# Resentry > Resentry is a GitHub backup and integrity-monitoring service for individual developers and small teams. We mirror your GitHub repositories to independent servers and detect silent code corruption — force-push, history-rewrite, mass-deletion, and merge-queue diff drift (like the GitHub merge-queue incident on April 23, 2026 that silently corrupted 292 PRs). When something goes wrong, we give you a recovery URL pointing at the last clean snapshot. ## What it does Every connected repository is mirrored as a full bare clone (git clone --mirror), pulled fresh on every push (Pro) or every 15 minutes (Free). After each sync we run integrity checks: force-push detection (git merge-base --is-ancestor), history-rewrite detection (commit-count comparison), mass-deletion detection (git diff --diff-filter=D), and — for Pro — a diff comparison between the GitHub PR's expected additions/deletions/changed-files and what actually landed on the branch. Mismatches greater than 3× ratio or files deleted outside the PR scope trigger a critical alert with a link to the last clean snapshot. ## Pricing - Free: 0 EUR/m, 3 public repositories, 15-minute cron sync, basic integrity check - Pro: 10 EUR/month, unlimited repositories, private repos, real-time webhook sync, full PR-diff integrity comparison, 30-day snapshots, real-time email alerts, GitHub-outage notifications - Team: 25 EUR/month (coming soon), org-wide mirroring, multi-user accounts, Slack/webhook integration, 90-day snapshots with manual pinning, audit log, SLA ## Target users - Solo developers and indie hackers with private SaaS code on GitHub - CTOs and engineering leads of small teams (3-10 people) with GitHub orgs - Any developer who lost work to a force-push, merge-queue bug, or GitHub outage ## Public pages - Landing: https://resentry.de/ - GitHub status / availability: https://resentry.de/status - Sign in with GitHub: https://resentry.de/auth/github ## Tech Open-source-style stack: Go backend, SQLite database with WAL, Tailwind CSS frontend, HTMX for interactivity, Stripe for billing, hosted on Render with persistent disk and daily SQLite backups to Cloudflare R2.
