For many of us, Postman has been the go-to tool API Client and testing tool for years. Postman has been evolving, and experiencing a lot of changes, some of which have been controversial, and made many, including you, to look for a Postman replacement. This article lists the best Postman alternatives for sending requests to different types of APIs, including SOAP, Restful, or GraphQL. We continue to update this article with the latest information about the offered features. Please reach out to us via our contact page for any correction or addition of a new tool.
Limits of Postman’s Free Plan
Before diving into the alternatives, it’s important to know the limits of Postman’s free plan:
- API Creation: The free plan restricts users to creating only three APIs within a team. This can be limiting for projects that need a larger number of APIs, particularly if your project involves multiple microservices.
- Collection Runner Runs: One of the most significant constraints is the limit of 25 runs per month using the local collection runner. This limitation might become a bottleneck if your project demands frequent and comprehensive testing, requiring you to either upgrade to a paid plan or find alternative solutions.
- API Calls and Mock Server Calls: The free plan allows for a maximum of 1,000 API calls and 1,000 mock server calls per month. For projects with higher traffic or more complex testing needs, these limits might prove restrictive, forcing users to upgrade or explore other tools with more generous quotas.
- Flows: Users are limited to five flows under the free plan, which could restrict the complexity of the workflows you can create and automate within Postman.
- Team Collaboration: Collaboration is limited to three users per team on the free plan. If your team expands beyond this, you’ll need to upgrade to a paid plan to continue collaborative work effectively.

Thunder Client
Website: thunderclient.com | Last Reviewed on: 2023-12-13
Postman’s slow app and confusing UI led Ranga Vadhineni, the creator of Thunder Client, to build a simple and fast HTTP client. Rather than offering a web app, he decided to build a VScode extension to eliminate the need for switching between apps. Thunder Client aims to be a lightweight extension that offers a simple UI and fast experience. As of today (Dec 2023), the extension has over 3 million downloads and 3.5 (out of 5) stars on the VScode marketplace.

Author’s Note on Thunder Client
If you’re a VSCode user looking to send requests without context switching, Thunder Client is a good choice, assuming you’re happy with the 50 requests per collection limit. The VSCode extension also means you can only collaborate with your colleagues if they’re also using VSCode as well.
httpYac
Website: httpyac.github.io | Last reviewed on: 2024-07-21
httpYac
provides a way to create and send HTTP requests using a text-based file format that is superset of RFC 7230, a tool for those who prefer text-based tools over GUI-based tools. At the moment httpYac is available as a command-line tool and via two VSCode extensions: VS Code extension to create and execute requests and httpBook for documentation of requests in a Jupyter Notebook Format.
The goal [of httpYac] is to create a simple, free and extensible development tool that follows known standards if possible. For example, for the description language of the requests, the specification mostly repeats RFC 7230 with several extensions intended for easier requests composing and editing.
Supported Features
Feature | Details |
---|---|
API Support | Restful, GraphQL, Soap and gRPC |
Authorization | OAuth2, AWS, Basic, Digest, SSL Client Certificate and Bearer Token |

