Open-source (Apache 2.0), self-hostable agent memory framework launched June 2026 — multimodal ingestion, self-evolving memory, agent trajectory learning, and transparent Memory Bank management.
Summary
Open-source (Apache 2.0), self-hostable agent memory framework launched June 2026 — multimodal ingestion, self-evolving memory, agent trajectory learning, and transparent Memory Bank management.
Second-generation entry in the open memory-framework field: where Mem0 extracts facts and Zep builds temporal graphs, EverOS's angle is learning from agent *trajectories* (what the agent did) and restructuring memory as it accumulates.
- "Best overall framework 2026" is the vendor's own positioning — independent benchmarks (LoCoMo, LongMemEval placements) were not yet published at launch.
- Self-evolving memory is a double-edged sword: memory that rewrites itself needs the transparent Memory Bank auditing the framework ships, or drift goes unnoticed.

Definition
An open-source **agent memory framework** from Evermind, released June 2026 under Apache 2.0. Differentiators over the extraction-pipeline generation of memory frameworks: **multimodal ingestion** (not just chat text), **self-evolving memory** that restructures itself as the agent learns, **agent trajectory learning** (the framework learns from what the agent *did*, not just what was said), and a transparent, inspectable **Memory Bank** management layer. Fully self-hostable. Positioned by the vendor as the best overall open-source agent memory framework of 2026. Per [Evermind — Best Open Source Agent Memory Frameworks 2026](https://evermind.ai/blogs/best-open-source-agent-memory-frameworks-2026).
First-generation memory frameworks extract atomic facts and retrieve them by similarity — which preserves *what was said* but loses *what the agent learned by acting*. EverOS's trajectory-learning angle targets that gap: memory that improves the agent's future behavior, not just its recall. The self-evolving design responds to a known failure mode of static memory banks — they accrete stale facts that degrade retrieval precision over time.
Self-hosted agent memory for teams that can't ship interaction data to a managed service, multimodal agent memory (documents, images, structured data), agents that should learn from their own action history, transparent memory auditing where the operator needs to inspect and edit what the agent remembers.
Recent developments
Source note: sourced almost entirely from the vendor's launch material — independent coverage queued; treat capability claims (and the vendor's own 'best framework' ranking) accordingly.
- Launch (June 12, 2026) — Apache 2.0, self-hostable. Multimodal ingestion + self-evolving memory + agent trajectory learning as the headline capabilities; enters a field where Mem0 leads on ecosystem breadth and Zep on temporal reasoning. Per Evermind — Best Open Source Agent Memory Frameworks 2026.
