Insomnia was a favorite REST and GraphQL client for years, until a mandatory account and cloud login pushed a wave of developers to look for something else. If you want to send API requests without signing in or syncing your work to someone's cloud, you have good options in 2026. This guide covers the best Insomnia alternatives, starting with the lightest.

Why Developers Are Leaving Insomnia#

The trigger was a change to how Insomnia handles accounts: recent versions push you to log in and store data in the cloud, where older versions let you work fully offline and local. For developers who treat API requests as code that lives in the repo, that was the wrong direction. The alternatives below all answer the same question: can I send requests without an account and keep my work local?

What to Look For#

Offline and local: Works without signing in, data stays on your machine
Git-friendly: Requests stored as plain files you can commit and review
Open source: Auditable, and not at the mercy of one vendor's roadmap
Free: No paywall on the core send-a-request workflow
Fits your editor: Bonus if it lives where you already work

The Best Insomnia Alternatives#

1. .http files (VS Code REST Client, IntelliJ, httpyac)#

The lightest option is not an app at all. A .http file is a plain-text request you keep next to your code:

### Get a user
GET https://api.example.com/users/1
Authorization: Bearer {{token}}

### Create a user
POST https://api.example.com/users
Content-Type: application/json

{ "name": "Ada" }

### Get a user
GET https://api.example.com/users/1
Authorization: Bearer {{token}}

### Create a user
POST https://api.example.com/users
Content-Type: application/json

{ "name": "Ada" }

The same format is supported by the VS Code REST Client extension, IntelliJ IDEA's built-in HTTP client, and the httpyac CLI. Because it is just a file, it commits to git, reviews in a pull request, and needs no account. For most day-to-day request testing, this is the closest thing to a no-friction Insomnia replacement.

2. Bruno#

Bruno is the alternative most ex-Insomnia users land on. It is open source, offline-first, and stores collections as plain text files in your repo, so requests live alongside the code and version with it. No account, no forced cloud.

3. Hoppscotch#

Hoppscotch is an open-source, browser-based client (also self-hostable). Good if you want a fast UI without installing an app, and the self-host option keeps data in your control.

4. Postman#

Postman is the incumbent and the most feature-complete, with collections, environments, mocks, and team features. The caveat is that it leans hard on accounts and the cloud, the same direction people are leaving Insomnia for. Worth it if you need the ecosystem; skip it if avoiding cloud login is the whole point.

5. Thunder Client#

A lightweight client that runs as a VS Code extension. Handy if you want a UI without leaving the editor, though some features sit behind a paid tier.

6. curl and HTTPie#

For scripting and quick checks, the command line still wins. curl is everywhere, and HTTPie adds a friendlier syntax and readable output. Both are trivial to drop into scripts and CI.

Comparison#

Tool	Type	Offline	Git-friendly	Account needed	Open source
.http files	Editor / CLI	Yes	Yes	No	Yes (tools)
Bruno	Desktop app	Yes	Yes	No	Yes
Hoppscotch	Web / self-host	Partial	Limited	No	Yes
Postman	Desktop / cloud	Limited	Limited	Yes	No
Thunder Client	VS Code extension	Yes	Limited	Some features	No
curl / HTTPie	CLI	Yes	Yes	No	Yes

How to Choose#

Want the lightest, git-native option: .http files in VS Code or IntelliJ
Want a full GUI without the cloud: Bruno
Want browser-based or self-hosted: Hoppscotch
Need the full ecosystem and team features: Postman
Scripting and CI: curl or HTTPie

A Request Is Only Half the Job#

These tools all do the same core thing: build a request and send it once. What none of them do is tell you when that endpoint breaks in production at 3am. That is monitoring, not testing, and it is a different tool.

This is where ObserveOne fits alongside whichever client you pick. ObserveOne's API checks take the same request you just built (method, headers, body) plus assertions on status code, response time, and body, then run it on a schedule from multiple regions and alert you when it fails. Build the request in your editor; monitor it with ObserveOne.
