Postman vs Insomnia vs Hoppscotch: Which API Client Is Best in 2024?

Open any developer’s laptop and you’ll likely find an API client pinned to the taskbar. For years, that slot belonged almost exclusively to Postman. Then Insomnia arrived with a sleeker interface, and Hoppscotch showed up as a lightweight, open-source alternative that runs in a browser tab.

In 2024, the choice is genuinely harder—and the stakes are higher. Postman laid off staff in 2023 and pivoted toward enterprise sales. Insomnia changed hands when Kong acquired it in 2019 and has since pushed users toward paid cloud features. Hoppscotch raised funding and grew into a full-featured tool. Each product now has a distinct philosophy, pricing model, and audience. Here’s how they compare.

The Short Version

  • Postman is the most feature-complete option, best for teams that need collaboration, governance, and API lifecycle management. It’s also the heaviest and most commercial.
  • Insomnia offers a clean, focused experience for individual developers and small teams, with strong GraphQL and gRPC support. Its recent versions have pushed cloud sync and paid tiers.
  • Hoppscotch is the lightweight, open-source choice. It’s fast, browser-based, and free for most use cases, but its enterprise and collaboration features are less mature.

Postman: The Incumbent

Postman started in 2012 as a Chrome extension and grew into a platform used by more than 20 million developers, according to the company. That scale is both its strength and its weakness.

What works well: Postman does nearly everything. You get REST, GraphQL, WebSocket, gRPC, and SOAP support. Collections, environments, and variables are mature and well-documented. The Collection Runner handles automated test sequences, and Newman (Postman’s CLI tool) lets you run collections in CI/CD pipelines. Mock servers, API documentation, and monitors are built in. If your team needs a shared workspace with role-based access, Postman delivers it.

Where it falls short: The app has grown heavy. Startup times and memory usage are common complaints, especially on older machines. More importantly, Postman’s free tier has tightened. In 2023, the company limited free plan usage and pushed collaboration features behind paid plans. The desktop app now requires an account for most workflows, and the cloud-first design means your data lives on Postman’s servers unless you configure otherwise. Enterprise pricing is custom and generally expensive.

Postman is the right call if you work on a large team that needs governance, shared collections, and API lifecycle tooling—and if your organization is willing to pay for it.

Insomnia: The Focused Contender

Insomnia began as a side project and earned a following for its clean design and developer-friendly defaults. Kong acquired it in 2019, and the tool has since evolved toward a hybrid of local and cloud workflows.

What works well: Insomnia feels faster and less cluttered than Postman. It handles REST, GraphQL, gRPC, and WebSocket requests, and its GraphQL support is particularly strong—schema introspection and autocomplete work smoothly. The request builder is intuitive, and environment variables are easy to manage. For individual developers, the free tier covers most day-to-day needs, including local storage of requests without an account.

Where it falls short: Insomnia’s trajectory has frustrated some longtime users. Recent major versions pushed account creation and cloud sync more aggressively, and some features that were once free moved behind the paid “Insomnia Plus” or enterprise tiers. The plugin ecosystem, while useful, is smaller than Postman’s. Team collaboration features exist but feel less mature. And because Kong owns it, there’s a reasonable question about how tightly the tool will integrate with Kong’s commercial API gateway products over time.

Insomnia suits solo developers and small teams who want a polished, fast client without the weight of Postman—and who are comfortable with its cloud-leaning direction.

Hoppscotch: The Open-Source Upstart

Hoppscotch (formerly Postwoman) is the youngest of the three, and it takes a different approach: run in the browser, stay lightweight, and keep the core open source.

What works well: Hoppscotch loads almost instantly. Because it’s a progressive web app, you can use it from any browser without installing anything, and a desktop app is available for those who want it. It supports REST, GraphQL, WebSocket, SSE, and MQTT. The interface is minimal and fast. The open-source core (available on GitHub) means you can self-host it, which matters for teams with data residency or security requirements. The free tier is generous, and pricing for paid plans is transparent and modest compared to the competition.

Where it falls short: Hoppscotch’s collaboration and governance features lag behind Postman. Collection management is functional but less polished, and advanced testing and automation are thinner. The ecosystem—plugins, integrations, community collections—is smaller. Browser-based tools also raise questions for some security teams, though self-hosting addresses that. For complex enterprise workflows, you’ll likely hit limits.

Hoppscotch is ideal for individual developers, students, open-source contributors, and privacy-conscious teams that want a fast, free, self-hostable client.

Head-to-Head Comparison

Feature Postman Insomnia Hoppscotch
Protocols REST, GraphQL, gRPC, WebSocket, SOAP REST, GraphQL, gRPC, WebSocket REST, GraphQL, WebSocket, SSE, MQTT
Free tier Limited Generous for individuals Very generous
Open source No Partially (some components) Yes (core)
Self-hosting Enterprise only No Yes
Collaboration Best-in-class Good Basic
Performance Heavy Light Lightest
CI/CD automation Strong (Newman) Moderate Basic

How to Choose

The decision comes down to your context, not a universal winner.

Choose Postman if you’re on a team of five or more, need shared workspaces, API documentation, and automated testing in CI, and have budget for paid plans. It remains the safest choice for enterprise environments.

Choose Insomnia if you’re an individual developer or part of a small team that values speed and a clean interface, works heavily with GraphQL, and doesn’t need deep enterprise governance.

Choose Hoppscotch if you want a free, fast, open-source tool, need to self-host for compliance reasons, or work primarily on smaller projects where heavyweight collaboration features are unnecessary.

Many developers keep two installed—Postman for team projects, Hoppscotch for quick one-off requests. That’s a reasonable strategy, and it costs nothing to try all three before committing.

The Takeaway

There’s no single best API client in 2024—only the best fit for your workflow. Postman wins on features and team collaboration at the cost of weight and price. Insomnia wins on focus and speed but has drifted toward paid cloud features. Hoppscotch wins on openness and performance but trails on enterprise tooling. Evaluate against your team size, budget, security requirements, and the protocols you actually use, then pick the tool that gets out of your way.
