## Hermes-Agent

Hermes-Agent is the officially published agent from Nous Research, distributed free and open source under the MIT license. Rather than a single chat window, it is designed as a long-lived assistant that persists conversations, memories, and self-authored skills between sessions, so solved problems become reusable capabilities instead of one-off prompts. The desktop app and install script support macOS 12+, Windows 10/11, and most Linux distributions.

Its reach is deliberately broad. One agent and one shared memory can connect to Telegram, Discord, Slack, WhatsApp, Signal, email, and the command line, so the same assistant follows you across surfaces. Beyond conversation it can browse and automate the web, use vision, generate images and speech, and reason across multiple models, while isolated subagents handle delegated work with their own terminals and Python RPC scripts to keep the main context light.

Automation and safety are first-class: natural-language scheduling runs recurring reports, backups, and briefings unattended through the gateway, and sandboxing is available across five backends including local, Docker, SSH, Singularity, and Modal with container hardening and namespace isolation. The core agent is free; model providers and optional hosted services are billed separately, and Nous Portal offers usage-based cloud agents in addition to free and low-cost tiers.

**Pricing & Plans:** The Hermes-Agent software is free and open source under the MIT license; model providers and optional hosted services are billed separately. Nous Portal offers a free pay-as-you-go tier plus Plus, Super, and Ultra cloud plans with usage, hosted tools, and cloud hosting, so you can bring your own keys or pay for managed credits.

- **Persistent memory and self-written skills:** Hermes keeps conversations, memories, and skills between sessions, and turns solutions it has already found into reusable capabilities you can call again.
- **Every surface in one agent:** Connect Telegram, Discord, Slack, WhatsApp, Signal, email, and the CLI to a single agent with one shared memory, so context follows you across platforms.
- **Natural-language scheduling:** Describe recurring reports, backups, or daily briefings in plain language and let them run unattended through the gateway.
- **Subagent delegation:** Spawn isolated subagents with their own conversations, terminals, and Python RPC scripts to run zero-context-cost pipelines in parallel.
- **Flexible sandbox backends:** Run untrusted work in local, Docker, SSH, Singularity, or Modal environments with container hardening and namespace isolation.

**Strengths:** Genuinely free and MIT-licensed, with no mandatory subscription to use the core agent; Persistent memory and auto-generated skills make it compound in usefulness over time; Unusually wide platform reach for a single agent, from Telegram to the command line; Multiple sandbox backends and subagent isolation suit serious automation work

**Limitations:** Self-hosting and provider setup demand real technical comfort compared with hosted chat apps; You bring your own model provider keys or pay for Nous Portal credits, so costs vary; Cloud hosting capacity per tier is modest, which can limit heavy always-on workloads

## OpenFlowKit

OpenFlowKit is an open-source diagramming studio built for engineers who think in systems. It supports three ways of working on one canvas: freehand drawing with shapes, connectors, ink, images and charts; writing the diagram as code in Mermaid, D2 or Structurizr; or letting an AI agent build and edit it live through the Model Context Protocol. Text and canvas stay in sync, so you can start with a snippet and finish with something visual.

A standout v2 feature maps a public GitHub repository directly in the browser: paste an owner/repo URL and OpenFlowKit reads the files, produces boxes and connections, and cites each arrow back to the exact line of code it came from. Private repositories can be mapped locally through the CLI. The result is architecture documentation that reflects the code rather than someone's memory of it.

OpenFlowKit is also practical for day-to-day diagramming: a toolset of 29 MCP tools for agents, C4 context/container/component views that stay connected to one underlying model, automatic matching of 2,000+ cloud and developer icons by node label, animated SVG/GIF/MP4 export, share links and self-hosting. It is MIT licensed, runs locally by default and needs no account.

**Pricing & Plans:** Free and open source under the MIT licence. There is no paid tier on the site; you can start creating without signing up, and the code can be self-hosted.

- **Repo-to-map generation:** Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
- **Agent-native canvas over MCP:** 29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
- **Diagram as code:** Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
- **Connected C4 model views:** Move from system context to containers to components in linked views that all stay grounded in a single architecture model.
- **Icon matching and motion export:** Label a node 'PostgreSQL' or 'Kubernetes' and the right icon is matched automatically from 2,000+ cloud and developer icons; export animated SVG, GIF, MP4 or WebM for living documentation.

**Strengths:** Free, MIT-licensed and local-first with no account required; Unique repo-to-diagram mapping that cites each connection back to code; Works equally well for hand drawing, diagram-as-code and AI-agent workflows; Strong ecosystem coverage with automatic matching of 2,000+ cloud and developer icons

**Limitations:** No hosted paid support or managed cloud option is advertised, so teams self-host; Advanced MCP and CLI repo mapping assumes comfort with developer tooling; C4 model depth and multiple views can feel heavy for quick one-off sketches
