Project mention: 300+ languages doesn't mean what you think: three tiers of code understanding | dev.to | 2026-08-08
I am not the first person to look at this. aider evaluated stack-graphs and went with tree-sitter tags plus PageRank instead (#534). So did OpenHands (#742) and SWE-agent (#38). Three serious teams reached the same conclusion: too much work, unmaintained upstream, not worth it.
