Requestly has indeed shifted to a more restricted model over time. While the core remains **open-source** on GitHub (requestly/requestly) and you can still use many features for free or self-host parts of it, the cloud-synced features, unlimited rules/mocks, team collaboration, and some advanced modifications now push toward paid plans (as seen on their pricing page). This is a common evolution for freemium dev tools. Here are some solid **similar tools** that focus on being unrestricted, fully open-source, or truly free forever with no artificial limits on core interception/modification features: ### Strong open-source alternatives (browser extensions or desktop apps) - **Inssman** A fully open-source Chrome/Firefox extension specifically for modifying HTTP requests and responses. Features: Custom rules to modify headers, change responses, block requests, redirects, custom HTML/CSS/JS/JSON injection, logging. No paid tiers or restrictions mentioned — completely free and open-source. GitHub: [https://github.com/vvmgev/Inssman](https://github.com/vvmgev/Inssman) Chrome Web Store: Search for “Inssman: Open-Source: Modify HTTP Request”. - **HTTP Toolkit** Excellent open-source desktop app (with browser integration via extensions) for intercepting, viewing, debugging, and mocking HTTP(S) traffic. It works system-wide or per-browser, supports request/response modification, rules, breakpoints, and injecting custom responses/scripts. Fully free for most use cases, open-source core, no hard limits on rules or modifications (some advanced team/cloud features are paid, but local usage is unrestricted). Highly regarded as a modern Charles/Fiddler alternative. Website: [https://httptoolkit.com](https://httptoolkit.com) - **Tamper Dev** (formerly Tampermonkey-like for requests, but focused on interception) Chrome extension that lets you intercept, inspect, and edit live HTTP requests/responses. Very powerful for on-the-fly modifications. Free, no mentioned restrictions. ### Other good open-source options (more API client + some interception) If you’re okay with a tool that’s stronger on API testing but still offers interception/modification: - **Hoppscotch** (formerly Postwoman) — Fully open-source, lightweight API client with request interception in browser contexts. - **Bruno** — Open-source, Git-friendly API client (local files, no cloud required). - **Insomnia** (core is open-source) — Great for API work, with some proxy/interception capabilities. ### Quick comparison table for interception focus | Tool | Type | Fully Open-Source | No Usage Limits | Modification Types | Desktop or Browser | | --- | --- | --- | --- | --- | --- | | Inssman | Browser extension | Yes | Yes | Headers, response, block, redirect, inject | Browser | | HTTP Toolkit | Desktop + browser | Core yes | Yes (local) | Full proxy: mock, rewrite, breakpoints | Desktop/Browser | | Request Interceptor | Browser extension | Partial? | Yes | Redirect/block, headers, query params | Browser | | Easy Interceptor | Browser extension | Yes | Yes | Overwrite response for XHR/fetch | Browser | Many users who got frustrated with Requestly’s limits have switched to **Inssman** or **HTTP Toolkit** for pure interception work without nagging upgrades. If you tell more about your main use case (e.g., header mods only, API mocking, script injection, mobile debugging), I can narrow it down further! --- _[View the full topic](https://onehack.st/t/any-alternative-to-requestly/319742)._
