Postman vs Insomnia
Of all the alternatives, Insomnia is the one that feels most like Postman — same mental model, same workflow, roughly two-thirds the price. It also carries its own history of a plan change that annoyed people. Both facts belong in the decision.
Pick Insomnia if you want the least disruptive swap: a full-featured GUI client with a real free tier (Git Sync for up to 3 collaborators), Pro at $12/user/month against Postman's $19, and Apache-2.0 source. Know the history: Insomnia 8.0 forced a cloud account in 2023 and Kong walked it back in 8.3. Current builds work locally without one.

Where Insomnia wins
A free tier that still allows a small team
This is the direct answer to what changed in March 2026. Postman's Free plan is now one user; a second person needs a $19/month seat. Insomnia's Free plan includes Git Sync for up to three collaborators, so a two- or three-person team keeps sharing collections at no cost. Above that you pay $12/user/month rather than $19 — a five-person team is $720/year on Insomnia Pro against $1,140 on Postman Team.
You choose where data lives
Insomnia supports three storage modes per project: local only, Git Sync into your own repository, or Insomnia Cloud. Postman's model is the vendor workspace. If your objection to Postman is less about price and more about your API surface sitting in someone else's cloud, this is the lever.
Familiarity, which is an underrated cost
Insomnia's request/folder/environment model maps closely onto Postman's, the import is the cleanest of the mainstream options, and the UI takes about an afternoon to get used to. Bruno and Hoppscotch ask you to change how you think about collections; Insomnia mostly doesn't.
Where Postman still wins
Scheduled monitors that run collections from hosted infrastructure have no direct Insomnia equivalent. The API Catalog, published documentation, the workspace/governance layer for a large org, and the sheer size of the ecosystem and integration list all remain Postman's. And at Enterprise level the two converge in capability — Postman $49 vs Insomnia $45 — so the price argument thins out at the top end.
The honest caveat about Insomnia
In 2023, under Kong, Insomnia 8.0 required a cloud account to use the app and defaulted new projects to cloud storage. It was badly received and it is the single biggest reason Bruno and Hoppscotch grew when they did. Kong reversed course: 8.3 restored a fully local Scratch Pad and local-only vault use without an account, and that is where things stand today. Take it as evidence in both directions — the vendor did back down under pressure, but it also tried it in the first place.
Migrating Postman → Insomnia
Import Postman collection v2/v2.1 exports plus environments directly; this is the least lossy migration of the group. Budget rework for pre-request and test scripts written against Postman-specific APIs, and replace anything running on monitors separately (a scheduled CI job with Inso CLI covers most cases). Export from Postman before you downgrade — the Free plan's recovery window for a deleted collection is one day.
Common questions
Postman vs Insomnia — FAQ
Is Insomnia free for a team?
Partly. The Free plan includes Git Sync for up to three collaborators — more team collaboration than Postman's Free plan offers after March 2026, when it became single-user. Beyond three people you move to Pro at $12/user/month, or Enterprise at $45/user/month for SSO, RBAC and self-hosted storage. So Insomnia undercuts Postman at every comparable tier, but it isn't free at team scale the way Bruno or a self-hosted Hoppscotch is.
What happened with Insomnia 8.0 and the forced account?
Insomnia 8.0, released in 2023 under Kong, required a cloud account to use the app and defaulted new projects to cloud storage. The reaction was severe and drove a wave of users to Bruno and Hoppscotch. Kong reversed it: 8.3 restored a fully local Scratch Pad and local-only vault usage without an account. The reversal is real and current builds don't force an account — but the episode is worth knowing when you weigh how likely the terms are to move again.
Can Insomnia import Postman collections?
Yes — collection v2/v2.1 exports plus environments, and it's the smoothest migration of the mainstream options because the two apps model requests, folders and environments similarly. Complex Postman-specific pre-request and test scripts still need rework, and there's no drop-in replacement for monitors or hosted mock servers.
