Why Design APIs Before Writing Code?
Discover AI-driven API development no-code platform with APITect. Start using our advanced platform today to boost your release cycle, improve productivity, and increase ROI.
One Contract. One Truth. Zero Miscommunication.
APITect becomes the single place where the API is defined, discussed, and approved. This keeps frontend, backend, and QA fully aligned on the same source.
Build Contracts Parallel With Confidence
Mocks and validations are generated automatically so teams can start instantly. Frontend and QA move ahead without waiting for backend dependencies.
Predictable, Repeatable, Reliable Delivery
Teams stop guessing because every contract is validated in real time. This prevents downstream chaos and keeps delivery consistent.
Minimal Handsoff & Rework. Maximum Velocity.
You eliminate the number one cause of sprint failures: API mismatches. This leads to smoother workflows and faster delivery.
Built for Teams Who Can't Afford API Chaos
Build a high-velocity engineering culture where every team is aligned, informed, and never blocked by unclear APIs again
Engineering Managers
APITect ensures predictable delivery by keeping every team aligned on one accurate API source of truth.
Tech Leads & Architects
APITect enforces standards, naming conventions, and architectural governance from day one to avoid rework.
Founders & CTOs
APITect reduces cost of delays and reworks, enabling your teams to ship faster by being on the same page.
Developer & QA Teams
APITect enables true parallel development with clear, agreed-upon API contracts with easy collaboration.
How It Works
Clear, fast, and AI-driven — from raw JSON to production-ready API contracts, mocks, and validations.
Sketch the Endpoint
URL. Method. Path Variables. Query Params.
Start by entering the endpoint details — HTTP method, route structure, path variables, and query parameters.
APITect's
AI Detection Engine automatically infers datatypes, required/optional flags, validation rules, and expected patterns for
every variable and parameter.
Paste Your JSON → Get Full Schema
AI transforms raw JSON into a fully customizable schema builder.
Paste a sample request or response body, and APITect immediately creates a structured schema with:
- Types (string, number, boolean, enum, array, object)
- Constraints and validations
- Auto-labeled fields
- Nested structures fully mapped
You can refine every detail through a no-code schema editor or accept AI suggestions for consistency.
Shape Behavior Without Code
Control how your API behaves. No code required.
Define your custom API requirements for:
- Custom request/response headers,
- Authentication rules,
- Validation requirements,
- Conditional logic.
Use APITect's to enforce standards, add restrictions, or create flow-specific behaviors.
Watch Validation Happen Live
Test instantly with our built-in Swagger-style validation.
Send sample requests and immediately see how your contract responds.
APITect performs real-time validation on
every field, parameter, header, and body — catching mismatches, datatype conflicts, missing fields, or undocumented changes.
Export Anywhere in 1 Click
One click. Every format your team needs.
Export clean, always-synced API definitions in:
- OpenAPI / Swagger
- TypeScript Interfaces
- Zod Schemas
- Any programming language code snippet
Share contracts and mocks across teams with a single link, or integrate them directly into frontend, backend, mobile, or CI pipelines.
Collaborate Without Friction
Keep every team aligned on the same source of truth.
Share contracts instantly with your entire team — frontend, backend, QA, and product.
APITect ensures everyone works from the same accurate, up-to-date API definition. No more miscommunication, no more outdated docs, no more integration surprises.
Start by entering the endpoint details — HTTP method, route structure, path variables, and query parameters.
