n8n: the $2.5B glue gun — use it everywhere, just don't build the house with it
Self-hosted, fair-code, AI agent nodes — n8n hit a $2.5B valuation in months. Why it won, where it belongs, and the governance rule that comes with it.
🔗 n8n: the $2.5B glue gun — use it everywhere, just don't build the house with it.
The tool I was asked about most last year was not a model. It was n8n — the Berlin-built workflow platform that closed 2025 with a $180M round at a $2.5B valuation, NVIDIA on the cap table, revenue up 10x. For a "Zapier alternative," that is not hype money; that is infrastructure money.
What it is, in one line: visual workflow automation with AI agent nodes built in — a workflow can call models, run retrieval, and make decisions mid-flow. And critically: you can self-host it.
Why it won:
The data stays home. Self-hosted means everything runs inside your own boundary — in the year everyone asked "where does my data go," n8n's answer was nowhere.
Pricing that doesn't punish success. Per-task pricing makes your best workflows your most expensive ones. n8n broke that — finance noticed before IT did.
It sits at the citizen–developer border — visual enough for an ops person, code-friendly enough for an engineer. That border is where automation actually happens.
Where it belongs:
The glue layer — cross-system pipelines, scheduled AI jobs, "when X happens, enrich with AI, route to Y." Genuinely excellent here.
Not your deep agent platform — complex agent logic, custom retrieval, guardrails still belong in code. And in a Microsoft 365 shop, Power Automate stays the native surface for O365 flows. Portfolio decision, not religion.
The winning pattern: deterministic rails, with the LLM invoked only at genuine judgment points. n8n's canvas makes that discipline visible — quietly its best feature.
The caution: anything this easy to adopt gets adopted without asking. Workflows pile up holding production credentials, built by people who've changed teams — and self-hosting makes the security yours, not a vendor's. Three rules before it spreads (it's probably already there): a registry of who runs what, credential vaulting instead of pasted keys, and the same access reviews any integration platform gets.
One line to keep: n8n is glue, not the house. Use it everywhere things need connecting, govern it like infrastructure, and keep your deepest agents in code.
