CLUSTER CODE-LANGUAGES-ONLINE · 11 ENTRIES · EARLIEST ENTRY 2025-02-21

Browser-based online code compilers

This cluster consists of browser-based online compilers and IDEs that let users write, compile, and run code in multiple programming languages. The dated history is too thin to read a shape from, as only one dated entry exists before the index start, and several members have no source date. Traction is led by Mist--Online-compiler and codeblock-compiler-public, both with 1 star, while CODE_CAT_IDE has 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 11 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
