Tooly is for developers who need quick ways to inspect, transform, and compare data while coding. Its JSON tools format input and show it in a searchable tree, with filters for locating specific keys and values. It also includes data-conversion tools, a regex tester, a diff tool for comparing text, time-conversion utilities, and list tools, plus a JWT decoder and Base64 encoder and decoder. Tooly runs in a browser, requires no signup, and processes data locally, making it useful for routine checks without sending pasted content to a server.
