Agentmemory

Agentmemory

Persistent memory for Claude Code, Codex & coding agents

Agentmemory Preview

Unlock unprecedented capabilities for your AI agents by providing Hermes, Claude Code, and Codex with truly infinite memory. Agentmemory is rapidly gaining recognition, highlighted by its trending status on GitHub with over 5,000 stars, demonstrating its impact within the developer community. This innovative solution dramatically optimizes token usage; for instance, while a CLAUDE md dump might consume 22,000 tokens for 240 observations, Agentmemory achieves the same with only 1,900 tokens, representing a remarkable 92% reduction. Furthermore, as built-in memories become inefficient and invisible after just 1,000 observations, Agentmemory ensures 100% searchable and accessible memory retention. Benchmarked across 240 real coding sessions, it consistently delivers up to 95% fewer tokens per session, enables 200 times more tool calls before encountering context limits, and is proudly 100% open source, offering transparency and flexibility for advanced AI development.

Minions

Minions

Open source mission control for Hermes agent

Minions Preview

While your Hermes Agent excels at single tasks, managing multiple agents in parallel can quickly descend into chaos, leading to silently failing cron jobs, blocked tasks, and excessive time spent on troubleshooting rather than achieving results. Minions provides a powerful, unified task board to oversee all your agent operations with clarity and control. Each running task benefits from periodic check-ins, automatic retries when stuck, and intelligent escalation only after genuinely exhausting all alternatives. Currently compatible with Hermes Agent, Minions is continuously expanding its support to include more runtimes, ensuring robust and reliable multi-agent management for your complex workflows.
