No description of LSD yet.

MockBase is a hosted API mocking tool: click once and get a live HTTPS endpoint you can point a frontend, mobile app, or CI pipeline at, before the real backend exists. Each mock supports multiple routes, each with its own status code, response body, and optional delay, and can go well beyond...

Questions & Answers

As answered by people managing LSD and MockBase.

Who are some of the biggest customers of your product?

MockBase's answer:

MockBase is currently in public beta — there isn't a public customer list yet.

What makes your product unique?

MockBase's answer:

Most mock API tools make you pick one thing: a local desktop app (Mockoon), a zero-setup hosted stub (Beeceptor), or a spec-driven mock tied to a collection (Postman). MockBase puts conditional matching, sandboxed Jinja2 templating, stateful CRUD (a mock that actually remembers what you POSTed to it), chaos injection, and OpenAPI import/export into one hosted endpoint, with a live WebSocket request inspector on every mock. It's usable with zero signup — one click gets you a working endpoint with sample routes already on it.

Why should a person choose your product over its competitors?

MockBase's answer:

If you need more than "return this JSON" — a mock that behaves differently based on a header, remembers what you created and lets you read it back, or fails on purpose at a rate you control to test retry logic — that combination usually means stitching together a local tool plus custom code. MockBase bundles it into one hosted URL your whole team (or a CI pipeline) can hit, without anyone running a local server.

How would you describe the primary audience of your product?

MockBase's answer:

Frontend and mobile developers who need to build against an API before the backend is ready, QA/test engineers who need to reproduce specific error conditions (timeouts, rate limits, partial failures) that are hard to trigger against a real dependency on demand, and teams doing API-first development who want to agree on a contract and start building in parallel instead of waiting.

What's the story behind your product?

MockBase's answer:

Frontend work rarely waits for backend work to finish, and standing up a throwaway server just to unblock yourself is its own chore — dependencies, a port to remember, a process to keep alive. MockBase exists for that specific moment: a live endpoint in seconds, no server to babysit. It's deliberately narrow — not a full API platform with design, docs, and team management bundled in, just mocking, done well enough (dynamic responses, statefulness, realistic failure injection) to actually build and test against.

Which are the primary technologies used for building your product?

MockBase's answer:

Python (FastAPI) on the backend with Redis for the hot-path mock configuration, request logs, and state storage, and PostgreSQL for accounts and content. The frontend is React with Vite and Tailwind CSS. Dynamic response templating runs on a sandboxed Jinja2 environment.
