An Istanbul software collective making free, well-crafted tools for the Flutter ecosystem — no algorithms, no tracking, no lock-in.
DevOpen is an Istanbul-based, open-source software collective. We build in the open and ship under the MIT license — no algorithms deciding what you see, no tracking, no lock-in. Code you can read, fork and trust.
Our home is the Flutter / Dart ecosystem: one codebase, six platforms, from mobile to desktop. We obsess over craft — fast, accessible, thoughtfully designed apps that hand control back to the people using them.
Mobile, design and web — three skill sets that complete each other.
