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

Apidog
DESIGN-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 writes
Per-seat pricing, plan-based limits
Governance is review, not enforcement
Evlio
API 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 commit
Flat pricing, unlimited members and endpoints
Governance blocks the publish
Four real differences
The gaps that matter once agents show up
01
Derived 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.
APIDOG
The spec is the input. Design-first is a good discipline, but keeping it aligned with the implementation is manual and permanent work.
EVLIO
Evlio reads routes, handlers, and types from the repo, writes the OpenAPI itself, and rescans on every commit. The spec cannot drift from the code.
02
Scored 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.
APIDOG
Validation tells you the document parses and matches OpenAPI. Whether a consumer or an agent can act on it is left to review.
EVLIO
Every endpoint is graded on design, developer experience, AI readiness, security, and performance, with a concrete fix attached and an AI that can apply it.
03
Governance 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.
APIDOG
Version history and diffs are there. Nothing stops a breaking change from reaching a consumer who depended on the old response.
EVLIO
Contracts define what each audience sees per field. Breaking changes block the publish until approved, and the gateway enforces the same rules at runtime.
04
The 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.
APIDOG
You 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.
EVLIO
Hosted MCP servers with OAuth2, per-tool scopes, field redaction, rate limits, and a full log of which agent called which tool, in one place.

You do not have to throw anything away
Import your projects, keep the specs your team authored, and let Evlio reconcile them against the code. The interesting part is what the code has that the spec does not.
01
Import collections and specs
Apidog projects, OpenAPI files, environments, and Postman collections. Everything lands in the catalog with its history intact.
02
Connect the repo
This is where the gap shows. Expect to find endpoints no collection ever mentioned, usually a third of your surface.
03
Export back out any time
Evlio generates OpenAPI specs and Postman collections as deploy targets. No lock-in, and your designers keep the workflow they already like.
WHEN APIDOG IS ENOUGH
You 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 EVLIO
Nobody 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 Evlio different from Apidog?
Apidog is an all-in-one workspace for designing, mocking, and debugging an API from a spec you author. Evlio derives the spec from code, grades every endpoint, gates breaking changes per audience, and hosts the MCP gateway your agents call.
Is Evlio 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. Evlio plans are flat per workspace with unlimited members.
