AI agents you own.
Nodyn is an open-source AI agent runtime you own completely. It runs in your infrastructure, remembers your projects across sessions, and connects your tools — getting smarter every week. Not a library. Not a SaaS. A complete runtime you deploy and control.
Open source · Self-hosted · Your data never leaves your machine
Issue 2: Missing CSRF check on /api/webhook. Fixed → added origin validation.
2 files changed. Stored patterns to memory.
No re-briefing. No copy-paste. nodyn remembers your patterns across projects.
The problem
Every AI tool forgets you
the moment you close the tab.
You've explained your project architecture to ChatGPT. Then again. And again. You've re-pasted the same codebase context into Claude across a dozen sessions. You've rebuilt your agent setup from scratch every time you switch tools. It's not the AI that's the problem — it's that none of them persist.
And even the tools that try to remember you store that intelligence on their servers. Their pricing. Their API. Their roadmap. When the relationship ends — so does everything you taught them.
ChatGPT / Claude.ai
"Here's our project structure, the auth module uses JWT, the API layer…"
↳ Next session: explain it all again.
LangChain / CrewAI
Import 12 packages. Wire the chain. Define the graph. Write the glue code. Debug the prompts.
↳ A framework, not a runtime. Assembly required.
OpenAI Agents / Hosted AI
Your context, your patterns, your data — on their servers. Locked to their API. Their pricing.
↳ Vendor changes terms. You start over.
Your intelligence should compound, not reset.
SaaS AI rents you intelligence. Every session, you start from zero. Your context lives on someone else's server — and disappears the moment you stop paying.
- Knows nothing about your projects on day one
- Your data trains their model — not yours
- Vendor decides what it can do
- Subscription ends → intelligence gone
- One size fits millions of businesses
- ✓ Learns your projects from the first session
- ✓ Your data stays in your infrastructure
- ✓ You extend it exactly as you need
- ✓ Open source — yours forever
- ✓ Shaped entirely to how you work
Own your AI infrastructure.
A developer running agents across multiple projects without rebuilding context. A technical founder whose data pipelines run while they ship features. An engineer who deploys AI that actually learns their codebase. Nodyn makes this possible because it persists — and it's yours.
New project: re-explain the stack. Re-configure the tools. Re-teach the patterns. Copy-paste context between ChatGPT sessions. Lose everything when the tab closes.
✓ nodyn remembers your patterns across projects. Security audit on repo A? Same checks apply to repo B automatically. Memory compounds over time.
Manual data pulls, report generation, competitive monitoring. Every week, same steps, same tools, same context rebuilding.
✓ Define a pipeline once. nodyn runs it on schedule — pulling data, generating reports, storing results. Your context persists. Your pipelines improve.
Every hosted agent stores your data on their servers. Your prompts train their models. Your API key goes through their proxy. You have no idea what happens to your context.
✓ nodyn runs on your machine. Your memory stays in your filesystem. Your API key talks directly to Anthropic. Nothing leaves your infrastructure.
Honest comparison
Why not use an existing framework?
There are many ways to build AI agents. Most give you pieces. Nodyn gives you the whole runtime — ready to deploy.
| Tool | What it does well | What it can't do |
|---|---|---|
| ChatGPT / Claude.ai | Brilliant reasoning, instant results | Forgets everything. No persistent tools. No pipelines. No memory. |
| LangChain / LangGraph | Flexible agent framework, large ecosystem | A library, not a runtime. You assemble it. No built-in memory, CLI, or deployment. |
| CrewAI | Multi-agent orchestration | Prompt-chained roles. Hard to test. No persistent memory across runs. |
| OpenAI Agents SDK | First-party, easy to start | Vendor-locked to OpenAI. Hosted. Your data on their servers. |
| n8n / Zapier | Reliable rule-based automation | Can't reason. Can't adapt. Follows fixed rules, not goals. |
| nodyn | Complete runtime: memory, pipelines, tools, CLI, MCP server. Self-hosted. Yours. | Requires Node.js 22+ and an Anthropic API key. |

What it does
A complete runtime.
Not a library.
Persistent Memory
Multi-scope memory with RAG. Context survives every session — across projects, clients, and scopes. Stop re-explaining. Start building.
Autonomous Pipelines
DAG-based pipeline engine. Define steps once, run on schedule or on trigger. Sequential or parallel execution.
0+ Built-in Tools
Bash, filesystem, HTTP, memory, spawn, data store, web search, Google Workspace. Extend with MCP or custom tools.
MCP Server
Built-in Model Context Protocol server — stdio and HTTP SSE transport. Connect any MCP client. Expose nodyn as infrastructure.
CLI + Telegram
Full REPL with slash commands, markdown rendering, and diff views. Telegram bot for mobile access. Same agent, same memory.
Fully Self-Hosted
Your data never leaves your machine. Deploy via npx, Docker, or docker-compose. No SaaS. No middleman. Yours permanently.
Get started
