jsonbolt is a hardware-accelerated JSON viewer. Drop a 1 GB JSON file on it. The tree is open before your finger leaves the trackpad.
Same machine. Same file. Same goal: open it and let me search. We waited so you don't have to. Times measured to first usable tree on a M2 Pro / 32 GB.
Drop a 1 GB API dump and start clicking. No load bar, no freeze.
Virtualized tree renders just the visible rows. Scrolling stays at native refresh rate, no matter how deep the document goes.
Find every order over $1,000 across 12M records in a second.
SIMD-accelerated regex, basic and key-value search capable of processing files at 1 GB/s and generating tens of millions of matches per second. No other tool comes close.
Skip the curl, skip the jq. Paste the URL.
Drop any JSON endpoint in and the response lands in the tree like a local file. Save auth headers for the APIs you keep hitting.
Open it once. Watch it fill up.
jsonbolt re-reads the file as it grows. New rows show up at the bottom, your scroll holds, your search keeps highlighting. Mostly for NDJSON logs that won't sit still while you read them.
Highlight what you want. Pick a format.
Pick a subtree and save it out as XML or CSV. Where you'd normally reach for jq plus a one-liner — except you see what you're grabbing before you commit.
Stay in flow. Slow tools break it.
A SIMD parser that runs bytes through AVX2. Tree layout, scrolling hit a WGPU pipeline. Open multi-gigabyte files in seconds.
Same JSON engine you click on, now in your terminal. Inspect huge JSON files, search by key, value, JSONPath, or type, and extract exact results — without dumping the whole document into your prompt, script, or CI log. Purpose-built for JSON, so scripts and agents can ask smaller, sharper questions.
