Swastik Codes vs Postman

Postman is the API platform most developers learned on, and Swastik Codes was built to be familiar to those developers. Both tools use collections, environments, {{variables}}, pre-request and test scripts written against the pm.* API, a collection runner, mock servers and monitors. The differences are in where the tools run, how they are licensed and priced, and how far each one goes beyond the basics. This page compares them as of October 2026. Postman facts come from Postman's own website and Learning Center; Swastik Codes facts come from the product itself.

Short verdict. Choose Postman if you need a macOS desktop app today, need to call localhost or private-network services, rely on Postman-specific services such as the Postman API Network, Spec Hub governance or the Postman CLI in CI, or your company has already standardised on it. Choose Swastik Codes if you want a browser-based client that opens your existing Postman collections and scripts, covers HTTP, GraphQL, WebSocket, Socket.IO, SSE, gRPC, MQTT and MCP in one place, and includes team features such as forks, pull requests and reviews without a paid plan.

At a glance

Where Postman is the better fit

Postman is a mature platform, and that shows in places that matter to larger organisations.

• Local and private networks. Postman's desktop app and its desktop agent can send requests to localhost and private networks. The Swastik Codes web app sends requests through the swastik.codes server, which refuses loopback and private addresses for security. The Swastik Codes desktop app for Windows and Linux sends requests from your own machine, so it reaches localhost and VPN hosts too; on macOS, Postman's desktop app (or another local client) is the practical choice until the Mac version ships.
• Ecosystem. The Postman API Network, the Postman CLI, Newman, Flows deployed as cloud endpoints, and a large catalogue of integrations are mature and widely documented.
• Established vendor. Postman offers Team and Enterprise plans with vendor support, which some companies require in procurement.
• AI requests. Postman's request types include AI requests to models, which Swastik Codes does not offer.

If your team already pays for Postman and is happy with it, there is no reason to move.

Where Swastik Codes fits

Swastik Codes is a good match if you want Postman-style workflows in the browser without a paid plan.

• It reads your existing work. Postman Collection v2.0, v2.1 and v3 files, environments, globals and data dumps import directly, and scripts that use pm.test, pm.expect, pm.environment, pm.sendRequest and pm.execution.setNextRequest run unchanged. swc.* is Swastik Codes' name for the same API; the importer can convert scripts to it, and exporting to Postman writes pm.* back. See importing a Postman collection.
• Every protocol in one client. Alongside REST you get a GraphQL client with schema introspection, a WebSocket client, a Socket.IO client for v2, v3 and v4 servers, an SSE client, a gRPC client with proto upload or server reflection, an MQTT client for MQTT 3.1.1 and 5, and an MCP client for Model Context Protocol servers.
• Team review built in. Fork a collection, change it, and open a pull request that teammates review and approve before merging, with optional merge checks such as a required number of approvals. Comments, @mentions and version history are part of collaboration.
• Testing beyond single requests. Run a whole collection with data-driven iterations, run load tests with ramp-up, spike and peak profiles, and schedule monitors with email or webhook alerts.
• Specs and docs. Edit OpenAPI and AsyncAPI definitions with linting in API design, generate or re-sync a collection from a spec, and publish API documentation for a collection.
• Free to use. There are no paid plans today. Create an account and everything above is available.

Feature notes worth knowing

Script compatibility. Swastik Codes runs scripts in a sandboxed JavaScript engine with the swc.* API, which is the same object as Postman's pm.*, chai-style assertions such as swc.response.to.have.status(200) and to.have.jsonSchema(), legacy postman.* and tests[] globals, and built-in modules such as lodash, moment, crypto-js, uuid, ajv, tv4, xml2js and cheerio via require. Most real-world Postman test suites run unchanged. If something does not, the console shows the script error, and we would like to hear about it.

Code generation. The code panel produces 30 snippet variants, from cURL and HTTPie to Python, Go, Java, C#, PHP, Rust and more. See code generation.

Authorization. API key, Bearer, JWT, Basic, Digest, OAuth 1.0, OAuth 2.0 (authorization code with PKCE, implicit, password, client credentials, refresh), Hawk, AWS Signature v4, NTLM, Akamai EdgeGrid and ASAP are supported. See authorization.

Moving from Postman

Moving takes a few minutes for most teams:

1. In Postman, export your collections (Collection v2.1 is the safest choice) and environments, or export a full data dump.
2. In Swastik Codes, open Import and drop in the files. Format is detected automatically.
3. Sign in, pick an environment and send a request. Run the collection in the runner to check that your tests pass.

The step-by-step guides are How to import a Postman collection and Migrating from Postman. Nothing stops you from keeping both tools: Swastik Codes also exports Postman Collection v2.1, so you can move work back.

Frequently asked questions

Can Swastik Codes run my Postman test scripts?

Yes, in most cases. Swastik Codes implements the documented pm.* sandbox API under its own name swc.*, with pm.* kept as the same object, plus chai expect, sendRequest, execution.setNextRequest and skipRequest, the visualizer and the common built-in libraries. Postman-specific services that exist only inside Postman's cloud are not available.

Can Swastik Codes call APIs on localhost?

Yes. Like Postman's desktop agent, Swastik Codes has a local bridge: run swc bridge and switch it on in the web app, and requests run on your machine. The desktop app for Windows or Linux does the same for every protocol. Without either, browser requests are sent by our server, which blocks loopback and private addresses.

Is Swastik Codes affiliated with Postman?

No. Swastik Codes is an independent product by Shwastik Tech Solutions Pvt Ltd. It works with Postman's publicly documented collection formats and script API so that you can bring your work with you. Postman is a trademark of its owner.

What does Swastik Codes cost?

Nothing today. There are no paid plans. You can create a free account and use every feature.
