# Swagger Alternative — Routebase > Swagger UI and Swagger Editor are where most API teams start. They are also where most teams stop: nothing is hosted, nobody collaborates, and no test ever runs. Routebase takes the same OpenAPI file and runs your docs portal, mocks, tests, and monitoring from it. Canonical page: https://routebase.dev/swagger-alternative/ ## Why teams look past Swagger "Swagger" means two different things, and people arrive here from both. Some are running the open-source tools — Editor to write the YAML, UI to render it — and have hit the wall where a spec file in a repo stops being enough: no hosted portal, no review workflow, no way to prove the API still matches. Others are on SwaggerHub and have met a limit: 50 test executions a month, a portal that carries SmartBear's branding, or a feature that turns out to be a per-user add-on. Both problems have the same shape, and the row-by-row comparison further down is against SwaggerHub, since that is where the numbers are. - Everything that has to happen around a spec file: hosting, review, and proof that the API still matches - One spec drives the portal, the mocks, the tests, and the monitors - Every capability of a tier is included — no per-user add-on for the portal or the test runner - EU or US data residency chosen at signup, on every plan ## Where the open-source tools stop Swagger Editor validates a file. Swagger UI renders one. Neither hosts anything, neither has a second person in it, and neither runs a test — so the moment a team needs a portal on its own domain, a review before a breaking change ships, or proof that the deployed API still matches the document, the toolchain ends and the glue code starts. Routebase is that missing middle, and it reads the same OpenAPI file you already have. - A hosted, branded portal instead of a static UI bundle you deploy yourself - Spec branches and merge requests with breaking-change detection before publish - Live presence — see who is editing which endpoint, down to the field - Import your existing 3.0/3.1 spec unchanged; export it unchanged any time ## 50 test executions a month This is the number worth doing the arithmetic on. SwaggerHub's Individual and Team plans include 50 test executions per month, Enterprise 100 — and the pricing page defines the unit precisely: a suite counts each test individually. A modest suite of 30 tests, run once a day, is 900 executions a month. Against an allowance of 50, the second day of the month is where it stops. SmartBear sells a Test Pro add-on at EUR 27.92 per user/month; the pricing page does not state what allowance it carries. In Routebase, test runs are not metered. - No monthly cap on test executions, on any paid tier - 6 assertion types with 10 operators, 10 auth schemes — declarative, no scripting - Fixtures, seeds, and snapshots for reproducible data; OWASP API Top 10 scanning - Scheduled runs from Starter and CLI runs in CI, both uncapped ## A portal that carries your name, not your vendor's On SwaggerHub, the published portal comes with SmartBear branding on Individual, Team, and Enterprise alike; a custom domain and a portal without that branding are Enterprise Plus, which is a conversation with sales. The tiers also cap how many API products you can publish at 1, 2, and 5. In Routebase the branded portal with your own domain and automatic SSL is part of Pro at $19 per user, and there is no limit on how many APIs you document. - Your domain with auto-SSL on Pro — no vendor branding, no seat class - Unlimited projects and specs; publish as many APIs as you have - Try-it console on every endpoint, code examples in eight languages, full-text search - Versioned pages and llms.txt output for agents ## Design the contract visually, review it like code SwaggerHub puts a form editor beside the code editor. What it does not put below Enterprise is the linting that keeps a growing spec consistent — validation with custom rulesets starts there. Routebase treats both as table stakes: the whole contract in structured forms, and a style guide that runs on every change from the free plan up. - Three-panel editor: endpoint tree, structured forms, live preview - Visual JSON Schema builder with validation rules and generated examples - 53+ style guide rules with auto-fix suggestions, on every tier - 21 breaking-change rules checked across spec versions ## Mocks that rehearse the bad day SwaggerHub's automocking starts at the Team tier and serves what the spec documents. That is the happy path. The failures a frontend has to survive — a 500 at the wrong moment, a request that hangs, a rate limit — and the flows that only make sense with state need a mock that can do more than echo an example. - Realistic generated data: names, emails, addresses, not one placeholder repeated - Stateful mocks across a session, plus request variables like {{request.body.name}} - Fixed or random latency, 5xx responses, timeouts, connection resets, rate limiting - Proxy mode: mock the new endpoint, forward the rest to the real API ## One price instead of a stack of add-ons SwaggerHub's list price is the start of the bill. Portal Pro is EUR 27.50 per user/month, Test Pro EUR 27.92, Contract Testing Pro EUR 21.80, and Enterprise SSO EUR 5.58 — each per user, each on top. A Team seat that needs a decent portal and real test volume is EUR 32.34 plus EUR 55.42 in add-ons before anyone counts executions. Routebase Pro is $19 per user with the portal, the custom domain, the test engine, monitoring, and the MCP server inside it. - Every feature of a tier is included — nothing is a per-user add-on - Free plan to start; $9 Starter, $19 Pro, $39 Enterprise per user/mo (annual) - Enterprise is self-service from 25 seats — SSO, SCIM, and audit log export included - 14-day Pro trial on every account, no credit card ## Data residency as a signup choice SwaggerHub answers residency with deployment: SaaS, or on-premise if your requirements are strict — and on-premise is a sales conversation and an installation. Routebase answers it with a dropdown. Pick EU or US when you create the workspace, on any plan, and it stays there on Microsoft Azure, with the same features either way. - EU or US region on every plan, chosen at signup — no migration project - Same features in both regions - GDPR and DPA from a German vendor, without an enterprise negotiation ## Your spec is already the migration Whichever Swagger you are on, the artifact is a standard OpenAPI file — and that is the thing Routebase runs on. Import it and the portal, the mock server, and the linting exist immediately. What does not come across is the part the spec never held: the test suites. That work is