Code · Overlay · Free
Ofradr is an open source coding assistant aimed at live coding, timed assessments, and offline practice. It is not a VS Code fork you rent by the month. Ultra is free. The repo is sunnycodet/ofradr.
Overlay sits on the session you already have — CoderPad, HackerRank, LeetCode, IDE — without a paid plugin.
Point Ultra at a local model when you do not want the prompt to leave the machine.
Copilot-style tools bill per user. Ofradr bills nobody.
Those products are editors. Ofradr is an overlay assistant for situations where you cannot install a marketplace extension — shared pads, locked-down exam browsers, screen-shared interviews.
Because it is open source, you can see that the assistant is a small native binary rather than a 200MB Chromium wrapper.
Unlimited chat means you can iterate on a graph problem for an hour. Unlimited browser mode means a long HackerRank window does not cut you off. That used to be the Ultra upsell.
It is an open source overlay assistant, not a full IDE. For interviews and assessments it replaces paid copilots. For daily editing you may still use an IDE plugin.
Yes. Ultra is free forever. Practice on your own machine and follow site rules.
