AI-Generated Review

What is dexter?

Dexter is a Go-built Elixir LSP that indexes huge codebases—like 57k-file monorepos—in seconds without compiling or draining RAM. It powers go-to-definition, references, hovers with docs, renames (even file-moving modules), autocompletion, and lightning formatting via CLI or editor integration. Drop it in VS Code, Neovim, or Zed; CLI handles lookups like `dexter lookup MyApp.Repo get!`.

Why is it gaining traction?

It sidesteps slow compilation-based LSPs by parsing source to SQLite for sub-10ms lookups, auto-reindexing on saves or Git branch switches, and monorepo support out-of-box. Users rave about persistent formatters loading Styler/Phoenix plugins from _build, plus no-reindex branch swaps—huge for Remote's scale. Check the dexter github repo for real-world perf benchmarks.

Who should use this?

Elixir backend devs on umbrellas or monorepos (Oban teams, Phoenix giants, dexter github financial apps) battling laggy tools. Ideal for those scripting refs via CLI or renaming cross-app functions without full rebuilds.

Verdict

Solid pick for large Elixir projects—try the dexter 2 github builds via mise despite 24 stars and 1.0% credibility; docs shine, tests cover edge cases, but await more adoption. Production-viable now if you're over existing LSP pain.
