Sandstone vs n8n: Build It Yourself, or Buy the System?
n8n is a capable workflow engine — node-based, self-hostable, with AI agent nodes and connectors into most things. Plenty of legal teams have built on it. The question isn't whether legal automation can be built there. It's which parts of the system you want to own and maintain, and which you'd rather buy.
Sandstone vs n8n
| Capability | Sandstone |  n8n |
|---|---|---|
| What it is | AI-native operating system for in-house legal work | General-purpose workflow automation engine |
| Built for legal | Purpose-built for in-house legal, by lawyers and legal engineers | General-purpose; legal workflows are built by you or a partner |
| Legal context out of the box | Counterparty history, prior decisions, and playbooks derived from your own contracts | Built to your specification |
| Intake and triage | Structured intake with agents that interpret intent and route with context | Triggers and nodes you configure |
| Workflows and approvals | Built step by step, with approval gates, on a platform maintained for you | Fully configurable, built and maintained by your team |
| Permissions across systems | Permissions mapped across every connected integration | Whatever you implement per connection |
| Reporting | Cycle time, risk exposure, capacity, and deviation rates | Built to your specification |
| Ongoing maintenance | Maintained by Sandstone as part of the platform | Maintained by your team |
| Best fit for | Legal teams that want the system rather than the build | Teams with engineering capacity and a preference for owning the stack |

Frequently asked questions
You can build a lot of it, and the first version usually works. The cost shows up later: keeping connectors alive as APIs change, handling the request that doesn't match any node, proving to security how permissions resolve across three systems, and the day the person who built it moves on. Sandstone is that maintenance as a product rather than a headcount.
Legal context out of the box — playbooks derived from your own contracts, counterparty history, prior decisions — plus contract execution and a system of record. An automation engine moves work between systems; it doesn't know what your team decided about this counterparty last year.
No. Sandstone integrates with the systems around it, and plenty of teams keep automations for things outside legal. The argument isn't that you should never build — it's about which parts are worth owning.
Tell us the requirement early. Self-hosting is a legitimate reason teams choose an automation engine, and if it's a hard constraint for you we'd rather scope it honestly up front.
