Every tool included. No install required.
From JSON transforms to visual chains — the complete API workflow, right in your browser. No account, ever.
Transform Playground
Filter and reshape JSON with JSONPath or JavaScript. Live output, AI expression suggest, and a dedicated workspace.
Method-driven theming
Every HTTP method has its own color. GET is emerald, POST is blue, DELETE is red — your API is always scannable.
JSON Compare
Side-by-side JSON diff with change-only tree view. Seed from any response and spot regressions instantly.
JSON Visualize
Interactive node graph from JSON, YAML, or CSV. Zoom, search, and rotate layouts to explore complex payloads.
Shareable request links
Generate a link that pre-loads method, URL, headers, and body. No account, no export — just paste and send.
Dark, light & accent themes
System-aware dark/light mode plus custom accent colors. Persistent across sessions with zero flicker.
Multi-tab workspace
Keep multiple requests open side-by-side. Switch between GET, POST, and DELETE without losing context.
HTTP request builder
Full REST client with params, headers, auth, and body editors — everything in one focused workspace.
Command palette
⌘K to search requests, history, collections, and actions. Navigate the app without touching the mouse.
Collections
Organize requests into folders. Drag, drop, reorder, duplicate, and export as Postman v2.1.
Environment variables
Use {{BASE_URL}} and {{API_KEY}} across all requests. Switch between dev, staging, and prod in one click.
Import anything
Postman v2.1, Insomnia, OpenAPI 3.x, Swagger 2.0, and cURL — drop a file or paste and go.
API Hub
Pre-built provider collections and environments. Import GitHub, OpenAI, Stripe, and more in one click.
Response viewer
Pretty JSON, raw mode, headers, HTML preview, and cookies — all in one panel with color-coded status.
Response actions
Summarize, compare, transform, visualize, copy, and download — every response tool one click away.
Code generation
Live snippets in cURL, fetch, axios, Python, Go, Ruby, Java, and more. Copy-ready with one click.
Request timing waterfall
DNS → TCP → TLS → TTFB → Download breakdown per request. Spot slow hops at a glance.
Why did this fail?
Plain-English diagnosis for 4xx/5xx errors with actionable fixes and AI deep-dive when you need more.
Response assertions
Status, header, and JSONPath tests on responses and chains. Pass/fail badges keep smoke tests visible.
GraphQL
Dedicated query editor with variables and headers. Send GraphQL requests alongside your REST workflow.
WebSocket
Connect, send messages, and inspect the live message log — all without leaving the workspace.
cURL import & export
Paste any curl command to populate fields instantly, or export any request as a copy-paste curl snippet.
Pre/post-request scripts
JavaScript snippets with env.set() for chaining tokens. Syntax check and AI script writer built in.
Visual request chains
Canvas workflow with API nodes, conditions, delays, and display nodes. Run entire flows sequentially.
Zero-code token passing
Draw arrows between nodes. JSONPath maps a response field into the next request's URL, header, or body.
Request history
Last 200 requests auto-saved and searchable by URL or method. Reopen any call in a new tab instantly.
Request health monitor
Per-endpoint success rate and p50 latency in your collection tree. Spot flaky APIs before they break prod.
Zero CORS headaches
All outbound requests route through a server-side proxy. Test any API from the browser without extensions.
100% local data
IndexedDB only — no account, no cloud sync. Your requests and secrets never leave your device.
