About
OpenSpec is an open-source, spec-driven framework. We help developers plan complex features by creating lightweight spec documents that serve as durable context for their coding agents. With 20k+ GitHub stars, we’re one of the leading spec-driven frameworks, used by thousands of developers and teams to plan and ship with the coding agent of their choice. Our philosophy is simple: keep planning lightweight and iterative, and match how software actually gets built, messy, evolving, and real, without dragging teams into rigid, bureaucratic workflows.
Founders
Tabish Bidiwale· FounderBuilding OpenSpec, the open-source spec-driven framework that makes AI coding reliable on complex work. 20k+ GitHub stars. Previously Team Lead at Q-CTRL. Joined as an early engineer and built the core platform and multiple products from seed to a $113M Series B. While at Q-CTRL, I saw coding agents recreate the same failure mode as human teams: misalignment. Existing tooling wasn’t built for that shift, which led me to building OpenSpec.
