M3E Canvas VS Rune (IDE)
Verdict BUY IT BUY IT
The Reality Real, MIT-licensed, and verifiable firsthand — there's a live working demo at lnkiai.github.io/m3e-canvas with no backend and no signup required, so the core claim (sketch a screen, get a prompt) can be checked directly rather than taken on faith. GitHub engagement looks organic: 636 forks on 6,270 stars (~10%) is proportional, not the near-zero-fork pattern seen on the one confirmed-inflated repo in the same discovery batch. Independent trend-tracking sites (thedailycommit.in, explaingit.com) picked it up too, suggesting real organic attention rather than only self-promotion. Confirmed real via a substantial, genuine Hacker News discussion (199 points, 63 comments) directly on the official open-sourcing announcement — real community engagement, not just a vendor claim. The GitHub repository (unstablebuild/rune) is real and confirmed GPLv3 licensed, matching the announcement exactly. Worth noting for anyone searching: 'Rune' is also the name of two unrelated projects — Google's experimental security-research language and the separate 'rune-rs' Rust scripting language — this is neither of those.
SHORT ANSWER
M3E Canvas: M3E Canvas is a real, free, MIT-licensed browser tool for sketching Material 3 UI screens into AI-coding prompts — you can verify it works yourself via its live no-signup demo.
Rune (IDE): Rune (by unstablebuild) is a real IDE that was genuinely open-sourced under GPLv3, confirmed by real Hacker News discussion and a matching GitHub license — distinct from two unrelated same-named projects.
