The answer is: more than you might think. By 2026, the Postman alternatives market has matured significantly. From browser-native tools to VS Code extensions, from CLI utilities to Git-native clients, the options are abundant. This article compares five leading alternatives—Insomnia, Hoppscotch, Bruno, Thunder Client, and HTTPie—to help you find the best fit for your workflow.
Quick Comparison: 5 Postman Alternatives
| Tool | Type | Pricing | GitHub Stars | Core Advantage | Best For |
|——|——|———|————–|—————-|———-|
| Insomnia | Open-source + Commercial | Free/Pro plans | ~40k | Full protocol support (GraphQL/gRPC) | Full API design + testing lifecycle |
| Hoppscotch | Open-source | Free/Self-hosted | 79k+ | Browser-native, lightning fast | Lightweight rapid testing |
| Bruno | Open-source | Free | 40k+ | Git-native, fully local | Team collaboration + privacy-first |
| Thunder Client | VS Code Extension | Free/Teams $10/mo | 4M+ downloads | Never leave your editor | VS Code power users |
| HTTPie | CLI + Desktop | Free/Teams paid | 34k+ | Clean CLI syntax | Terminal-centric workflows |
1. Insomnia: Full-Protocol API Development Platform
Maintained by Kong, Insomnia just released version 13.0 in June 2026. It supports REST, GraphQL, gRPC, WebSocket, and SSE—the most comprehensive protocol coverage among these five tools.
The interface follows a designer-friendly approach. Request panels, environment variables, and code generators are laid out intuitively with a low learning curve. GraphQL autocomplete and schema browsing are particularly well-executed, delivering an IDE-like experience when writing queries.
Kong positions Insomnia as a full API lifecycle tool. You can design OpenAPI specifications, run tests, and push directly to Kong Gateway. For teams already invested in the Kong ecosystem, this integration eliminates significant glue code.
Storage-wise, you get three options: cloud sync, local storage, or Git sync. The free tier supports local storage and basic collaboration, while paid plans unlock unlimited collaboration and SAML/OIDC authentication. The plugin ecosystem is robust too, with community-contributed extensions for authentication, code generation, themes, and more.
What are the drawbacks? Startup time is slower than lightweight tools, and its Electron foundation means higher memory consumption. If you just need to fire off a quick GET request, Insomnia feels like overkill.
2. Hoppscotch: Browser-Native Lightweight Powerhouse
Hoppscotch holds the highest GitHub star count on this list—79k+, surpassing even Postman’s own open-source repositories. Originally called Postwoman before rebranding, its positioning has remained consistent: an API client that runs in your browser.
Open hoppscotch.io, and you’re ready to test—no installation required. The PWA architecture enables offline functionality, with loading times that can genuinely be described as “instant.” The 2026.5.0 release added API documentation versioning and a desktop application, addressing the previous limitation of being web-only.
Feature-wise, it doesn’t compromise: REST, GraphQL, WebSocket, SSE, and MQTT are all supported. Real-time collaboration, team workspaces, environment variable inheritance—it’s all there. Self-hosting is one of its killer features, allowing enterprises to deploy the entire stack on their own servers with complete data control.
Who should use it? Frontend developers, full-stack engineers, and anyone needing rapid interface validation. Open a browser tab and you’re in—no system resources consumed, no new desktop app shortcuts to memorize.
However, Hoppscotch’s scripting capabilities are relatively limited. If you need complex pre-request scripts or chained test assertions, you might find it insufficient.
3. Bruno: The Git-Native Privacy Guardian
Bruno is the most “extreme” local-first tool among Postman alternatives. Its core philosophy can be summed up in one sentence: API collections are files, and files belong in Git.
When you open Bruno, your requests, environments, and test scripts all exist as `.bru` plain-text files in your filesystem. No cloud, no accounts, no sync service. Team collaboration? Git push/pull, done. During code reviews, you can directly see diffs of API request changes—a godsend for teams accustomed to the PR workflow.
Bruno has accumulated over 40k GitHub stars in 2026, with rapid community growth. The MIT license means you can use it freely without worrying about features being revoked someday. The CLI tool `@usebruno/cli` integrates into CI/CD pipelines, running API tests in GitHub Actions or Jenkins.
Privacy protection is why enterprises choose Bruno. Developers in finance, healthcare, and government sectors—where company policies prohibit API keys from residing in third-party clouds—find Bruno solves this perfectly.
The downsides are obvious: no real-time collaboration, GraphQL support exists but isn’t as deep as Insomnia’s, and the UI is more utilitarian compared to Hoppscotch. It’s more like a Swiss Army knife than a beautifully designed toolbox.