- You can organize multiple API services using collections and focus on one at a time.
- You can embed customizable random values to your request
- A great echo system of open-source plugins to extend Insomnia’s capabilities
Insomnia Cons
- You cannot write tests for standard requests. Testing capabilities of Insomnia are only available to Design Documents (API specs written in Open API format).
- Does not support folders
Author’s Note on Insomnia
I’ve been using Insomnia on and off for a few years now. It’s a great tool, and I love the simplicity of the tool. That said, it won’t work for more advanced scenarios. For me, it was only a tool for sending requests quickly. If you’re among users who need a simple tool for sending requests, Insomnia is a great choice. Also, if you’re moving away from Postman because of the retirement of ScratchPad, it worth to read the next paragraph first before you make a decision.
Insomnium, the fork of Insomnia
Website: archgpt.dev/insomnium | Last Reviewed on: 2023-10-19
Source: Insomnium Github repo
To understand why Insomnium exists today, I should tell you a backstory.
The release of Insomnia 8 made a lot of noise. Overnight, and without any prior communication (to the best of my knowledge), Insomnia users were asked to sign up for an account and move their data to the Cloud; the Offline Anonymous Scratchpad experience that many Insomnia users relied on to get their job done became unavailable.
In a sense, Insomnium is a community response to the latest Insomnia product update that forces account creation w/o warning. Source: Insomnium Github repo
Marco Palladino, CTO and co-founder of Kong, commented in a Github issue that the company roadmap, and technical and business challenges, made them move in this direction. A few weeks later, Kong, the company that acquired Insomnia, announced that they had bought back the Local Projects to 8.3.0. This was in response to the feedback Kong received from the community.
With that backstory out of the way, Insomnium, as it is stated in the Github repo, is a fork of Kong/insomnia at 2023.5.8, the last commit before compulsory account login was introduced. In a sense, Insomnium is a community response to the latest product update that forces account creation w/o warning.
But Matt, you didn’t tell us the story behind the name Insomnium. Well, a picture speaks a thousand words!
Source: Insomnium Github repo
In a nutshell, Insomnium is open-source and free, maintained by a group of contributors, is fully offline and does not come with any tracking or communication to external servers. Insomnia users can follow the instructions to migrate their data to Insomnium. In terms of features, Insomnium offers the same set of features as Insomnia at the time of fork.

Hoppscotch’s Cons
- Folders do not support variables, auth etc, they’re purely for organizing requests
- No collection runner, you cannot run all requests in a folder with a single click
- The cloud version offers team members, but without access control over folders or requests
Author’s Note on Hoppscotch
Hoppscotch has seen a lot of improvements since it was first released, thanks to an active community of contributors and a 3mil seed funding from OSS Capital in 2021. Today, the company offers paid plans for enterprise customers. As of today, don’t expect more than an API Client form Hoppscotch, for sending basic HTTP requests, Hoppscotch is a great tool. That said, you might experience limits as you start using it for more advanced scenarios. For example, lack of collection runner and inability to set variables for folders might be a deal-breaker for some users.
Rapid API
Website: paw.cloud | Last reviewed on: 2024-05-16
Rapid API (formerly known as Paw) has been a Mac-only app for a long time. In Feb 2021, Rapid API announced that they had acquired Paw and announced the availability of cross-platform Paw applications and a new subscription-based pricing model. It is free for personal and professional use and teams up to 5 users. But if you have a team with more than five users, you have to pay a price that begins at 60 USD per month. It’s still a Mac-only app, and other platforms are not supported yet. Generally, Rapid API doesn’t offer many of the features that Postman offers, but don’t let that disappoint you because Rapid API provides a range of extensions for adding new features. For example, you can use a Faker.js extension to generate and include random data in the request. Rapid API comes with a visual HTTP client and a native macOS interface to describe APIs.
Rapid API’s Pros
- The native Mac app is fast
- Rapid API is extendable using 3rd-party extensions
Rapid API’s Cons
- Does not support other platforms than Mac-OS
- Documentations are not updated and still refer to the app as Paw instead of Rapid API
Postcode

Postcode is another VScode extension for sending HTTP requests. It’s free, open-source and is developed to do one thing, sending HTTP requests. Use Postcode to fire a request (XML, JSON, GraphQL, Form Data or binary) and see the response in a clean UI.
Supported Features
Feature | Details |
---|---|
API Support | Restful, GraphQL, XML |
Request Builder | Query Params, Headers, Payload, Authorization (Only Basic and Bearer Token) |

- You cannot create environments, environment variables or globals. Everything has to be set for each request
Author’s Note on Postcode
Use Postcode for sending HTTP requests, nothing more, nothing less. If you’re looking for a tool to organise your requests, share them with your colleagues or run them in bulk, Postcode is not for you.

