BrrainyMemory for Your Whole Week vs. Memory for Your Coding Agents
Brrainy vs. Beacon (Asymptote Labs)
Beacon is an MIT-licensed, local-first memory layer for AI coding agents: it learns workflows, corrections and repo conventions across Claude Code, Cursor, Codex, OpenCode and other harnesses, and shares them over MCP or Agent Skills. That is a real answer to re-explaining yourself inside a terminal, and it is free. Brrainy does the same job for agents and goes wider - your assistants, apps, mail and calendar - then briefs you each morning. Checked against Beacon's public README and releases on 23 October 2026; Brrainy publishes this page.
Side-by-Side Architectural Matrix
Objective comparison based on verifiable technical capabilities and public rate cards.
| Capability | Beacon (Asymptote Labs) | Brrainy |
|---|---|---|
| Scope of capture | Coding harnesses: Claude Code, Cursor, Codex, OpenCode and 20+ others, plus a local browser-extension collector added October 2026. | Your assistants (ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek), 25 app connectors, and the web, desktop, mobile, browser and IDE surfaces. |
| Where the memory lives | Local-first JSONL on your own machine; sharing sessions goes through Beacon Cloud. | Hosted and space-scoped, with row-level isolation between personal and organisation work. |
| Agent access | Retrievable via MCP or Agent Skills from the harness you are in. | Hosted MCP server with two tools, brain_recall and brain_remember, for any MCP-capable client. |
| Proactive delivery | On demand: retrieval plus exact session replay. No scheduled brief in the public README. | A scheduled brief by email, in-app inbox or push: open loops, commitments, and what still needs a decision. |
| Knowledge model | Session history plus learned workflows, corrections and repo conventions. | A bi-temporal knowledge graph of entities and facts that tracks contradictions over time. |
| Cost and licence | Free and open source (MIT); an enterprise-edition install path appeared in October 2026, pricing not published. | Subscription plans with BYOK on model compute; current plans are on the pricing page. |
When Beacon is the right choice
Your agent work is the work that matters, you want the memory on your own disk under an MIT licence, and you would rather not have a hosted account in the loop.
When Brrainy is the right choice
The context worth keeping is not only in your editor: it is in chats, mail, calendar and docs, and you want it remembered, connectable over MCP, and briefed back to you without asking.
