Merge Hell

ELI5 — The Vibe Check

Merge hell is when you've been on a feature branch for three weeks, main has moved 400 commits, and now every file has a conflict. You try to merge, git screams, you fix a conflict, three more appear. Hours later, you're questioning your career.

Real Talk

Merge hell describes the compounding difficulty of merging a long-lived branch back into main after significant divergence. Causes include rare rebasing, large refactors on main, missing tests that catch semantic conflicts, and large PRs. Prevented by trunk-based development, small PRs, and frequent rebasing.

When You'll Hear This

"Don't let that branch sit another week — you'll be in merge hell." / "I spent my whole Friday in merge hell."
