Hoppscotch vs API Dash
Both are alternatives to Postman. Here's how they stack up — verified facts, no spin.
Also searched as API Dash vs Hoppscotch — same comparison, one verdict.
Hoppscotch and API Dash are closely matched on ownership (90 vs 89) — this one comes down to pricing and to which trade-offs below you can live with.
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.
API Dash
A fully offline, cross-platform FOSS API client, mobile included.
API Dash is a fully open-source, cross-platform API client built with Flutter that runs completely offline with no account, on desktop and mobile alike. It handles everyday REST and GraphQL workflows, imports collections, and can generate client code. It is the most sovereign option on this list in posture, though it is younger and less battle-tested than the others.
Side by side
10 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 2 GB for the self-hosted stack | Whatever your machine already has: it is an ordinary desktop app. The heavy part is building a current version from source, which needs the Flutter SDK and the platform toolchain (on Windows, full Visual Studio with the C++ desktop workload). |

| Setup timeHonest first-install estimate, not the marketing quickstart. | 1 hour for the self-hosted edition | 5 minutes for the packaged build. An hour or more to build the current version from source. |
| Ongoing maintenanceThe part nobody budgets for. | Low. The self-hosted stack is a normal web app and upgrades cleanly. | Nothing on the server side. Because the packaged desktop builds have been frozen since November 2023, getting new features means pulling and rebuilding from source. |
Hoppscotch edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.

- −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
API Dash
Strengths
- +Fully open-source (Apache-2.0)
- +Completely offline and local with no account
- +Cross-platform including mobile (Flutter)
- +Actively developed FOSS project
Trade-offs
- −Younger and smaller community than the others
- −Fewer advanced and enterprise features
- −Smaller plugin and integration ecosystem
- −Less battle-tested for large team workflows
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 API Dash
if fully open-source (Apache-2.0).
Neither, yet
if both carry a real cost you should weigh first — default experience is the hosted cloud at hoppscotch.io, and younger and smaller community than the others. 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.
Self-hosting Hoppscotch
2 GB for the self-hosted stack RAM · 1 hour for the self-hosted edition
$12–20/mo self-hosted, or free in the browser
Self-hosting API Dash
Whatever your machine already has: it is an ordinary desktop app. The heavy part is building a current version from source, which needs the Flutter SDK and the platform toolchain (on Windows, full Visual Studio with the C++ desktop workload). RAM · 5 minutes for the packaged build. An hour or more to build the current version from source.
$0 — it runs on the machine you already own
Hoppscotch vs API Dash — common questions
Is Hoppscotch a better fit than API Dash for api development?
It depends on what you are optimising for, and the honest split is this: Hoppscotch scores 90 to API Dash's 89 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. API Dash earns its place on a different axis — fully open-source (Apache-2.0). 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. API Dash 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 API Dash?
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 API Dash 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.
