ide-lsp returned the same `unavailable` error whether no server was running or a running server didn't implement the request, so the UI said no language server was available, and Invoke Inline Completion said no language server provides inline completion, while jdtls was running fine (it doesn't implement textDocument/inlineCompletion). When servers are running but none supports the feature, the error now names them ("jdtls doesn't support inline completion"), and every explicit action shares one message helper: Invoke Inline Completion, go to declaration / implementation / type declaration, quick documentation, parameter info, rename, reformat, intention actions, highlight usages, call / type hierarchy, find usages, safe delete and workspace symbols. With no server running it still says no language server is available. Background requests while typing stay silent.
Fixes #186

Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
Build