Author’s Note on Firecamp
While using Firecamp, I noticed some minor issues in their UX/UI. Although they have improved their User Interface, you may still face some minor bugs. Their documentation is incomplete, and you might encounter a “WORK IN PROGRESS” message when you want to read about a section. It can make it tricky and time-consuming to figure out how things work. Despite these issues, if you are looking for an alternative to Postman that offers a dedicated GUI playground for REST, GraphQL, Websocket, and SocketIO, Firecamp is worth checking out.

Bruno
Website: usebruno.com | Last reviewed on: 2023-11-29
Bruno’s website says they’re Re-Inventing the API Client. It’s an offline-only (with no plans to add cloud sync) API Client that stores requests, environments and collections as plain text files in your local machine using Bru Lang, a domain-specific language, making it easy to version control requests and collaborate with your colleagues. The app is available for Windows, Mac, and Linux, no web version, sorry!
Supported Features
Feature | Details |
---|---|
API Support | Restful and GraphQL for free. GRPC, Websocket, SocketIO, MQTT are available in the Golden edition. |
Request Builder | Rich request builder with support for query params, headers, body, auth, scripting |
Environments | With ability to set environment variables |
Collections | Headers, auth, scripts, tests, docs and client certificates can be set for collection |
Folders | Only for organizing requests, you cannot set variables, auth etc for a folder |
Folder Runner | All requests in a folder can be executed with a single click |
Import | Postman, Insomnia, cURL, Bruno and Open API Spec 3.0 |
Export | As Bruno or Postman collection |
Authorization | Basic, Bearer, Digest and AWS Signature V4 only. No OAuth2 support |
CLI | Install Bru CLI via NPM to run requests from CLI |
Scripting | Javascript supported. Modify request, access response, set variables, send requests or import any NPM package. |
API Testing | Write BDD/TDD style tests or use the low-code Assert feature. |
Storage | Local storage only. No cloud sync. |
Bruno’s Pros
- Free, open source and fast
- Requests can be executed from within Visual Studio Code using the Bru extension. That said, I could not get it to work as I was getting an error saying
command 'extension.runBrunoRequest' not found
.
Bruno’s Cons
- It’s only available as a desktop app
- Certain features like request timeout, cookie jar or disabling SSL verification errors are missing.
- You cannot set variables, headers or auth for a folder.
- If you need a cloud sync, that feature will never be available in Bruno.
- There are some UX issues and rough edges that need to be ironed out. For example, I tried importing a Postman collection, and it failed without giving a clear error. I tried importing the same collection in Insomnia, and it worked fine.
Author’s Note on Bruno
I’ve been using Bruno for a week now, and it’s been a good experience so far. It takes a bit of time to get used to the UI, but once you get used to it, it’s a breeze to use and despite some UX issues and missing features, the app has a lot of potential. If you’re looking for a Postman alternative that’s open source, fast, and has a CLI, Bruno is worth a look.

