5 Awesome Proxyscotch Alternatives

Proxyscotch is a lightweight, open-source CORS proxy server built by the Hoppscotch team. If you've ever tried to test an API from the browser and hit a wall of CORS errors, Proxyscotch solves that by routing your requests through a proxy that adds the right headers. It's free, simple, and designed to work seamlessly with Hoppscotch.

Since Proxyscotch is fully open source, you can self-host it on Sliplane for just €9/month with one-click deployment, no server setup required. Check out our easy deploy guide to get started in minutes.

But maybe Proxyscotch isn't the right fit for your use case. Maybe you need more features like caching, edge distribution, or a managed service that doesn't require any setup. Let's look at 5 awesome alternatives!

1. CORS Anywhere

CORS Anywhere is the original open-source CORS proxy, and by far the most well-known one with over 9,400 stars on GitHub. It's a Node.js reverse proxy that adds CORS headers to any request you send through it, letting you bypass browser restrictions without modifying the target API.

• Features: Reverse proxy with automatic CORS headers, configurable origin whitelisting and blacklisting, rate limiting, custom request header injection, support for all HTTP methods, HTTPS support, and intermediate proxy configuration.
• Why You Should Use It: If you want a battle-tested, no-frills CORS proxy you can self-host and fully control, CORS Anywhere is the go-to. The codebase is simple enough to understand in an afternoon, and it runs on any Node.js environment. With 9,400+ GitHub stars and years of production use, it's proven and reliable.
• Why Not: The project hasn't been actively maintained since 2021, and the public demo server has been severely rate-limited since then. You'll need to self-host it for any real use, and you're on your own if you hit bugs. It also lacks modern features like caching, edge distribution, or a web dashboard.
• Pricing: Completely free and open source (MIT license). No hosted service available, so you need to self-host. Running it on Sliplane costs €9/month.

2. Corsfix

Corsfix is a modern CORS proxy that goes well beyond simple header injection. It offers features like domain allowlisting, response caching, secrets management, and a global CDN with over 99.9% uptime. The project went open source in July 2025, so you can now self-host it too.

• Features: All HTTP methods (GET, POST, PUT, PATCH, DELETE), response caching with configurable TTL, secret credential management, domain allowlisting, support for JSON/HTML/images/video, global infrastructure with low latency, and an interactive playground for testing.
• Why You Should Use It: If you need a production-ready CORS proxy with advanced features like caching and secrets management, Corsfix delivers. The managed service handles infrastructure for you, and since it's now open source, you have the option to self-host if you prefer full control. The playground makes it easy to test before committing.
• Why Not: The free tier is gone, so you'll need a paid plan starting at $5/month for the managed service. Self-hosting requires more setup than simpler proxies like Proxyscotch. The open-source version may not include all features of the managed service.
• Pricing: Hobby at $5/month (60 RPM, 25 GB bandwidth); Growth at $9/month (120 RPM, 100 GB); Scale at $19/month (180 RPM, 500 GB); Lite at $29/year (text content only, 600 RPM shared). Self-hosting is free (open source).

3. CorsProxy.io

CorsProxy.io is a managed CORS proxy built for production workloads. With 330+ edge locations across 125+ countries and a median added latency of just 25ms, it's one of the most performant options available. Companies like Uniswap and Figma use it in production.

• Features: Global CDN with 330+ edge locations, edge caching with configurable TTL, web scraping and content extraction, custom request/response headers, format conversion (CSV/XML/RSS to JSON), 99.9% uptime SLA, free development tier with no account required, and support for localhost environments.
• Why You Should Use It: If you need a zero-setup, production-grade CORS proxy with global edge distribution, CorsProxy.io is hard to beat. The free tier is generous for development (10,000 requests/month), and the paid plans scale well. You don't need to manage any infrastructure, and the edge network means your users get fast responses everywhere.
• Why Not: It's a proprietary, fully managed service with no self-hosting option. The free tier is limited to development environments (localhost, CodePen, etc.), so you'll need a paid plan for production. Pricing can add up for high-traffic applications compared to self-hosting.
• Pricing: Free (10,000 req/month, dev only); Hobby at $5/month (250,000 req/month, 2 domains); Production at $29/month (unlimited requests, 20 domains, web scraping); Scale at $99/month (no rate limits, no domain limits, SLA). 14-day money-back guarantee.

4. CORS.SH

CORS.SH is an open-source CORS proxy service built with TypeScript that focuses on simplicity and reliability. Just prefix your API URL with https://proxy.cors.sh/ and add your API key, and you're done. The project is fully open source on GitHub under the MIT license.

• Features: Simple URL-prefix usage pattern, API key authentication via x-cors-api-key header, support for all content types, up to 6 MB per request, no hourly rate limits on paid plans, free tier for qualifying open-source projects, and a playground forked from Hoppscotch for testing.
• Why You Should Use It: If you want a managed CORS proxy that's also fully open source, CORS.SH is a solid pick. The pricing is straightforward and affordable ($3-4/month), and the generous free tier for open-source projects (1 million requests/month) is a nice touch. The TypeScript codebase makes it easy to understand and contribute to.
• Why Not: The managed service has lower request limits compared to CorsProxy.io (500K/month on paid plans vs. unlimited). The project has fewer GitHub stars (~230) and a smaller community than CORS Anywhere. Self-hosting requires setting up the full TypeScript/Node.js stack.
• Pricing: Free for open-source projects (1M req/month, 5 MB/req, needs 5+ GitHub stars); Monthly at $4/month (500K req/month, 6 MB/req); Annual at $3/month; Enterprise at $499/year (10M req/month, 1 TB bandwidth).

5. CORS.lol

CORS.lol is the simplest CORS proxy on this list. It's open source, free to use, and works by just prepending https://api.cors.lol/?url= to any URL. No account, no API key, no setup. If you just want CORS issues to go away with minimal effort, this is it.

• Features: Dead-simple URL-prefix usage (no API key needed for free tier), open-source codebase on GitHub, supports all HTTP methods, free tier for non-commercial use, lifetime Pro plan for commercial use, and no rate limits on the Pro plan.
• Why You Should Use It: If you need a quick, no-fuss CORS proxy for development or prototyping, CORS.lol is the fastest path to "it just works." There's no account creation, no API key management, and the $35 lifetime Pro plan is a steal compared to monthly subscriptions. The open-source nature means you can self-host if needed.
• Why Not: The free tier has rate limits and is restricted to non-commercial use. There's no SLA, no edge network, and no advanced features like caching or credential management. The service is primarily designed for development, not production workloads. Documentation is minimal.
• Pricing: Free (rate-limited, non-commercial only); Pro at $35 one-time lifetime payment (no rate limits, commercial use, larger file sizes, technical support). Self-hosting is free (open source).

Conclusion

Each tool fills a different gap: CORS Anywhere for a self-hosted classic, Corsfix for production workloads with caching, CorsProxy.io for global edge performance, CORS.SH for an affordable open-source managed service, and CORS.lol for zero-friction prototyping.

Proxyscotch remains a great choice if you use Hoppscotch and want a lightweight proxy you fully control. But if you need more features, global distribution, or a managed service, one of these alternatives might be a better fit.
