Back in 2012, when Abhinav Asthana released the first version, Postman was a simple HTTP client available as a Chrome extension. Fast forward to today, Postman became a collaboration platform for API development. Postman features include but are not limited to the HTTP client, tools for API testing and API monitoring, mock API servers, and documentation.

Postman offers solutions in different verticals. As a result, it attracts users with various needs. For example, if you are using Postman for API testing, we recommend you to read our api testing tools as we have listed some of the best API testing tools in the market for you. Moreover, we wrote an in-depth article and compared Testfully as an excellent Postman alternative for API testing and monitoring.

This article lists the top 15 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.

Yaak

Website: yaak.app | Pricing: Free | Last reviewed on: 2024-01-22

Yaak, a Postman alternative

Greg, the creator of Yaak, needed a tool to help debug the APIs he was working on, but he wasn’t satisfied with anything on the market so he built his own! Yaak is still in its early days, but it’s a lightweight and cross-platform tool for sending HTTP requests. A robust and elegant UI, support for multiple environments, and folders are some of the features that make Yaak a great choice for sending HTTP requests.

Supported Features

FeatureDetails
API SupportRestful and GraphQL. gRPC and Websocket coming soon!
FoldersOnly for organization, you cannot set variables, auth etc for a folder
Request BuilderQuery Params, Headers, Payload and Authorization
ScriptingNot supported
EnvironmentsWith ability to set environment variables only
Folder RunnerYes, it’s called Batch Send

Yaak’s Pros

  • It’s cross-platform, lightweight, fast and with a simple and elegant UI
  • Requests & folders can be organized using drag and drop

Yaak’s Cons

  • Missing variables or authorization for folders
  • Limited support of authorization schemes
  • No scripting capabilities
  • Lack of tabs for switching between requests

Author’s Note on Yaak

Yaak is still in its early days, yet I found it relatively stable and functional. If you’re looking for a simple and lightweight tool for sending HTTP requests, Yaak is worth a look.

Bruno

Website: usebruno.com | Pricing: Free and Open source, Golden Edition: $12/year. | Last reviewed on: 2023-11-29

Bruno, a Postman HTTP client alternative

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

FeatureDetails
API SupportRestful and GraphQL for free. GRPC, Websocket, SocketIO, MQTT are available in the Golden edition.
Request BuilderRich request builder with support for query params, headers, body, auth, scripting
EnvironmentsWith ability to set environment variables
CollectionsHeaders, auth, scripts, tests, docs and client certificates can be set for collection
FoldersOnly for organizing requests, you cannot set variables, auth etc for a folder
Folder RunnerAll requests in a folder can be executed with a single click
ImportPostman, Insomnia, cURL, Bruno and Open API Spec 3.0
ExportAs Bruno or Postman collection
AuthorizationBasic, Bearer, Digest and AWS Signature V4 only. No OAuth2 support
CLIInstall Bru CLI via NPM to run requests from CLI
ScriptingJavascript supported. Modify request, access response, set variables, send requests or import any NPM package.
API TestingWrite BDD/TDD style tests or use the low-code Assert feature.
StorageLocal 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.

Insomnia

Website: insomnia.rest | Pricing: Free, Paid plans start at $5 (per month/user) | Last reviewed on: 2023-12-05

Insomnina, a Postman HTTP client alternative

Insomnia is a desktop app for Windows, Mac and Linux. You can use it for sending requests to Restful, GraphQL, Web Socket and gRPC APIs and servers. It supports both global and environment variables for reusing variables, but variables cannot be set for folders. When it comes to Authorization, requests in Insomnia can use a great range of authorization options including Basic, Bearer, Digest, OAuth2, and AWS Signature V4. That said, authorization cannot be set for a folder.

