Better JSON Formatter
Smart JSON formatter: auto-fix, URL decode & copy nodes
What it does
JSON Formatter is a browser-based tool built for developers who work with JSON daily. It auto-fixes malformed JSON instead of just erroring out. The search lets you filter through large payloads instantly - highlighting matching keys and values as you type. You can copy any nested object directly from the tree without manually selecting text. It also accepts URL-encoded JSON as input, and supports URL params so you can pre-load it with JSON from your own workflow or scripts.

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…
