7 Free Postman Alternatives That Won't Lock Your Collections in the Cloud

In 2023, Postman made a controversial move: it dropped offline support and required users to sync all collections to the cloud. For developers working with sensitive internal APIs, teams under strict data residency requirements, or anyone who prefers to keep their tooling local and under version control, this was a dealbreaker.

The result? A wave of interest in alternatives. And the alternatives have genuinely caught up. Here are seven free tools that cover everything Postman does — without the cloud lock-in.

Why Developers Are Moving Away from Postman

The specific issues that pushed developers to look elsewhere:

• Forced cloud sync: Collections and environments live on Postman's servers by default
• Rate limits on the free tier: Team collaboration features are paywalled
• Workspace complexity: The UI has grown bloated with features many developers don't need
• Pricing changes: Postman has steadily moved features to paid plans

None of these are catastrophic on their own, but together they've made the landscape ready for alternatives.

Bruno — The Git-Native API Client

Bruno is the standout alternative that the developer community has rallied around since Postman's cloud mandate. It stores collections as plain files on your local filesystem — in a format you can commit, diff, review, and merge in Git, just like code.

There's no sync service, no account required, and no cloud. Your API collections live where you put them.

Why Bruno is different:

Every request in Bruno is stored as a .bru file — a plain text format that reads naturally in a code review. A collection is just a folder with .bru files. You can open it, edit it in any text editor, and commit changes like you'd commit anything else.

# Example .bru file
meta {
  name: Get User Profile
  type: http
  seq: 1
}

get {
  url: https://api.example.com/users/{{userId}}
  body: none
  auth: bearer
}

headers {
  Accept: application/json
}

What it does well:

• 100% offline, no account needed
• Collections stored as plain .bru files — perfect for Git
• Supports environments, variables, authentication flows
• GraphQL support
• Pre/post request scripts
• Active development and growing community
• Open-source (MIT)

Limitations:

• Newer tool, some power features still being added
• No built-in cloud sync (intentionally — but means no team sharing without Git)
• Some Postman collection import edge cases

Bruno is the right answer for any team that wants API collections treated as code. If you already use Git for everything else, Bruno fits naturally.

Insomnia — The Closest Postman Experience

Insomnia offers the most Postman-like interface of any alternative. It has a familiar request builder, supports REST, GraphQL, gRPC, and WebSockets, and keeps your data local by default. Kong acquired Insomnia and initially caused controversy with a cloud-sync push, but community pressure and a fork (insomnium) led to the current version restoring local-first storage.

What it does well:

• Rich UI familiar to Postman users
• Supports REST, GraphQL, gRPC, and WebSockets
• Environment variables and request chaining
• Plugin ecosystem
• Local-first storage with optional sync
• Import from Postman collections
• Design and debug workflows for API development

Limitations:

• Sync features require an account
• Past controversy over cloud-sync policy created trust issues
• Heavier than simpler alternatives

Insomnia is the safest migration path for existing Postman users who want to preserve their workflow while gaining local storage.

Hoppscotch — The Open-Source Web Client

Hoppscotch is a browser-based API client that runs entirely in your browser. It's open-source and can be self-hosted, which addresses data residency concerns for organizations that need to keep API requests on their own infrastructure.

What it does well:

• No install needed — runs in any browser
• Self-hostable via Docker
• Real-time WebSocket and SSE support
• GraphQL explorer
• Request collection sharing via links
• Team workspaces on the hosted version
• PWA support for offline use

Limitations:

• Browser-based limits some capabilities
• Collections aren't as naturally git-integrated as Bruno
• The hosted version still involves a third-party service

Hoppscotch is excellent for quick requests, sharing endpoints with teammates, and environments where installing desktop software is inconvenient. The self-hosted option makes it viable for security-conscious teams.

HTTPie — Beautiful HTTP for the Terminal

HTTPie started as a CLI tool that made HTTP requests readable and human-friendly. It has since added a desktop app, but its core strength is still the command-line interface, which produces colored, formatted output by default.

# HTTPie syntax is cleaner than curl
http GET https://api.example.com/users/1 \
  Authorization:"Bearer token123" \
  Accept:application/json

What it does well:

• Intuitive syntax — easier to read than curl
• Syntax-highlighted JSON responses
• Session persistence
• Desktop app with a clean UI
• Offline by default
• Scriptable in shell workflows

Limitations:

• Less suited to complex multi-request workflows
• No built-in collection organization (CLI version)
• The desktop app is less mature than Bruno or Insomnia

HTTPie is ideal for developers who prefer the terminal for exploration and scripting, or teams that want to document API calls in shell scripts that are readable by humans.

Thunder Client — The VS Code-Native Option

Thunder Client is a VS Code extension that brings a lightweight REST client directly into your editor. For developers who rarely leave VS Code, it eliminates the context switch of opening a separate application.

Collections are stored as JSON files in your workspace, which means they can go in version control alongside your code.

What it does well:

• Zero context switch — stays inside VS Code
• Collections stored as local JSON files
• Environment variables and secrets
• GraphQL support
• Import from Postman
• Lightweight and fast

Limitations:

• Tied to VS Code (not standalone)
• Less powerful than full-featured desktop clients
• JSON-based collection format is less readable than Bruno's .bru files

Thunder Client is the right choice if you spend most of your time in VS Code and want your API requests living in the same repo as your code.

REST Client — The Minimalist VS Code Extension

REST Client is a VS Code extension that takes a completely different approach: you write HTTP requests in .http or .rest files using plain HTTP syntax, and execute them with a click or keyboard shortcut.

### Get user profile
GET https://api.example.com/users/1
Authorization: Bearer {{token}}
Accept: application/json

### Create new user
POST https://api.example.com/users
Content-Type: application/json

{
  "name": "Alice",
  "email": "[e-mail]"
}

What it does well:

• Zero overhead — plain text files are the "collection"
• Perfect Git integration — .http files commit naturally
• Variables and environments via .env files
• Response history
• Supports REST, GraphQL, cURL syntax
• No account, no sync, no cloud

Limitations:

• Minimal GUI — no visual collection browser
• Lacks advanced features like pre/post scripts
• VS Code only

REST Client is the most minimal option here, and for many developers that's exactly the point. If your team already documents HTTP calls in README files or wikis, REST Client lets you make those runnable with almost no overhead.

Paw — The Mac-Native Power Tool

Paw (now RapidAPI for Mac) is a native macOS API client with an interface that feels designed for the platform. It has deep macOS integration, a polished UI, and a rich extension ecosystem.

What it does well:

• Native macOS app — fast and well-integrated
• Rich code generation (exports to multiple languages and libraries)
• Dynamic values and request chaining
• Extension ecosystem for custom auth, data manipulation
• Local storage by default

Limitations:

• macOS only — no Windows or Linux
• Paid for full features (free tier is limited)
• RapidAPI acquisition raised some concerns about future direction

Paw is the premium option for macOS developers who want the most native, polished experience. It's particularly strong for generating client code from your API definitions.

Which Should You Choose?

For teams that want API collections in Git: Bruno is the clear answer. Its file-based format is purpose-built for version control.

For individuals migrating from Postman: Insomnia offers the most familiar experience with local-first storage.

For VS Code users who want zero context switching: Thunder Client for a GUI, REST Client for a pure file-based approach.

For terminal-first developers: HTTPie combines readability with scriptability.

For browser-only or self-hosted needs: Hoppscotch with the self-hosted Docker option.

For macOS power users: Paw, if you need advanced code generation and deep platform integration.

The common thread among the best options: your data stays where you put it. In 2025, that's not too much to ask from an API client.
