The Dev Tools hub is the broader umbrella for Ai2Done's engineering utilities. Where the JSON / CSS / Format hubs each focus on a single language, the Dev Tools hub collects them into a single navigation surface so a backend engineer or SRE can do their full day's "quick format / validate / inspect" workflow from one tab.
The headline utilities are formatters for JSON, XML, SQL and YAML. Each is built around a TinyGo-compiled Wasm engine, which means parse / reflow / minify happen entirely inside your browser. For an SRE this matters: the kind of payloads you copy out of a production log — auth tokens, customer PII, internal config — would be an actual incident if they were posted to a third-party formatter that logged content. Ai2Done's tools structurally cannot leak because there is no server-side path.
Beyond formatters, the hub serves as the navigation hub for adjacent utilities we add over time: file inspectors, sample-file generators, regex testers, time-zone converters. Each tool is purpose-built and small enough to load instantly; the design language follows the macOS-inspired aesthetic shared across Ai2Done so the cognitive overhead of switching between tools is minimal.
Heavy users include backend engineers (formatting API responses while debugging), data engineers (inspecting JSON / YAML configs and schema), SREs (parsing logs in 2am incidents), and platform engineers (validating IaC templates). The shared privacy guarantee — nothing leaves your device — applies to every tool in the hub.
For a single-language deep dive, the JSON Tools, CSS Tools and Format Tools hubs each focus their navigation more tightly. The Sample Files hub provides useful test inputs (well-formed examples of every common format), which pairs naturally with the formatters in this hub when you are building a parser or fuzz-testing a pipeline.
