Comparison
Apidog designs the spec. Elva governs the API.
Design-first tools assume somebody keeps the spec honest. Elva derives it from code, grades every endpoint, gates breaking changes, and hosts the MCP gateway your agents call.

ApidogDESIGN-FIRST PLATFORM
An all-in-one workspace for designing, mocking, debugging, and documenting an API from a spec you author. Strong at the design loop, as long as someone keeps that spec in step with the code.Starts from a spec someone writesPer-seat pricing, plan-based limitsGovernance is review, not enforcement
ElvaAPI MANAGEMENT
A system of record that reads your repo, writes the specs, scores every endpoint, and enforces one contract per audience at runtime. Collections are an output, not the input.Starts from the code, rescanned every commitFlat pricing, unlimited members and endpointsGovernance blocks the publish
Four real differences
The gaps that matter once agents show up
01Derived from code, not authored by hand
A hand-written spec is a promise about the code. Nobody updates it on the busy week, and that is exactly when it starts lying.APIDOGThe spec is the input. Design-first is a good discipline, but keeping it aligned with the implementation is manual and permanent work.
ELVAElva reads routes, handlers, and types from the repo, writes the OpenAPI itself, and rescans on every commit. The spec cannot drift from the code.
02Scored for agent readiness, not just validity
A spec can be perfectly valid and still be useless to an agent: no descriptions, loose types, ambiguous auth.APIDOGValidation tells you the document parses and matches OpenAPI. Whether a consumer or an agent can act on it is left to review.
ELVAEvery endpoint is graded on design, developer experience, AI readiness, security, and performance, with a concrete fix attached and an AI that can apply it.
03Governance that can say no
Mocking a change is not the same as controlling it. Someone has to decide whether a partner gets to keep the old shape.APIDOGVersion history and diffs are there. Nothing stops a breaking change from reaching a consumer who depended on the old response.
ELVAContracts define what each audience sees per field. Breaking changes block the publish until approved, and the gateway enforces the same rules at runtime.
04The MCP server is the product, not an export
Agents do not read your docs. They call tools, retry badly, and act on whatever schema you hand them.APIDOGYou can produce a server from a spec. Hosting it, scoping keys per tool, redacting fields, and logging which agent did what is outside the picture.
ELVAHosted MCP servers with OAuth2, per-tool scopes, field redaction, rate limits, and a full log of which agent called which tool, in one place.

Switching
You do not have to throw anything away
Import your projects, keep the specs your team authored, and let Elva reconcile them against the code. The interesting part is what the code has that the spec does not.
01Import collections and specsApidog projects, OpenAPI files, environments, and Postman collections. Everything lands in the catalog with its history intact.
02Connect the repoThis is where the gap shows. Expect to find endpoints no collection ever mentioned, usually a third of your surface.
03Export back out any timeElva generates OpenAPI specs and Postman collections as deploy targets. No lock-in, and your designers keep the workflow they already like.
WHEN APIDOG IS ENOUGHYou are designing a new API from scratch, you want mocks before the backend exists, and the spec is the thing your team argues over. Apidog is a strong design loop and it will serve you well there.
WHEN YOU NEED ELVANobody can list every endpoint you own. A partner or an agent depends on your response shape. Someone asks which agent called what, and the honest answer is that you do not know. That is the day a client stops being enough.
FAQ
How is Elva different from Apidog?
Apidog is an all-in-one workspace for designing, mocking, and debugging an API from a spec you author. Elva derives the spec from code, grades every endpoint, gates breaking changes per audience, and hosts the MCP gateway your agents call.
Is Elva design-first or code-first?
Code-derived. The spec is generated from the repo and kept true on every commit; design intent lives in contracts layered on top, so the design and the implementation cannot silently diverge.
How does pricing differ from Apidog?
Apidog charges per seat. Elva plans are flat per workspace with unlimited members.
