Depends

Should I use Plane?

Project management for teams and AI agents. Plan, track, and ship with Projects, Wiki, and AI. Available on cloud, self-hosted, and air-gapped. - plane.so

· 1 month ago

Buy if you're an engineering-heavy or self-hosting team that wants an open-source Jira/Linear alternative. Skip it if you want zero-maintenance SaaS or can't patch fast — 2026 brought several high-severity CVEs.

Confidence

Medium. Based on ~14 usable public sources; many search results matched the 2023 film 'Plane' and were discarded. No pricing numbers or verifiable customer names appeared in usable evidence.

Gotchas - check before you buy

high

Self-hosting means you own patching; six CVEs surfaced, several high severity

medium

Open-source vs paid feature split unclear; verify what self-host license includes

medium

Guess: air-gapped installs may lag cloud security fixes unless you pull updates yourself

low

Per-seat pricing page exists but no prices surfaced; confirm total cost before rollout
