Open source software development - ide & tools
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. Repoly tracks 14 open-source IDE tools, each scored nightly from its repository activity and ranked by that score alone. code-server leads at 100/100 with 110 commits in the last 90 days and 80k stars, followed by Langfuse (98) and Coder (97). 8 of the 14 score 70 or above, 11 publish a Docker image, and the median health is 87. MIT is the most common licence, carried by 5 of them. The score weighs commits in the last 90 days, release recency, stars, archive status and Docker support; a low number means low measurable activity, not low quality, so a finished, stable tool can legitimately sit lower down.

How the IDE tools compare
code-server edges Langfuse 100 to 98, and most of the difference is stars: 80k stars against 37k stars. Langfuse is the busier codebase, though, with 2,186 commits in 90 days to 110.
The most recent release is code-server v4.144.0, published yesterday. RStudio Server and Azimutt publish no tagged releases, which costs up to 25 of the 100 points. Azimutt and Atheos score under 40, so check recent activity before adopting them. By stack, Nodejs (6), Go (2) and Java (2) are the most common. code-server, Langfuse, JupyterLab and 5 more are permissively licensed; Coder, Eclipse Che, Hopp and 2 more are copyleft. RepoFlow is source-available rather than open source, which limits commercial reuse. RepoFlow is not hosted on a forge Repoly can read, so it has no measured score yet.
Software Development - IDE & Tools: common questions
What is the best open source IDE tool?
By Repoly's GitHub health score, code-server at 100/100 (110 commits in 90 days, v4.144.0 from yesterday). Langfuse is next at 98; code-server's lead comes mostly from stars. The score measures maintenance, not features, so shortlist the top few and try them.
Which IDE tools are the most actively developed?
Lowdefy (3,208 commits in 90 days), Langfuse (2,186 commits in 90 days) and Coder (1,933 commits in 90 days). Commit activity is 35 of the 100 health points, the largest single term.
Which IDE tools can I run in Docker?
11 of 14 publish a Docker image or Compose file, led by code-server, Langfuse, Coder, JupyterLab, Lowdefy and 6 more.
Which IDE tools have a permissive licence?
8 of 14: code-server (MIT), Langfuse (MIT), JupyterLab (BSD-3-Clause), Lowdefy (Apache-2.0), LiveCodes (MIT) and 3 more. 5 are copyleft.
