📋 How this list is curated

Open-source products are ordered by GitHub star count — an objective, CI-checked popularity signal, not a quality ranking or an endorsement. Products with fewer than 100 stars sit in a collapsed Emerging projects section and graduate into the main list once they cross that threshold.
Bold marks resources with reproducible code publicly available.
Descriptions are factual, not promotional (see the contributing guide).
This list is maintained by Bloo-Mind AI and the Ubiquitous AGI team at TeleAI. Entries affiliated with the maintainers are marked with † and follow the same ranking, format, and style rules as every other entry. One convention applies to all entries regardless of affiliation: an API-compatible drop-in replacement for a listed product is nested under that product as an unranked sub-item rather than given its own star-ranked position.
Projects that are inactive, archived, or whose claims are disputed move to the Archival subsection with a neutral status label, links to the evidence, and the date the status was last checked.

Agent Memory Leaderboard [code] Public evaluation platform: participants expose Add/Search APIs and are scored on textual-memory and coding-agent-memory tracks.
Agent Memory Benchmark (AMB) [code] Open harness and leaderboard scoring memory providers on accuracy, latency, and token cost over six datasets; built by Vectorize, whose Hindsight is among the providers.
OmniMemEval [code]
Are We Ready For An Agent-Native Memory System? (The MemoryData Paper) [code]

🔒 Memory Security & Defense

Agent Memory Guard [code] OWASP runtime defense layer that screens agent memory writes for poisoning: multi-layer validation with semantic anomaly detection, entropy scoring, and provenance verification.
From Untrusted Input to Trusted Memory: A Systematic Study of Memory Poisoning Attacks in LLM Agents (The MPBench Paper)
inspeximus (formerly mnemo) poisoning probes [attack] [defense] Runnable probe scripts demonstrating that provenance written into a memory record is forgeable, and that a retrieval-time corroboration gate raises the cost of memory-poisoning attacks.
Mnemosyne (by rsh1k) [code] Gateway guarding agent memory reads and writes: provenance-based trust tiers keep non-trusted content off instruction surfaces; injection and obfuscation detectors, HMAC-signed records, hash-chained audit log.
Securing LLM-Agent Long-Term Memory Against Poisoning: Non-Malleable, Origin-Bound Authority with Machine-Checked Guarantees (TMA-NM) [code] [data]
MAQS — Memory Architecture Quality Standard [spec] Audit checklist for long-term memory in LLM agents: 96 items with CRIT/IMP/REC criticality covering data loss, poisoning, leakage and growth, incident-derived per the author; EN/RU.
MAQS-Way [spec] [eval] Specification connecting memory policies to implementation and verification: machine-readable canon, schemas, conformance vectors, pinned stub-model behavioral isolation test on Mem0 (self-reported).
Memory Poisoning Lab [code] [demo] Local test range replaying six synthetic memory-poisoning attacks against a scripted agent on three memory backends, with write screening, origin-aware recall and conflict-scoped repair.
