What it does
An online tool website for comparing two JSONs and visually displaying differences, designed to help you quickly locate the differences in JSON data.
Compare two JSON files online with this semantic JSON diff tool. Semantic comparison understands data structure, not just text — spot value changes, type mismatches, and missing properties with full key-path context.
A semantic JSON diff tool that understands structure — not just text. Detect value changes, type mismatches, and missing properties with full key-path context. A client-side JSON comparison tool that parses structure semantically — not just text. Fast, private, and built for developers. Color-coded highlights for every JSON difference: green for additions, red for deletions, yellow for value changes. Full key-path reporting for nested objects. Efficient recursive algorithms compare JSON objects with thousands of keys in under a second. No server round-trip, no loading spinners. All JSON parsing and diffing happens in your browser using JavaScript. Your data never leaves your device unless…from comparejson.com

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
