Aider is an open-source AI pair programming tool that works in your terminal. It can edit multiple files, understand your git history, create commits, and works with virtually any LLM via API. Known for its practical approach to real-world coding tasks and excellent benchmark scores.
Hermes Agent is Nous Research's open-source autonomous agent, released in February 2026 under the MIT license. Its defining feature is a built-in learning loop: after completing complex tasks it writes its own reusable skills, improves them with use, and builds persistent cross-session memory of you and your projects. It runs self-hosted — from a $5 VPS to a GPU cluster — works with 200+ models, and is reachable from the CLI or 20+ messaging platforms including Telegram, Discord, Slack, and WhatsApp.
Aider and Hermes both run on Standard Compute
