What we checked

A missing tick means we have not measured it. A red mark is a check that failed.

App accessible
The project site answered. That is not the installed tool running.

Development

One snapshot so far

Commits landed in the last 90 days.

We hold one capture of this repository, so there is no trend to show yet. That is a fact about how long we have been watching, not about the project.

Evidence

Each bar is one request to the project's own site

This one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.

We hash the visible text on every check, so a redesign registers and a rotating advert does not. An app that has not changed in a long time is not necessarily abandoned — but it is a fact worth knowing before you depend on it.

What it does

BrainLayer gives any MCP agent persistent memory that survives restarts, compactions, and context limits. It stores decisions, learnings, and corrections in one SQLite file and searches knowledge with hybrid vector and keyword retrieval. Install with pip; it is free, open source, and local-first.

What people say

No reviews yet.

We would rather show none than invent them.

Embed this status

Put it in your README. It updates itself every time we check, and links to your verification record — evidence a stranger can read, not a page selling them something.