Jeane Carlos created RecipeUI at Robinhood after witnessing colleagues struggle to use and test internal APIs. RecipeUI is an open-source alternative to Postman that allows JSON to be type-safe and enriched with autocomplete using TypeScript.
Supported Features
Feature | Details |
---|---|
API Support | REST only |
Folders | Only for organization, you cannot set variables, auth etc for a folder |
Request Builder | Query Params, Headers, Body, URL variables and Authorization |
Type safe JSON | Uses TypeScript to make your JSON type-safe |
Auto Complete | Uses TypeScript to allow auto completion of JSON properties |
RecipeUI’s Pros
- It’s cross-platform, lightweight, fast and with a simple and elegant UI
- Uses TypeScript to make your JSON type-safe
- Allows JSON auto-completion by using TypeScript
- It has a builder for URL variables
RecipeUI’s Cons
- Missing variables or authorization for folders
- Missing variables and environments
- No scripting capabilities
- Lack of tabs for switching between requests
Author’s Note on RecipeUI
RecipeUI uses an interesting approach to make your JSON type safe with TypeScript and autocomplete. You can only use it to send HTTP requests to a REST API. No testing and monitoring can be done with it.
curlx
Website: curlx.dev
Curlx, as you might have already guessed, is a supercharged cURL. It’s cURL with the goodness of Postman, for terminal lovers. Shivkanth Bagavathy, the creator of Curlx, has made a great decision (in my opinion) to follow cURL’s syntax so if you know how to use cURL, you’re going to feel at home with Curlx.
History and Collections make CurlX a supercharged cURL. Access past requests using the cx history
command and organize requests into collections using the cx collections
command.
Curlx uses your disk to store the data in JSON format which makes it super easy to version control your data and share it with your colleagues.
Curlx Pros
- Free & open source
- Follows cURL syntax which makes it easy to use
- Local storage
Curlx Cons
- Requires Node.js runtime to work, distributed via NPM

- Supports import of Postman collections
- Provides API mocking capabilities and generates interactive API documentation
Apidog’s Cons
- Having recently completed its beta phase, it’s relatively new to the market, so that it may lack the maturity and community support found in more established tools like Testfully and Postman
- While Apidog focuses on integration-level testing, it might not provide detailed insights into how an API interacts with other system components.
- Despite its user-friendly interface, new users might still face a learning curve with some advanced features or when transitioning from other tools due to differences in workflows or terminologies.
- Accounts for Europe and Global are entirely separate and cannot collaborate across regions
Author’s Note on Apidog
Apidog focuses on integration-level testing and is helpful if you have an API-first approach; it has some valuable features for API mocking and API testing, but it might be a little tricky at first to be able to use its features. If you have a diverse company with colleagues worldwide, using Apidog can be a problem for your company in case of collaboration cause the accounts for Europe and the rest of the world are entirely separated, and they cannot collaborate across regions. With all that said, Apidog is still in its early days and has a long way to go.

SoapUI vs Postman
- Protocol Support
- SoapUI: SoapUI primarily supports SOAP and RESTful APIs. It is particularly strong in environments where detailed SOAP API testing is required, making it a go-to tool for projects heavily reliant on these protocols.
- Postman: Postman supports a wide range of protocols, including REST, GraphQL, SOAP, gRPC, and WebSocket APIs. This versatility makes it a flexible option for developers working across various modern APIs.
- Usability
- SoapUI: The interface is feature-rich but can be complex and overwhelming, especially for beginners. It is better suited for users who need detailed control over their testing environment and can handle a steeper learning curve.
- Postman: Although Postman is known for its user-friendly design, its interface can also feel bloated with features, which might overwhelm users who prefer a simpler, more streamlined tool. While it remains accessible to new users, the large number of options available can make the UI cluttered, requiring some time to navigate efficiently.
- Testing Capabilities
- SoapUI: SoapUI excels in functional, load, and security testing, with advanced automation capabilities through Groovy scripting. It is ideal for complex testing scenarios, especially those involving SOAP services.
- Postman: Postman supports automated testing and scripting (in JavaScript) and is optimized for quick, straightforward API validations. However, it may not offer the same depth as SoapUI in some areas, particularly in load testing and complex scenarios.
- Collaboration
- SoapUI: Collaboration is possible but often requires integration with third-party tools, making it less seamless compared to Postman. It is more geared toward individual or small team use in larger projects.
- Postman: Postman offers collaboration features, including shared workspaces and version control, making it suitable for teams working on shared projects.
- Performance
- SoapUI: Can be resource-intensive, especially during large-scale testing like load tests, which might affect system performance.
- Postman: Generally lighter on system resources, making it a more efficient option for quick tasks. However, its feature-rich interface can sometimes feel sluggish, particularly when dealing with large collections and complex setups.
