Every product started as a tool we needed ourselves.

Open-source packages, free desktop utilities, SaaS products, and apps — released, maintained, and used in our own work before anyone else's.

For Agents & Developers

Agentic AI

Infrastructure and tooling built for AI agents and the people building with them — shared memory, reusable skills, and cost visibility.

Python · PyPI
v0.4.2

hermes-memory-pgvector

A Postgres + pgvector memory provider plugin for hermes-agent — durable, semantically-searchable shared memory for a fleet of agents, with hybrid vector + full-text recall and no LLM in the hot path. Installs from PyPI in two commands on any hermes-agent host.

Shared fleet memory
Durable, searchable store with per-agent themes and attribution.
Hybrid recall (RRF)
Fuses HNSW vector search with Postgres full-text via Reciprocal Rank Fusion.
Pip-native install
pip install, then one command generates the plugin discovery shim.
No LLM in the hot path
An async writer keeps memory writes off the critical path.
pip install hermes-memory-pgvector && hermes-pgvector install

Claude Code · Skills
v1.6

agent-skills

A personal collection of agent skills for Claude Code and other LLM agents — reusable instruction sets that prime the agent so you don't re-explain the same context every session.

Reusable instruction sets
Each skill primes the agent with a domain's knowledge.
Workflow patterns
Encodes the right steps and order for real tasks.
Failure playbooks
Anti-patterns and recovery paths the agent would miss.
Install one or all
Add a single skill or the whole set from skills.sh.
