## Code to Flow

Reading someone else's code — or your own code from six months ago — is one of the slowest parts of software work. Code to Flow compresses that process by turning a text snippet into a visual graph. The AI parses the structure and logic, then renders an interactive flowchart you can zoom, pan, and edit, with a parallel explanation panel describing the reasoning in words rather than symbols.

The tool goes beyond a single diagram type. Alongside control flow it can produce sequence diagrams for interactions, class diagrams for object structure, and user-journey views, which makes it useful both for debugging a gnarly function and for documenting architecture in a review or a spec. Diagrams can be exported as PNG, SVG, or PDF, and shared via a link.

Code to Flow runs entirely on pasted snippets and states that your code is never stored — it is processed to build the diagram and then discarded, which matters if you work under confidentiality constraints. The free tier covers three flowcharts per day, and a one-time or monthly upgrade removes the daily cap and ads. At the time of review the site reports more than 500,000 flowcharts generated.

**Pricing & Plans:** Freemium. Up to 3 flowcharts per day are free. Unlimited access is offered as a one-time lifetime purchase or a monthly subscription, both removing ads and raising the token limit. Prices are listed on the pricing page and may change.

- **Code-to-flowchart conversion:** Paste a snippet in Python, JavaScript, TypeScript, Java, C, C++, Go, Rust, and others to get an interactive diagram of its logic.
- **Multiple diagram types:** Generate flowcharts, sequence diagrams, class diagrams, and user-journey views depending on what you need to explain.
- **AI code explanations:** A written explanation accompanies each diagram so you can verify the AI's reading of the logic against your own.
- **Export and share:** Download results as PNG, SVG, or PDF, or share a link to the diagram with teammates and reviewers.

**Strengths:** Turns dense code into a readable visual in seconds rather than minutes of manual tracing; Supports the common programming languages and several diagram types in one tool; Explanations make the diagram self-checking rather than an opaque picture; States that code is never stored, which suits confidential work; free tier available

**Limitations:** Very large files may exceed the token limit on lower tiers; No interactive editor for deep diagram customization beyond basic edits; The daily free cap of three flowcharts is limiting for heavy use

## 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
