HAHoppscotch is a free, open-source API development platform with 78,000 GitHub stars and it’s replacing Postman for thousands of developers worldwide. In this short, we break down exactly what it does and why teams are ditching their paid subscriptions for it.
Hoppscotch supports REST, GraphQL, WebSocket, MQTT, and Server-Sent Events all in one clean interface. You get environment variables, request collections, pre-request scripts, post-request tests, and full team collaboration — no installation needed, runs straight in your browser.
It also ships as a desktop app for Windows, Mac, and Linux, works offline, and can be fully self-hosted on your own server with Docker.
Postman charges up to $49 per user per month for these features. Hoppscotch is completely free.

SAAPIs often work in Postman but fail in the browser due to browser-enforced restrictions like CORS, authentication differences, or missing headers.
1️⃣ CORS (Most Common Reason)
Browsers enforce Cross-Origin Resource Sharing (CORS).
• If frontend → backend are on different domains
• Browser blocks the request unless server allows it
👉 Postman doesn’t enforce CORS → request succeeds
👉 Browser enforces CORS → request fails
2️⃣ Missing / Different Headers
Postman often adds headers automatically:
• Authorization
• Content-Type
• Accept
In browsers:
• These headers may be missing or restricted
👉 API may reject the request
3️⃣ Authentication Issues
• Postman → manually add tokens
Browser → depends on:
• Cookies
• Local storage
• Session handling
👉 Common issues:
• Expired tokens
• Missing cookies
• Incorrect auth flow
4️⃣ Preflight Requests (OPTIONS)
Browsers send a preflight OPTIONS request before actual calls.
• Server must respond correctly
• If not → browser blocks the request
👉 Postman skips this → works fine
5️⃣ HTTPS vs HTTP
• Browser enforces strict security rules
• Mixed content (HTTP API on HTTPS site) is blocked
👉 Postman doesn’t enforce this strictly
6️⃣ CSRF Protection
• Browsers include cookies automatically
• Servers may require CSRF tokens
👉 Missing CSRF token → request rejected
7️⃣ Rate Limiting / IP Blocking
• Browser requests come from user IP
• Postman may use different environment
👉 Server may block or throttle browser traffic
8️⃣ Payload / Encoding Differences
• JSON formatting issues
• Incorrect encoding
• Form-data vs raw JSON mismatch
👉 Works in Postman, fails in browser
9️⃣ Proxy / Network Differences
• Browser → corporate proxy / VPN
• Postman → different network config
👉 Requests behave differently
🔟 Caching / Service Workers
• Browser may cache responses
• Service workers may intercept requests
👉 Leads to unexpected behaviour
The issue usually comes down to browser-enforced constraints like CORS, preflight checks, or authentication differences—not the API itself.

If an API works in Postman but fails in the browser, it’s usually due to environment differences (headers, CORS, auth, cookies, etc.)
.
✅ If API works in Postman but fails in Browser:
1️⃣ CORS issue (Most common)
Browser blocks cross-origin requests, Postman doesn’t. Backend must allow frontend origin.
2️⃣ Preflight (OPTIONS) not handled
Browser sends an OPTIONS request first. If server doesn’t allow it → request fails.
3️⃣ Missing Headers
Authorization, Content-Type, or custom headers may not be sent from frontend properly.
4️⃣ Authentication issue
Token or cookies may not be attached in browser request.
5️⃣ HTTPS vs HTTP (Mixed Content)
Browser blocks HTTP APIs when frontend is running on HTTPS.
6️⃣ CSRF Protection
Backend may require CSRF token for browser requests.
7️⃣ Cookie / SameSite policy
Browser enforces cookie security rules, Postman doesn’t.
8️⃣ Wrong API URL / Environment
Frontend may be pointing to different environment.
.
🔍 How I debug:
Open Browser DevTools → Network tab → compare request with Postman → identify difference → fix backend or frontend config.
