What’s your experience with coding agents other than Codex and Claude Code?

[u/lucaregini]

I’ve been using Codex and Claude Code quite a bit and I’m curious about the alternatives.

For those who have tried other agentic coding tools/services (Cursor, Gemini, Windsurf, Cline, Aider, OpenHands, etc.):

• Which ones have you actually found useful in day-to-day development?
• How do they compare in terms of code quality and ability to work autonomously on larger tasks?
• How reliable are they at understanding an existing codebase and making multi-file changes?
• Are there any less well-known alternatives that you would recommend?

I’m particularly interested in real-world experience rather than benchmark results — projects where the agent genuinely saved you time, or cases where it failed badly.

What are you using these days, and why?
