CLUSTER BROWSER-FREE-JSON · 7 ENTRIES · EARLIEST ENTRY 2026-03-23

Free browser-based utility suites

This cluster comprises free, browser-based utilities for developers and designers covering JSON formatting, conversions, encoding, image compression, hashing, and password generation, with no signup required. The dated history is too thin to read a shape from – only one dated entry exists before the index start, so the cluster predates the index or its members are undated. Among the traction leaders, toolpocket is listed highest in activity signal, though all three show zero 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 7 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.
