Restfox: an offline-first HTTP client that runs in a browser tab or as a desktop app
Offline-First Minimalistic HTTP & Socket Testing Client for the Web & Desktop
At a glance
- What is it?
- Restfox is a Vue-based HTTP, GraphQL and WebSocket testing client distributed as a PWA, an Electron app, a Docker image and native packages. The interesting part is not the request builder but where your data lives, and that is also where the sharpest limits are.
- Who is it for?
- Adopt Restfox if you want an MIT-licensed client you can self-host on port 4004, install from Homebrew, Snap or Scoop, or run as a PWA, and if you are comfortable that the storage model is the product. Do not adopt it if you need a hosted collaboration layer or a shared team workspace, because nothing in the README describes one.
- Can I use it commercially?
- Yes. MIT is a permissive licence: you can use, modify and sell software built on it, as long as you keep its copyright and licence notices.
- Is it still maintained?
- Yes. The repository last received commits 74 days ago.
- What is it written in?
- Mainly Vue, according to GitHub's language statistics.

DEEP OPEN-SOURCE ANALYSIS
The problem Restfox takes on: request history that survives without a server
Most HTTP clients assume a backend. Collections sync to a vendor account, environments live on someone else's disk, and the client stops being useful the moment the network or the vendor does. Restfox inverts that. The README describes it as an offline-first minimalistic HTTP and socket testing client for the web and desktop, and the distribution list backs the claim up: a PWA at restfox.dev, an Electron desktop build, a Docker image on port 4004, and native packages through Homebrew, Snap and Scoop. Nothing in that list requires an account. The target user is an engineer who tests REST endpoints, GraphQL queries and WebSocket connections, wants request history and environment variables to persist locally, and does not want a second SaaS dependency in the toolchain. The MIT licence matters here too, because it means the client can be forked or embedded without a commercial conversation.
What the repository layout tells you about the architecture
Restfox is a monorepo. The README's compile instructions move between packages/ui, packages/web-standalone and an electron package, which means the same Vue front end is the product in every distribution. The desktop build wraps it in Electron with electron-builder and the Forge makers for deb, rpm, squirrel, zip and flatpak. The web-standalone build is the same UI packaged to be served by a small Node process, which is what the Docker image runs. That single-codebase approach is the reason the feature set is identical whether you open the PWA or the Snap package, and it is also the reason the browser build has the same storage constraints as the desktop build rather than a server-side database. The editor layer is CodeMirror, and the README keeps a long list of @codemirror packages to upgrade together, which is a hint that the request and response editing surface is assembled from many small modules rather than one editor component.
Installing Restfox on macOS, Ubuntu, Windows or Docker
The installation surface is unusually wide for a project of this scope. On macOS the README gives brew install restfox. On Ubuntu and distributions that support snap it gives sudo snap install restfox. On Windows it gives scoop bucket add extras followed by scoop install restfox. Precompiled RPM, DEB and NuPKG binaries are attached to the releases page. The Docker route is a single command: docker run --name Restfox -d -p 4004:4004 flawiddsouza/restfox:0.40.0, and the README also documents docker-compose up -d, a custom port form using docker-compose -p 5000:4004 up -d, and pinning a version with RESTFOX_VERSION=0.40.0 docker-compose up -d. If you would rather not pull the published image, you build the web-standalone bundle yourself: clone the repository, cd Restfox/packages/ui, run npm i and npm run build-web-standalone, then cd ../web-standalone, npm i and npm start. That last command serves Restfox on port 4004 by default, and the README shows PORT=5040 npm start to change it. The Dockerfile build follows the same path, then docker build -t restfox:xx . and docker run -d -p:4004:4004 restfox:xx.
Plugins, environment variables and response history are the features that carry the tool
The README's screenshots section is the closest thing to a feature list, and it names three areas: response history, environment variables, and plugins. Response history is the offline-first payoff. Because nothing round-trips to a server, the history you accumulate is yours and stays queryable without a login. Environment variables are shown across two screenshots, which suggests both a variable editor and a substitution step in the request pipeline, though the README does not document the substitution syntax, so treat that as something to confirm in the docs site rather than assume. Plugins get a dedicated video link in the README, and the screenshots show plugin configuration screens. The README does not specify the plugin API surface, what lifecycle hooks exist, or whether plugins can mutate requests before they are sent. That is the single biggest documentation gap in the material supplied here, and it is the first thing to check if plugin extensibility is why you are considering Restfox at all.
Where Restfox stops being the right tool
Offline-first is a storage decision, and storage decisions have edges. If two engineers need to share a collection, the README describes no sync, no team workspace and no hosted collection store. The Docker image serves the UI on port 4004, which makes it a shared front end, not a shared data layer: the README does not state that the container persists or centralises request data, so do not read the Docker path as a collaboration feature. The second edge is the browser distribution. A PWA stores its data in the browser profile, so clearing site data, switching browsers or moving machines takes your request history with it. The desktop build avoids that, but it is still a local store with no documented export or import format in the material here. Third, the README documents no CI runner, no command-line mode and no way to execute a saved collection from a script. If your requirement is running a request suite in a pipeline, Restfox is a manual client and nothing in the README suggests otherwise.
How Restfox differs from Postman and from curl plus a shell script
Compare against Postman first, because that is the default choice for most teams. Postman is account-centric: collections, environments and history live in a hosted workspace, and the client is a view onto that workspace. Restfox is the opposite arrangement. The application is the store. That difference decides the trade: Postman gives you sharing and a cloud history that follows you between machines, Restfox gives you a client that keeps working with no account, no network and no vendor. If your team's review process depends on someone opening a shared collection link, Restfox does not participate in it. The second alternative is curl plus a shell script or a Makefile. That approach is fully scriptable, lives in version control next to the code, and has no GUI at all. Restfox wins on discoverability: response history, an environment variable editor and a CodeMirror-based body editor are things a shell script does not give you for free. It loses on automation, because a script can run in CI and a desktop client cannot. Pick Restfox when a human is driving the requests, and pick scripts when a machine is.
Maintenance, release cadence and what the MIT licence actually buys you
The release history in the supplied material shows v0.40.0 in July 2025, v0.39.0 in July 2025 and v0.38.0 in June 2025, so roughly monthly tagged releases across that window, with the repository last pushed in July 2026 and not archived. That is a project still being worked on, though the version numbers are pre-1.0, which is worth factoring into an adoption decision: minor releases can carry behaviour changes. Upgrade cost depends on how you installed it. Homebrew, Snap and Scoop users get whatever the package manager serves. Docker users pin explicitly, and the README supports that with RESTFOX_VERSION=0.40.0 docker-compose up -d, so a version bump is a one-line change. Source builders carry the most: the README lists a long npm i command to move the CodeMirror packages forward together and a second one for the Electron and Forge toolchain, which means dependency drift is a real maintenance task rather than a background concern. The MIT licence permits commercial use, modification and redistribution, and imposes no copyleft obligation on your own code. It also means the project carries no warranty, and none of this is legal advice; if you plan to redistribute a modified Restfox inside a product, have counsel read the licence text rather than this paragraph.
Editorial conclusion
Adopt Restfox if you want an MIT-licensed client you can self-host on port 4004, install from Homebrew, Snap or Scoop, or run as a PWA, and if you are comfortable that the storage model is the product. Do not adopt it if you need a hosted collaboration layer or a shared team workspace, because nothing in the README describes one. Before committing, verify two things yourself: whether the plugin API exposes the request hooks your workflow needs, and whether your environment variables file is excluded from whatever backup or sync path touches the app data directory.
