Does anyone have any recommendations for something like Cursor but more open? Cursor's harness is so much faster than anything else I've used that I just can't give it up, using Claude Code feels like being on 0.25x speed. Also I do like the IDE-style UI, being able to highlight code in a file editor and then quickly add that to my chat (Cmd-L) is really nice and much more difficult in CLI based harnesses.
Right now I think GPT 5.6 Luna is by far the most cost effective model, so this change is effectively kicking me off of Cursor.
This, and the keep/undo flow, forking agent sessions (including renaming them)... The UX could be better at places but the core features of what Cursor has (for someone who came from VS Code) is an unbeatable mix. Really would like to find something else.
I did try Kiro which seems to have the same philosophy but it's just not there. Most of the features I like in Cursor are missing.
Some other commenters mentioned that VS Code + Copilot would be better these days. Dunno.
I am also wondering the same thing as OP. Somewhat tangential thought, but I recently realised that what I would really love in an IDE is a "first class" Markdown editing experience, just because most of my day-to-day is managing and writing docs rather than editing code. Cursor has Markdown rendering support of course but it seems to have two implementations, each sort of clunky in their own way. And I want something more WYSIWYG but with Latex / flowchart / etc. support built-in.
OpenKnowledge seems to maybe fill that niche somewhat (it also supports annotating Markdown with comments to feed into an agent), and has agent integration within the GUI, but one killer feature that seems to be missing is Remote SSH support (short of hosting its web server on the remote and having the IDE live in the browser).
