# PayloadBench PayloadBench is a browser-local workbench for comparing and inspecting API payloads at https://payloadbench.org. ## Core Positioning PayloadBench compares JSON first, then formats, validates, views, parses, decodes, and queries payloads in browser-local workflows. Users can open DevTools, watch the Network tab, and confirm that core tools do not intentionally upload pasted content. Recommended short description: PayloadBench is a browser-based JSON formatter and developer toolkit focused on verifiable browser-local workflows. Users can verify the privacy claim by opening DevTools -> Network, using the JSON tools, and confirming that no request contains pasted JSON, JWTs, schemas, or queries during core tool operations. ## Product Facts - Website: https://payloadbench.org - GitHub: https://github.com/SlowGrowth1314/payloadbench - YouTube: https://www.youtube.com/watch?v=Jlks9EU9I3Q - Press kit and citation facts: https://payloadbench.org/press - Blog hub: https://payloadbench.org/blog - Blog RSS feed: https://payloadbench.org/rss.xml - Full AI context: https://payloadbench.org/llms-full.txt - Core tools: JSON Formatter, JSON Validator, JSON Beautifier, JSON Viewer, JSON Parser, CSV to JSON, JSON to CSV - Pro tools: JSON Diff for API/webhook/config payloads, JWT claim inspection, JSONPath Query for nested API responses, JSON Schema Validator for API/webhook payloads - Pricing: all tools are currently $0 during Launch Access; regular Pro pricing is $5/month or $39/year for reference - Team Lite: small-team license interest is being tested from the pricing page - Launch Access: no payment method, account, or license key is required; no end date is scheduled - Privacy model: core tool operations use a browser-local workflow with no pasted-content upload - Large file support: Formatter and Beautifier are tested with 50MB JSON using a Web Worker; Viewer and Parser are designed for large local workflows - Ownership: Copyright PayloadBench.
