I KEPT LOSING MY PLACE

I've been reading manga and manhwa for years. Hundreds of titles across dozens of sites. And I kept losing track of them.

Browser bookmarks got wiped. Notes apps got abandoned. Tracking websites wanted me to sign up, manually search for every title, and update my progress by hand every single time I read a chapter. I just wanted something that sits in my browser, figures out what I'm reading, and remembers where I stopped.

So I built it. Checkpoint does exactly one thing well: it keeps track of what you're reading so you don't have to. It's free, it's open source, and your data never leaves your machine.

— Built by a reader who got tired of losing chapter 47 of three different series in the same week

THE GOOD STUFF

CORE

ONE CLICK. ANY SITE. DONE.

Open the side panel, hit the + button, and Checkpoint figures out the rest. It reads page metadata to detect the title and chapter number — no manual entry, no copy-pasting URLs. It works on MangaDex, Webtoon, Tapas, MangaPlus, raw scanlation sites, and basically anything with a chapter number in the page.

And if a site uses a weird title? Add an alternative name once, and Checkpoint recognizes it forever.

ORGANIZE

ORGANIZE IT YOUR WAY

Create custom tags with auto-assigned colors. Sort your library into Reading, Completed, Plan to Read, or make your own lists. Then filter across everything with a tri-state system that actually makes sense: click once for AND (green), twice for OR (blue), three times to Exclude (red). Combine tags, genres, and format tabs to find exactly what you’re looking for.

ALERTS

KNOW WHEN NEW CHAPTERS DROP

Enable notifications on any title and Checkpoint checks AniList and MangaDex every 60 minutes in the background. When a new chapter is out, you’ll know. No more refreshing release calendars or checking five different sites.

Fair warning: notification accuracy depends on API data, which isn’t always perfect for ongoing series. But it catches most updates.

CSV Bulk Import

Got a spreadsheet? Upload a CSV and Checkpoint batch-matches your titles against AniList and MangaDex with confidence scoring. Review matches, confirm the good ones, fix the rest.

Backup & Restore

Full JSON export of your entire library. Import it on another machine. Your data, portable and yours.

Side Panel UI

Lives in Chrome’s side panel — always one click away while you’re reading. No new tabs, no popups, no context switching.

Alternative Names

‘Solo Leveling’ on one site, ‘Na Honjaman Level-Up’ on another. Checkpoint remembers all the names for the same title.

100% Local

No accounts. No servers. No tracking. Everything lives in Chrome’s local storage on your machine.

Open Source

MIT licensed. Read the code, fork it, contribute. The whole thing is on GitHub.
