BracketView

BracketView is a privacy-first JSON workspace for developers who need to inspect API responses, configs, webhook bodies, and logs without juggling multiple tools.

Paste JSON into the browser and explore it across multiple views: text, tree, graph, node cards, and a nested table. Use search to find keys and values in large nested structures, and switch into Dual mode to keep the editor on one side and your chosen view on the other. Formatting and validation are built in: beautify (format) or minify JSON, and catch common syntax problems as you type with line and column feedback.

When you need more than visual inspection, BracketView includes querying and comparison tools. Run JSONPath queries (for example, $.store.book[*].author) and use jq for precise filtering. Diff compares two JSON documents side by side to spot added, removed, and changed values. You can also validate against JSON Schema or an OpenAPI definition and generate types from an example payload.

BracketView’s core tools run locally in your browser and don’t require an account for the free workspace. Pricing is freemium: Free ($0 forever) covers viewer, formatter, validator, node and table views, JSONPath, jq, diff, and schema tools. Pro ($3/month or $2.25/month billed annually) is optional for larger uploads, longer snapshot links, and AI features without a monthly cap; Node, Table, and the nine UI languages remain free.

Is BracketView free to use without an account?

Yes—core workspace tools are free with no signup required, including the viewer, formatter, validator, node and table views, JSONPath, jq, diff, and schema tools.

Does BracketView upload my JSON when I view, format, validate, or query it?

No for core tools. Viewing, formatting, validation, JSONPath, and jq run in your browser. Optional server features like AI, snapshot links, and Webhook Tester use server functionality only when you choose them.

What JSON views can I use in BracketView?

You can open the same payload as text, tree, graph, node cards, or a nested table. Stats and JQ are available alongside those views, and Dual mode keeps the editor on the left while you browse a view on the right.

How do I validate JSON online?

Paste your JSON and use the real-time validator. It highlights issues like bracket mismatches, trailing commas, and unquoted keys as you type, and reports the first problem with line and column details.

Can I query JSON without writing code?

Yes—use JSONPath for structured matches and jq for filtering and extraction. If you want a plain-English workflow, the AI query assistant can generate a jq filter, but AI features are optional.

What are the upload limits and plan differences?

Free web uploads are up to 5 MB. Pro increases web uploads to 50 MB and adds Performance Mode for large payloads. Free stays available for Node and Table views and for all nine UI languages.
