Open-Source API Gateway

Protect your API from attacks.
No SDK. No code changes.

Backport is an API gateway that lets you transform responses, mock APIs, and add custom security rules — without changing your backend code. Point your clients to Backport. That's it.

# 1. Create your account
Sign up at backport.in
# 2. Generate an API key from the dashboard
Your key: bk_live_xxxxxxxxxxxx

Live Demo

See the WAF in action

Select an attack type, send a request, and watch Backport block it before it reaches your server.

Request
Request Preview
GET /api/users?id=1' OR '1'='1' --
X-API-Key: bk_live_xxxxxxxxxxxx

Attempt to extract all user records by injecting SQL into the query parameter.

Response
Backport Response

Select an attack type and send a request to see the response

Simulated DemoThis simulates how Backport's WAF processes real requests. Try all 5 attack types to see the difference.

Three steps. That's it.

No complex setup. No SDK installation. No backend changes.

1

Create an account

Sign up with your email. You will get access to a dashboard where you can manage API keys and view analytics.

2

Generate an API key

Create a unique API key from your dashboard. This key authenticates all your requests through the proxy.

3

Point your traffic here

Replace your backend URL with the Backport proxy URL in your client code. Add the X-API-Key header. Done.

What makes Backport different

Every feature listed here is real and functional. No vaporware.

Response Transformation

Modify API responses on the fly without touching your backend. Add fields, remove sensitive data, rename keys, or filter response bodies. Set rules by path pattern — no code deployment needed.

API Mocking

Define mock endpoints in your dashboard. When your backend is down or during development, Backport serves your mock responses automatically. No more frontend teams blocked by backend downtime.

Custom WAF Rules

Define your own regex-based firewall rules with per-endpoint control and severity levels.

Webhook Notifications

Get instant alerts on Slack, Discord, or any URL when WAF blocks a request, rate limits are hit, or your backend returns errors. Never miss a security event.

Built-in WAF + Rate Limiting

17 regex patterns covering SQL injection, XSS, path traversal, command injection, LDAP injection, and XXE. Plan-based rate limiting from 100 to 5,000 requests per minute.

Full Analytics Dashboard

Real-time traffic charts, latency heatmaps, slow endpoint detection, threat alerts, and request replay. Export everything as JSON or CSV for your own analysis.

Works with any language

Backport is an HTTP proxy. If your backend speaks HTTP, it works. No SDK needed.

cURL
curl https://backport.in/proxy/users \
  -H "X-API-Key: bk_your_key_here"

Who is this for?

Backport is built for developers who want API protection without the complexity.

Indie developers

You are building an API and need basic protection. You need protection without spending hours configuring nginx rules or deploying complex infrastructure. You want to ship, not do ops.

Small teams

Your team is focused on building features, not managing infrastructure. Backport gives you WAF, rate limiting, and analytics without a dedicated security engineer.

API-first products

If your product exposes an API to third-party developers, you need protection from abuse. Backport gives each client their own API key and usage limits.
