“Postman alternative” has been one of the most-searched developer-tool queries for years, and the volume tells you something: a lot of people use Postman, and a meaningful share of them are actively looking for the exit. This post covers why — and where those teams actually land.
Why developers go looking
Across forums, reviews and our own conversations with users, the same four reasons keep coming up:
- Cloud-first collections. Since the offline Scratchpad was retired in 2023, sign-in and cloud sync are the expected path. For teams handling internal APIs, tokens and unreleased endpoints, that is a governance problem, not a convenience.
- Pricing. Per-user pricing across a whole engineering org is real money for what is, for many, “the app we test endpoints in” — and the deeper platform features push you up the tiers.
- Weight. Postman grew from a client into a platform, and the app carries all of it, whether you use it or not.
- Tool sprawl around it. Postman covers the API client; planning still lives in Jira, conversation in Slack, database work in another tool, docs in a fourth.
The alternatives, honestly
Insomnia is the closest like-for-like swap: a focused client with OpenAPI-first design workflows and, since 2023, per-project local, Git or cloud storage. It is owned by Kong and its core is open source. What it does not change is tool sprawl — it is a client, full stop.
Bruno is the privacy-maximalist option: MIT-licensed, offline, collections as plain-text files in Git. Perfect for solo developers with hard open-source requirements; more friction once a team wants shared environments, secrets handling and mocking without pull requests.
Hoppscotch is the zero-install option: open source, runs in the browser, self-hostable. Great for quick calls and locked-down orgs; a browser tab is inherently limited for mTLS, some auth flows and local services.
Apiboo Workspace — our product — is the consolidation option: a local-first desktop app that matches the serious client features (REST, GraphQL, WebSocket, SSE, gRPC; OAuth 2.0 PKCE, AWS SigV4, mTLS; scripts and a collection runner; local and cloud mocks; codegen for cURL and 8 languages) and then replaces the tools around Postman rather than just Postman itself: Kanban boards, team chat with an AI assistant, a MySQL/PostgreSQL/SQLite database manager, OpenAPI docs from collections, and rich-text docs with PDF export. Local by default, end-to-end encrypted personal vault, works offline, built in the EU, free to start.
What switching actually costs
Less than it used to. Collection import is a solved problem — Apiboo, Insomnia and Bruno all import Postman collections directly, and Apiboo also takes Insomnia, Bruno, OpenAPI, HAR and cURL. Environments and folder structures come across; the work is re-checking secrets (which should not have been in the export anyway) and re-wiring CI if you used Newman.
The practical playbook: export your Postman workspace, import it into one candidate, and run your normal week in it. Keep Postman installed. If you never open it, you have your answer.
When you should stay with Postman
If you rely on Postman’s governance and monitoring products, publish docs to its public API network, or have years of CI built on Newman and the Postman CLI, the migration cost may genuinely outweigh the wins. Alternatives make sense when what you need is the client and the everyday team workflow — that is exactly the ground where the newer tools are better.
