Disclosure: I work on Opennomos.
Every developer has that one browser tab graveyard of half-trusted online tools — a timestamp converter here, a JSON formatter there, each wrapped in three layers of ads and a cookie wall. OpenNomos Json is a small attempt to fix that: a clean, no-nonsense developer toolset that just works, and an ecosystem that actually pays back the people who improve it.
What it is
OpenNomos Json is a collection of community-built developer utilities. Two that ship today:
Timestamp Converter — two-way conversion between seconds, milliseconds, local time and UTC, with automatic s/ms unit detection. No more guessing whether 1700000000 is seconds or milliseconds.
