, or are unclear about where the questions come from. I wanted something simple: open the site, pick an exam, practice, and keep progress locally in the browser.
What it does:
- - runs in the browser
- - works offline after loading
- - requires no signup
- - stores progress locally
- - supports timed exams and study mode
- - supports multiple question types, not just basic multiple choice
- - has an editor/import flow for creating custom exam packs
- - is open source
The first public packs are mostly Microsoft/Azure because that is where I started, but the app itself is meant for certification exams overall. I want to add more vendors and domains over time: cloud, security, networking, AI, and other professional certs.
The study material is based on public exam objectives and official learning documentation. The questions are original and meant to test understanding, not copied from real exams or dumps.
I’d appreciate feedback on the UX, positioning, and which certification areas would be most useful to add next.
