Rune (IDE)
BUY ITby unstablebuild
Last verified September 12, 2026
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.
Rune is marketed as 'the development environment for pros' — a fast, keyboard-driven IDE combining code, terminals, CLI tools, language intelligence, and AI agents in one composable, multi-workspace environment, now made fully open source.
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.
A real, substantive open-sourcing event with genuine community discussion to back it up, and the license claim checks out exactly against the actual repository. Worth a look if you want a keyboard-driven IDE, just make sure you're looking at unstablebuild's Rune and not one of the two unrelated same-named projects.
Is this Rune the same as Google's Rune language?
No — this is unstablebuild's IDE product. Google has a separate, unrelated experimental language also called Rune, as does the 'rune-rs' Rust scripting project.
