Llmock
piyook · App
LLMock is a local server that imitates LLM APIs, so you can build and test AI-powered applications without API costs or an internet connection. Presets cover OpenAI-style chat completions, the Anthropic Messages API, the Gemini format and embeddings. Rules return canned text or JSON for requests containing a string you choose, and a chaos mode fails calls with errors such as 429 or 500, including failures partway through a stream. A live dashboard shows each request.
Written by ooruby from the README of llmock 3.12.0.

Why it's useful
Your tests can run against predictable, repeatable replies and deliberate failures instead of a live model.
What you could do with it
- Point your app at the mock chat endpoint and get predictable replies while you build the interface.
- Make one chosen prompt fail with a 429 or a dropped stream to check how your retry logic copes.
- Return canned JSON for any request that contains a chosen phrase, then review it in the live dashboard.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Command execution is bounded
- inventory
- node child_process (scripts/llmock.mjs:1)
- synchronous shell execution (scripts/llmock.mjs:7)
- node child_process (scripts/postinstall.mjs:2)
- synchronous shell execution (scripts/postinstall.mjs:8)
- An inventory of where the code starts another program, not a verdict on this row: whether each one runs a fixed program or whatever it is handed takes a reading by hand.
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 3.12.0, the file with digest sha512-GD/0RQOe0CQGnY5DEe2JVSEzjak4azWiyM3flFdHS0pAPVA9DZUCbQk7ST3hKmo6muEvSdrELbIL1PPdb8wkUA==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y llmock@3.12.0Pinned to 3.12.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
