brain0 vs Poolside AI
Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | brain0 | Poolside AI |
|---|---|---|
| Pricing | Free (open-source) | Contact sales (enterprise) |
| Deployment | Offline-first, local CLI | On-prem, VPC, workstation (defense only) |
| Core Capability | Passive decision graph linking commits to AI prompts | Custom foundation models + multi-agent orchestration |
| Context Length | Not specified (local LLM support) | 256K tokens |
| Best For | Teams needing AI audit trails and provenance | High-consequence, regulated enterprises |
| Setup | One command: npx brain0 up | Vendor engagement + embedded engineers |
If you're a regulated enterprise needing custom AI models and agents for complex, high-stakes software engineering with full governance, Poolside AI is the only choice — but be ready for a sales process and significant budget. For teams that already use AI coding assistants and want lightweight, offline audit trails, drift detection, and signed provenance, brain0 is free and instantly useful. They solve different problems: one builds AI for you, the other watches the AI you already use.
brain0 is an open-source decision graph that links every git commit to the AI agent prompts behind it.

Frequently Asked Questions
brain0 vs Poolside AI: which should you choose?
If you're a regulated enterprise needing custom AI models and agents for complex, high-stakes software engineering with full governance, Poolside AI is the only choice — but be ready for a sales process and significant budget. For teams that already use AI coding assistants and want lightweight, offline audit trails, drift detection, and signed provenance, brain0 is free and instantly useful. They solve different problems: one builds AI for you, the other watches the AI you already use.
Can brain0 be used without Node.js?
No, brain0 requires Node.js ≥20 for its one-command setup.
Does Poolside AI offer a free trial?
No, Poolside AI is enterprise-only with contact sales pricing; no self-serve signup or trial is mentioned.
Can brain0 track agents other than Codex and Claude Code?
brain0 auto-discovers Codex and Claude Code sessions, but its passive approach may work with other agents if they run in a compatible environment.
Does Poolside AI integrate with existing version control?
Poolside's data connectors include repos, but the platform is designed to be the AI layer; it doesn't passively audit existing agents like brain0 does.
Is brain0's data stored in the cloud?
No, brain0 is offline-first by design; no data egress occurs unless you explicitly configure something else.
What does 'two-dimensional risk score' mean in brain0?
It combines likelihood and impact of risk from AI-generated changes, visualized green to red, based on drift and DLP findings.
Can Poolside AI be deployed on air-gapped networks?
Yes, Poolside supports on-prem and VPC deployment, and for defense customers, workstation deployment — all suitable for air-gapped environments.
Do I need a local LLM for brain0 to work?
No, brain0 works without a local LLM; LLM-based summaries and search are optional via Ollama.
