Written by the Apidog team. Apidog is a cloud-synced platform and this page says so; the last section covers what it offers teams that need offline execution and shared work at the same time. Facts were checked on each project's site on September 8, 2026.
"Offline" means two different things when people search for it. Some want a client that never phones home: no account, no sync, requests stored on disk. Others work behind a VPN or an air gap and need tests and mocks to run where the internet cannot reach. Postman is a cloud product with a lightweight local mode, which is why both groups end up here. The tools below are sorted by how completely they work without a connection.
Offline capability compared
| Tool | Account required | Works with no internet | Where requests are stored | Team sharing offline |
|---|---|---|---|---|
| Bruno | No | Yes, fully | .bru files in a folder or repo |
Through Git |
| Yaak | No | Yes, fully | Local database | Export files |
| Restfox | No | Yes, fully | Local | Export files |
| Posting | No | Yes, fully | YAML files | Through Git |
| HTTPie CLI | No | Yes | Sessions on disk | Scripts in Git |
| Insomnia (local projects) | Account for cloud features | Yes for local projects | Local or Git | Through Git |
| Thunder Client | No for free tier | Yes | VS Code extension storage; Git on paid | Paid Git storage |
| Hoppscotch (self-hosted) | Your own instance | Yes, inside your network | Your server | Yes, on your server |
| Postman | Yes | Lightweight mode for local work | Postman cloud; local in lightweight mode | No |
| Apidog | Yes | Desktop apps; self-hosted runner and on-premises edition for private networks | Cloud (global or EU), or on-premises | Yes, on-premises |
1. Bruno: the offline default
Bruno keeps every request as a plain-text .bru file in a folder you choose, needs no account, and never contacts a server. Put the folder in a Git repository and the "sync" is a commit. MIT-licensed; the free client is complete and Pro ($6) adds in-app Git integration. The one caveat: there is no mock server, no docs site, and no live collaboration. See Bruno limitations.
2. Yaak: local-first by design
Yaak states that it does not store, sync, or transmit your data anywhere. It covers REST, GraphQL, gRPC, WebSockets, and SSE, is MIT-licensed, free for personal use, and $79 a year for commercial use. Sharing a collection means exporting a file. See what is Yaak.
3. Restfox: minimal and offline-first
An MIT client for the web or desktop that keeps everything local, with a layout Postman users recognise. No team features, no mocks.
4. Posting: offline in the terminal
A keyboard-driven terminal client with requests as YAML files, Apache 2.0. Works over SSH, which for some people is the only definition of offline that matters.
5. HTTPie CLI: scripts that need nothing
BSD-licensed, sessions stored on disk, runs anywhere a shell runs.
6. Insomnia with local projects
Insomnia (Apache 2.0) lets you store projects locally or in Git instead of Kong's cloud, and Enterprise can mandate local storage across an organization. Cloud features need an account; local projects do not need a connection.
7. Thunder Client inside VS Code
Works offline with collections in extension storage on the free tier. Git-tracked storage, which is what makes the collections portable, is paid from $3 per user.
8. Hoppscotch, self-hosted
Not offline on your laptop, but MIT-licensed and deployable from its repository inside your own network, which solves the air-gap case for a whole team rather than one person.
When "offline" really means "inside our network"
If the requirement is that tests, mocks, and imports run against services the public internet cannot reach, a single-user offline client solves it for one developer and leaves the team without shared mocks, docs, or scheduled tests. That is the case Apidog's deployment options are for:
- Desktop apps for macOS, Windows, and Linux, with mocks that run locally by default.
- A self-hosted runner, a Docker container inside your network that executes scheduled tests, scheduled imports, and mocks against private services, while the team collaborates on the spec in the cloud.
- An EU-hosted instance for data-residency requirements.
- An on-premises edition of the whole platform for organizations that cannot use SaaS at all, which is the full offline answer for a team.
Apidog itself is cloud-synced and needs an account, so it is not the tool for someone who wants no server involved at all; Bruno or Yaak are. It is the tool when a team behind a VPN needs one spec driving mocks, tests, and docs. The comparison with Postman on exactly this point is in Apidog vs Postman, and the team-level view is in the best Postman alternative for teams.
Choosing
- No account, no server, ever: Bruno (files) or Yaak (local database).
- Terminal only: Posting or HTTPie.
- A whole team inside one network: self-hosted Hoppscotch for a client, or Apidog on-premises for the full platform.
- Mostly online, some private services: Apidog with the self-hosted runner.
The wider comparison is in Postman alternatives in 2026, and the client-focused list is in the best API clients.
FAQ
Can Postman work offline? In a limited lightweight mode for local work; the workspace lives in Postman's cloud and needs an account.
What is the best offline Postman alternative? Bruno for most developers; Yaak if you want a local database rather than files.
Is there an offline Postman alternative for teams? Self-hosted Hoppscotch for a shared client, or Apidog's on-premises edition for the full platform inside your network.
Do offline clients import Postman collections? Bruno, Yaak, Insomnia, Thunder Client, and Apidog do.
