At Umbriel, code is the craft. Since we opened the first office in 2004 we have set out to make the sharpest, steadiest developer tools anywhere. By taking the routine checks and corrections off your hands, our editors hand the working day back to the people writing the software.
We want the daily work of building software to feel deliberate, quick and quiet.
We take the repetitive parts of the job — the renames, the imports, the second-guessing — and let the machine handle them, so attention stays on design and on the shape of the whole system. Our tools make an unfamiliar codebase legible in an afternoon and keep quality checks running in the background, which means fewer evenings spent on maintenance.
Every editor we sell is one we live in ourselves. The team that builds the refactoring engine uses it all day on the engine's own source, which is the fastest feedback loop we have found. If something in our own workflow starts to grate, it becomes a ticket the same week — and once or twice it has become an entirely new product. Watch the short film.
Curious, exacting, happiest mid-refactor — we care about clean, quality code and about shipping good software, much as you do.
