Hoppscotch vs Insomnia
Both are alternatives to Postman. Here's how they stack up — verified facts, no spin.
Also searched as Insomnia vs Hoppscotch — same comparison, one verdict.
Both are api development tools with the same broad shape, but Hoppscotch scores 90 against Insomnia's 82 on data ownership and exit cost — the gap is in how easily you could leave.
Hoppscotch
An open-source, browser-based API ecosystem you can self-host.
Hoppscotch is an open-source API development tool that runs in the browser as an installable PWA with offline support, covering REST, GraphQL, WebSocket, and Server-Sent Events. It is quick to start with nothing to install, and teams that want a shared workspace can self-host the full stack on their own infrastructure. The default hosted experience at hoppscotch.io is cloud-based, with a paid cloud team tier for managed collaboration.
Insomnia
A mature, multi-protocol API client with a fully local storage mode.
Insomnia is an open-source, cross-platform API client maintained by Kong, covering REST, GraphQL, gRPC, WebSocket, and SSE. Its Local Vault and Scratch Pad options keep collections 100% on your device, and Git Sync stores them in a repository you control, while optional Cloud Sync adds end-to-end-encrypted team collaboration. It is well-established and feature-rich, though most capabilities beyond the local Scratch Pad require a (free) account.

| Pricing | Free and open-source; free hosted cloud; optional paid cloud team tier; self-host for free | Free with a generous plan; paid tiers for unlimited collaboration, Git Sync, and org/SSO features |
| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 2 GB for the self-hosted stack | 700 MB as an Electron app |
| Realistic running costWhat the box costs each month if you run it yourself. | $12–20/mo self-hosted, or free in the browser | $0 — it runs on the machine you already own |
| Setup timeHonest first-install estimate, not the marketing quickstart. | 1 hour for the self-hosted edition | 10 minutes |
| Ongoing maintenanceThe part nobody budgets for. | Low. The self-hosted stack is a normal web app and upgrades cleanly. | None beyond updates, but check each release for account requirements. |

Hoppscotch
Strengths
- +Open-source (MIT)
- +Runs in the browser with an installable, offline-capable PWA
- +Supports REST, GraphQL, WebSocket, and SSE
- +Can be self-hosted for a shared team workspace
Trade-offs
- −Default experience is the hosted cloud at hoppscotch.io
- −Self-hosting requires running and maintaining Docker services
- −A paid cloud team tier exists for managed collaboration
- −Browser-based model differs from a native desktop app
Insomnia
Strengths
- +Open-source (Apache-2.0), backed by Kong
- +Local Vault and Scratch Pad allow fully local storage
- +Git Sync keeps collections in your own repository
- +Mature and multi-protocol (REST, GraphQL, gRPC, WebSocket)
Trade-offs
- −Most features beyond the local Scratch Pad require a free account
- −The product is steered toward Kong's cloud
- −Premium collaboration and Git Sync sit on paid plans
- −Some users prefer a fully no-account tool
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Hoppscotch
if a lower exit cost matters more to you than any single feature, and open-source (MIT).
Choose Insomnia
if open-source (Apache-2.0), backed by Kong.
Neither, yet
if both carry a real cost you should weigh first — default experience is the hosted cloud at hoppscotch.io, and most features beyond the local Scratch Pad require a free account. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
Hoppscotch vs Insomnia — common questions
Is Hoppscotch a better fit than Insomnia for api development?
It depends on what you are optimising for, and the honest split is this: Hoppscotch scores 90 to Insomnia's 82 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Insomnia earns its place on a different axis — open-source (Apache-2.0), backed by Kong. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Hoppscotch keeps its data local or in open formats, so leaving is an export rather than a negotiation. Insomnia is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Hoppscotch or Insomnia?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Hoppscotch and Insomnia both alternatives to Postman?
Yes — both appear in our Postman comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Postman and now choosing between the two replacements, which is a narrower and much easier question.