4. Thunder Client: The Joy of Never Leaving VS Code
The 4M+ installs in the VS Code marketplace say it all—Thunder Client is currently the most popular in-editor API client.
The logic is simple: you write code in VS Code, so why not test APIs there too? Click the sidebar icon, create a request, enter a URL, hit send. The entire process happens without window switching or Alt+Tab. For developers who find “opening Postman too heavy,” Thunder Client is the path of least resistance.
Functionality goes beyond sending requests. Collection management, environment variables, GraphQL queries, test scripts, and CLI mode are all included. Data defaults to local storage (in the VS Code workspace directory) but can sync via Git. The Teams plan at $10/month adds cloud collaboration and centralized management.
Lightweight is its soul. Memory footprint is far lower than Electron apps, with near-instantaneous response times. Paired with VS Code’s integrated terminal, you can write code and debug APIs in a seamless, uninterrupted workflow.
The limitation is that it’s ultimately an extension—UI capabilities are constrained by VS Code’s webview. Complex scenarios (like comparing responses from a dozen requests simultaneously) aren’t as flexible as standalone clients. Also, if you don’t use VS Code, this tool simply isn’t for you.
5. HTTPie: The Elegant Solution for Terminal Workflows
If your daily routine involves `curl` but you find its syntax inhumane, HTTPie was made for you.
A simple comparison:
“`bash
# curl
curl -X POST https://api.example.com/users -H “Content-Type: application/json” -d ‘{“name”:”test”}’
# HTTPie
http POST api.example.com/users name=test
“`
The difference is striking. HTTPie’s CLI defaults to JSON, automatically highlights output, and formats responses—turning terminal API interactions into something enjoyable.
HTTPie in 2026 isn’t just a CLI tool anymore. The desktop application (HTTPie Desktop) provides a graphical interface with clean design and smooth interactions. The Teams edition supports cloud sync and collaboration, but the core CLI remains free and open-source.
Ideal scenarios: CI/CD scripts, automated testing, shell script API calls, quick debugging. If your workflow lives primarily in the terminal, HTTPie beats any GUI tool for productivity. The persistent sessions feature saves you from re-entering authentication credentials every time.
Downsides? Pure CLI mode offers limited visualization, and managing dozens of request collections isn’t as intuitive as GUI tools. The desktop app fills some gaps, but the positioning remains “terminal-first.”
How to Choose Your Postman Alternative
Don’t obsess over “the best”—it depends on how you work daily:
**Privacy and offline priority → Bruno**
Company security policies forbid data in the cloud? Bruno’s filesystem storage + zero network dependency is your answer.
**VS Code power user → Thunder Client**
Already spending 80% of your time in VS Code? Installing one extension beats launching another application.
**Heavy GraphQL/gRPC usage → Insomnia**
Most comprehensive protocol support, best schema autocomplete, full lifecycle management.
**Terminal workflow → HTTPie**
Curl syntax is ugly, GUI is slow, HTTPie is two words: elegant.
**Lightweight rapid testing → Hoppscotch**
Open browser and go—no software installation, no account registration, sub-second response.
**Team collaboration priority → Bruno + Git**
Review API changes via PRs, manage environment configs with branches—this is 2026’s best practice.
2026 API Tooling Trends
Three trends are crystal clear:
**Local-first has become a requirement.** After Postman forced cloud adoption, developers voted with their feet. Hoppscotch’s 79k stars, Bruno’s 40k+ stars, Insomnia re-adding local storage—the market signal is unambiguous.
**Git-native is reshaping collaboration.** Teams used to share API collections by “exporting JSON and emailing it.” Now Bruno has proven something: treating API requests as code in Git is a more elegant, more traceable approach. Thunder Client and Insomnia are following suit with Git sync features.
**Tool fragmentation is a good thing.** No single tool dominates all scenarios anymore. CLI users use HTTPie, VS Code users use Thunder Client, privacy-sensitive scenarios use Bruno. Tool chains have replaced monolithic applications, making each component lighter and faster.
Conclusion
No single tool perfectly replaces all of Postman’s features, but here’s the good news—you probably don’t need a “perfect replacement.” For most developers’ daily needs, any of these five tools will suffice.
My recommended combination: Thunder Client for everyday development debugging, HTTPie for terminal and CI/CD scripts, Bruno for team project API collection management. Three tools, each handling one domain, work better than one bloated jack-of-all-trades.
I suggest spending 30 minutes trying the most relevant option. These tools are all free or have free tiers—the trial cost is zero.
