Workflow consolidator · 2026

Design, test, and publish AI-ready APIs in three tools.
One.

Visual flow builder, server-side execution, team workspaces, and a six-tool MCP server — in a single sub-2-second editor. Drop the Postman seat tax. Answer the AI-readiness mandate. Ship the spec.

$29/mo: flat — never per-seat
< 2s: first-paint at the edge
∞: members on paid plans

The math, plainly

A 5-person team pays $95/mo for Postman seats.
OpenAPI Studio Team is $29.

Not a "competitive" price. A ~70% reduction, anchored to what your team already pays per-seat — and with unlimited members. Same workflow, 30-day execution history, server-side execution, and the six-tool MCP server included — no portal subscription on top.

The old way

Per month

Postman Team · 5 seats × $19 $95

Per-viewer / observer seat tax extra

Mock servers (limited) extra

Docs portal · separate vendor +$79

OpenAPI Studio Team

Flat rate

Unlimited workspaces · members incl.

30-day execution history incl.

5,000 MCP requests / day incl.

Private hotlinks · access tokens incl.

Six-tool MCP server · AI-ready incl.

Source: Postman Team list price ($19/seat/mo, March 2026) × 5 seats. Team here is flat $29/mo regardless of headcount, with unlimited members — see /pricing for full limits. Annual billing is roughly two months free.

The promise · plainly

Three vertices. One tool that hits all three.

Most teams stitch three categories together: a spec editor, an API client, and an AI publishing layer. Each vendor optimises for the one they were born in. We refuse the trade-off.

01 / Design

Visual flow builder

Your API as a directed graph, not a YAML wall. Click an endpoint to edit; drag to restructure paths. Form-driven editors for every OpenAPI 3.x field — no syntax to memorise.

vs Swagger Editor: a text editor with autocomplete.

02 / Test

Server-side execution

Hit endpoints from inside the editor. The proxy worker handles CORS, captures full request/response, and keeps a 7-day execution history per endpoint. Pin responses worth keeping.

vs Postman: $12/seat for the same call.

03 / Publish

One-click MCP server

Every spec becomes six tools any AI agent can use: search · get · create · update · run · analyze. Auto-listed on the AI Coach registry. Claude Desktop and Cursor consume them natively.

vs everyone else: doesn't exist.

Only OpenAPI Studio holds all three vertices.

Apidog gets close — but charges per-seat and ships an MCP client, not a server. The rest pick a corner and stay there.

Postman Test ✓ · Design ◐ · MCP client only
Stoplight Design ✓ · Mock only · No MCP
Apidog All three — but per-seat, no MCP server
Scalar Refs ✓ · Client ✓ · MCP gen, manual

For the AI-readiness mandate

Your APIs, accessible to Claude. Cursor. Kilo.

The 2026 mandate from your VP isn't a pitch deck — it's a deadline. Publish your spec, get an MCP server in return. Six tools, fully RBAC-aware, ready to wire into any agent that speaks MCP.

claude desktop · mcp · payments-api

# In Claude Desktop, after connecting your spec…
user> Find every endpoint that accepts a Stripe customer id

claude> search(query="customer_id parameter")
        → 4 endpoints matched
          GET /v1/customers/{id}
          POST /v1/charges
          GET /v1/subscriptions
          DELETE /v1/payment_methods/{id}

user> Run the GET on the staging server with id=cus_test_42

claude> run(method="GET",
        path="/v1/customers/{id}",
        server="staging",
        params={ id: "cus_test_42" })

# Editor scope: viewer can run; editor can update; owner can delete.

Six tools, one auth handshake

Match endpoints by path, tag, method, or description.

get

Fetch endpoint detail with schemas and examples resolved.

create

Add a new endpoint to the spec. Editor role required.

update

Patch operation, params, schemas, or security blocks.

run

Execute via server-side proxy. Full response captured.

analyze

Validate the spec, surface drift, suggest fixes.

Without the sleight of hand

Three things competitors charge for, included.

F·01

Cloud persistence, not localStorage

Every keystroke is saved to D1 at the edge. Sign in from any device, any browser. The "I lost my spec" support ticket disappears.

localStorage clears on cache wipe
→ D1 persistence + version history

F·02

Workspaces with real RBAC

Owner / Editor / Viewer. Invite by hashed email link. Viewers can execute APIs but can't modify the spec — perfect for QA, PMs, and clients.

$12/seat just to add a viewer
→ Unlimited members on Team · $29 flat

F·03

Hotlinks & access tokens

Public spec at /v1/specs/your-slug.json, KV-cached at the edge. Private specs gated by access tokens. CORS handled. ETags handled.

$79/mo for a docs portal
→ Stable URL · <100ms response

Two readers · two reasons

Built for the developer and the manager who signs the bill.

For developers

Flow & Power

Time to first finished call is the metric you actually care about. We measure it in seconds.

Visual flow builder · click to edit, drag to restructure
Server-side execution · CORS handled, no Electron app
Import & convert · Swagger 2.0 → 3.0 in one step
Sub-2-second first paint · Cloudflare edge
Six-tool MCP server · publish any spec to AI agents

For managers

ROI & Governance

Justify the tool in a 2-minute conversation with your VP. Show the displaced cost, the AI-readiness story, and the audit trail.

$29/mo flat · cost-line you can defend in any review
AI-readiness reporting · per-spec, MCP-published checklist
Hotlink analytics · who consumes your specs, how often
Workspace RBAC · viewers can run but not modify
Credential vault · secrets stay out of the spec

Pricing · transparent
