What is boj-archive?

Boj-archive is a public HTML-based snapshot of Baekjoon Online Judge (BOJ) problems, scraped before the acmicpc.net service shuts down in 2026. It delivers a 560MB downloadable archive of 33,828 problems in JSON format, complete with full descriptions, input/output samples, images, difficulty tiers, tags, and stats like accepted counts. Developers get an offline boj internet archive for browsing via a lightweight index or diving into individual problem folders.

Why is it gaining traction?

This boj archive stands out with solved.ac-sourced metadata like precise difficulty levels (Bronze to Ruby) and average solve tries, making it easier to filter challenges than scraping live sites. The single-tar download and relative image paths enable quick local setup without servers, appealing to anyone needing a reliable BOJ adventure camp archive. Its non-commercial, delete-on-request policy builds trust for long-term preservation.

Who should use this?

Competitive programmers in Korea archiving BOJ history for offline practice. Educators building custom algorithm courses from tagged problems. Devs creating indigenous archives boj lopez-style collections or testing solutions without internet.

Verdict

Grab it for a complete BOJ archive if you're in the ecosystem—45 stars and 1.0% credibility score reflect early maturity and thin docs, but the data dump is solid and public-good focused. Worth the download for preservation, less so for production apps.