Supported Features

FeatureDetails
API SupportRestful, GraphQL, Web Socket and gRPC
Request BuilderRich request builder with support for query params, headers, body, auth but no scripting
EnvironmentsWith ability to set environment variables
FoldersOnly for organizing requests, you cannot set variables, auth etc for a folder
Folder (Collection) RunnerNot Supported
ImportPostman, Insomnia, cURL, Swagger and Open API Spec
ExportAs Insomnia Collection
AuthorizationAll standard authorization schemes available
CLIInstall Inso CLI to run requests from CLI
ScriptingNot supported
API TestingNot supported
StorageLocal and Cloud

Insomnia Pros

  • Simple and easy-to-use UI. Unlike Postman, Insomnia offers a simple and elegant user interface.
  • Insomnia loads faster than Postman and is more responsive than Postman
  • 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 | Pricing: Free and Open source | Last Reviewed on: 2023-10-19

Insomnium, a Postman HTTP client alternative that is free and open-source

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!

The backstory of the name Insomnium

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

Website: hoppscotch.com | Pricing: Free, Paid plans from $19/month | Last Reviewed on: 2023-12-12

Hoppscotch, a Postman HTTP client alternative

Hoppscotch is an open-source API Client with over 57K Github stars, available as a web and desktop app. Hoppscotch offers offline, Cloud and on-prem storage options for your data. It supports Restful, GraphQL and WebSocket APIs via dedicated GUIs rather than one GUI for all types of APIs. A CLI tool is available for integration with CI/CD pipelines.

Supported Features

StorageLocal, Cloud, On-prem

Hoppscotch’s Pros

  • Lightweight with a simple UI
  • Supports most API types and authorization schemes
  • Scripting capabilities are available
  • Supports variables and environments

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.

Paw

Website: paw.cloudPricing: $49

Paw was available as a Mac-only app for a long time with a $49.99 price tag. 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. Out of the box, Paw does not offer many of the features that Postman offers but don’t let that disappoint you because Paw provides a range of extensions for adding new features. For example, we used a Faker.js extension to generate random data and include it in the request.

Paw, a Postman HTTP client alternative

Paw’s Pros

  • The native Mac app is fast
  • Paw is extendable using 3rd-party extensions

Paw’s Cons

  • Does not offer a free plan

Thunder Client

Website: thunderclient.com | Pricing: Free, Paid plans start at $5 (per month/user) | Last Reviewed on: 2023-12-13

Thunder Client, a Postman HTTP client alternative

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. The extension is free to use, with multiple paid plans to lift the limits and unlock advanced features and capabilities.

Supported Features

FeatureDetails
API SupportRestful, GraphQL, XML
Request BuilderQuery Params, Headers, Payload, Authorization and Scripting
EnvironmentsWith ability to set environment variables
CollectionsYes, free plan has 50 requests per collection limit
FoldersCommon headers, scripts, authorization and tests
Folder (Collection) RunnerSupported. Free plan has 30 runs a month limit. Enterprise plan offers unlimited runs
ImportFrom Postman and Insomnia. Requires subscription for importing collections with over 50 requests
ExportAs JSON file
AuthorizationBasic Auth, Bearer, API Key, OAuth2, NTLM, AWS Signature V4
CLIYes, available via subscription
ScriptingBasic scripting capabilities available
API TestingVia a no-code GUI
StorageLocal

Thunder Client’s Pros

  • It’s lightweight and fast as it’s a VScode extension. No need to switch between apps.
  • Offers Git sync, albeit only available via a subscription

Thunder Client’s Cons

  • Only available as a VScode extension
  • The free plan has limits on the number of requests, collections and runs
  • CLI is only available via a subscription
  • Collection Runner has a limit on the number of runs even on some paid plans
  • Missing documentation

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.

Postcode

Postcode, a Postman HTTP client alternative

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

FeatureDetails
API SupportRestful, GraphQL, XML
Request BuilderQuery 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.

Firecamp

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.

curlx

Website: curlx.devPricing: Free

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, a Postman alternative

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
