Co(lab)

Build startups faster with deep work

Stop switching between dozens of tools. Co(lab) is a hybrid web browser + local code editor with integrated AI designed for startup builders who need to move fast.

Ship early, build in public. At Blackboard we already use co(lab) to build Electrobun and co(lab) itself, the Developer Preview is open for brave builders—even while onboarding and a few features are still rough. Download it, kick the tires, and tell us how co(lab) can power your deep work.
