MemPalace (~53.6K stars) claims best-benchmarked, against mem0 (~57.8K) and claude-mem (~80.8K) (GitHub). Agent memory went from experimental nicety to a competitive subcategory with published benchmarks. Pair this with the local-first angle: Mnemo offers a Rust + SQLite + petgraph memory layer with no cloud dependency (GitHub). Portable, controllable memory is having a moment.

MemPalace (57,821 stars, v3.6.0) reports 96.6% raw recall@5 on LongMemEval with no LLM required, 98.4% with hybrid v4 on a held-out 450 questions, LoCoMo R@10 rising 60.3% → 88.9%, ConvoMem 92.9%, MemBench 80.3%, while explicitly refusing head-to-head comparison against Mem0,...
I check Product Hunt maybe once a week and usually regret it. Today's board is worth reading as market structure. The July 30 leaderboard: SKI at 277 upvotes (free voice input for Claude Code and Codex). AI Search Console at 249 (prompt analytics and citation mapping). Memmy A...
Rust, created May 14, at 2,643 stars (GitHub). Every run produces checkpoints linking a commit to the session that made it, including prompts, tool calls and reasoning. It runs Claude Code, Codex, its own agent and anything from the ACP registry side by side against one codeba...
The submission titled "CEO fired developers to make room for AI. Developers create open source AI CEO" pointed at SenteLabsAI/OpenExecutive, an Apache-2.0 FastAPI and Next.js 15 app running eight specialist Claude agents (CSO, CFO, CHRO, General Counsel, COO, CMO, CPO, Board C...
Triple-stream retrieval (BM25 keyword, vector embeddings, knowledge-graph traversal) fused via Reciprocal Rank Fusion on the iii engine, with SQLite for state and an in-memory vector index, no external database. The economic claim: ~170K tokens/year (~$10) versus ~650K tokens...
claude-mem (89.3K stars) targets seven harnesses. lean-ctx (3.5K stars, Rust, 76 MCP tools) uses 60-90% token reduction as its headline metric. Wienerdog surfaced on HN August 2 offering memory plus self-improving skills for both Claude Code and Codex. All three are harness-ne...