mechanical rather than difficult, which is exactly what an agent over our MCP server is for. - OpenAPI 3.0 and 3.1 import, YAML or JSON — from a repo file or a SwaggerHub export - Portal, try-it console, and search generated from the spec on import - Style guide rules apply from the first import, with auto-fix suggestions on what they flag - An agent generates test suites from the endpoints, runs them, and fixes what fails - Everything the agent does runs under your roles and lands as a diff you review - Full OpenAPI export any time — the spec is yours, it always was ## The full comparison, row by row | Capability | Routebase | SwaggerHub | |------------|-----------|---------------| | Spec-first API design | Yes — Visual OpenAPI editor with spec branches and merge requests, 53+ style guide rules and 21 breaking-change checks before publish | Yes — Form editor and code editor; validation with custom linting (Spectral) from Enterprise | | Docs portal with custom domain | Yes — Branded portal generated from the spec: WYSIWYG editor, reusable snippets, page revisions, versioned pages, try-it and search; custom domain on Pro | Partial — 1 / 2 / 5 public products by tier, all with SmartBear branding; custom domain and branding removal on Enterprise Plus | | Hosted mock servers | Yes — Spec-driven mock servers with realistic generated data, stateful flows, latency and failure simulation, and proxy mode | Partial — Automocking from the Team tier; not on Individual | | API test execution | Yes — Declarative test engine — 6 assertion types, 10 operators, 10 auth schemes, multi-step scenarios with chaining, fixtures and snapshots; no scripting required | Partial — 50 test executions per month on Individual and Team, 100 on Enterprise — suites count each test individually | | Scheduled test runs | Yes — Included from Starter — independent of monitoring limits | Partial — Test automation is included, but every scheduled run draws from the same monthly execution allowance | | API monitoring | Yes — Uptime and contract checks generated from the spec, with alert policies, incidents and maintenance windows, from Pro | No — No uptime or endpoint monitoring listed on the pricing page or the tools documentation | | API security scanning | Yes — Active OWASP API Top 10 scanning against a running environment — 8 scanners, auth personas for access-control tests, findings with severity, remediation guidance and a security score | Partial — OWASP Top Ten standardization rules via Spectral against the definition; runtime security testing is a separate SmartBear product (ReadyAPI) | | MCP server for AI agents | Yes — Built-in MCP server: 400+ tools across 31 toolsets, 13 prompts, 12 resources; zero-install OAuth connector, RBAC-scoped on every plan | Yes — MCP server and callable AI tools documented; RBAC from the Enterprise tier | | Data residency choice | Yes — EU or US region chosen at signup, on every plan — German vendor, Azure-hosted | Partial — SaaS or on-premise for strict residency requirements — on-premise runs through sales, no region choice at signup | | Pricing model | Yes — Per user: free plan, then $9–$39/user/mo (annual) — every feature of a tier included | Partial — EUR 21.20 / 32.34 / 54.68 per user/mo (annual); Portal Pro, Test Pro, Contract Testing Pro and SSO are separate per-user add-ons | *Comparison as of August 2026, based on SwaggerHub's public pricing page and the Swagger tools documentation.

Routebase publishes a branded portal from your spec — try-it console, full-text search, code examples, versioned pages and your own domain with automatic SSL — instead of a bundle you host, style, secure and keep in step with the spec by hand. Everything Swagger UI renders, your consumers still get; the difference is that nobody on your team maintains the deployment. ### We use the free Swagger Editor. What do we gain? A second person, mainly. The Editor is a single-user window onto a file: no presence, no review, no history beyond your Git log. In Routebase the same spec is a shared object — live presence down to the field being edited, spec branches with merge requests, breaking-change detection before a merge, and a style guide that runs on every change. The file stays valid OpenAPI throughout, so nothing about this is a one-way door. ### How many test executions do I get? Test runs are not metered in Routebase — there is no monthly execution allowance on any paid tier, whether you run suites from the UI, on a schedule, or from CI. This is the sharpest difference in the table: SwaggerHub includes 50 test executions per month on Individual and Team and 100 on Enterprise, and its pricing page notes that suites count each test individually, so a 30-test suite run daily would exceed the Team allowance on the second day of the month. ### Does SwaggerHub not have an MCP server too? It documents one, so the question is what an agent reaches through it. Routebase exposes 400+ tools across 31 toolsets covering design, mocking, testing, documentation and monitoring — enough for an agent to build a specification and its test suites, not only read them — scoped by the same role-based permissions as your team, with RBAC on every plan rather than from a specific tier. ### Can I import a SwaggerHub API? Yes. Export it as OpenAPI 3.0 or 3.1 — YAML or JSON — and import that file. A dry run shows every warning and exactly what would be created before anything is written. Because the same operations exist as MCP tools, an agent can run the import and then build the test suites the spec does not carry, under your permissions, leaving you a diff. ### Does this replace Swagger Codegen? No, and it does not need to — the two sit at different points in the chain. Codegen turns a contract into server stubs and client SDKs; Routebase is where that contract is designed, governed, mocked, tested and published. A valid OpenAPI export from Routebase feeds your existing Codegen pipeline exactly as today's file does, so the generation step you already run keeps working unchanged. ### Where is my data hosted? You choose EU or US at signup and the workspace stays in that region, on every plan. Both run on Microsoft Azure. Routebase is a German company, so GDPR compliance and a DPA come without an enterprise negotiation or an on-premise installation. ### Am I locked in? No. Your specs export as standard OpenAPI 3.0/3.1 in YAML or JSON at any time — what you import is what you can take with you. That was true of your Swagger file too, and it is the property worth protecting. --- [Routebase](https://routebase.dev/) — [Sign up](https://app.routebase.dev/): Every account starts with a 14-day Pro trial — no credit card required.
