Say yes to AI coding org-wide, with the audit evidence to prove it was governed.
StackRails gives AI coding agents permission-gated access to your Architecture Graph, never trains a model on your code, and produces an exportable record of what was generated, checked, and merged. So your security team can approve AI coding across every team and show how it was governed.
Built for your security review.
Never trains on your code
Your code and architecture are never used to train a model, ours or anyone else's.
Permission-gated, two-tier
Every query is resolved against the user's source-control permissions. Tier A architectural metadata (services, dependencies, ownership) and Tier B code-internal content are gated separately. Identity is bound through SCIM.
Your tenancy
Hosted in the EU, in your VPC, on-prem, or air-gapped. The only egress is the MCP response to the AI coding agent your developer already uses.
An exportable record
Every generation, conformance check, and merge decision is recorded and exportable, so you can show how AI-generated code was governed across every team.
Safe AI coding at scale
Roll out AI coding tools across your entire organisation without the risk. Gated by your permissions, and it never trains a model on your code. The guardrails that make enterprise-wide AI Coding Governance possible. Your security team signs off. Your developers get productive.
Your rules, before and after your AI agents write
Your AI coding agents get your rules before they write. Then StackRails checks the code against the same rules and reports what breaks one, on the pull request too.
Before the agent writes
Context and policy go into the agent's prompt, so the first pass is steered toward compliant code.
On the developer's machine
Your AI coding agent's output is checked on the developer's machine, before code is committed or pushed.
At the pull request
Check results are reported on the pull request as a conformance report, with an audit record for the architect's review.
In your environment. Gated by your permissions. Fast to deploy.
StackRails deploys in your own cloud (AWS, Azure, or GCP), hosted in our EU region under your KMS, or fully on-prem. In your own cloud or on-prem, your source never crosses a tenancy boundary. On the hosted EU option, only the architecture model (metadata, under your KMS) is managed by StackRails, never your source.
Your cloud
Run StackRails in your own cloud: AWS, Azure, or GCP. Your access role, your VPC, your KMS. Your source stays in your environment; the only egress is the MCP response to the AI assistant you already use.
Hosted EU
StackRails-managed in eu-north-1 (Stockholm) under your KMS. Enterprise posture without the infrastructure overhead.
On-prem / air-gapped
Self-host the full stack. No external dependencies beyond the embedding model. Air-gapped capable, suited to sovereign-cloud deployments.
StackRails is not itself a certification. It produces the evidence your auditors and assessors ask to see.
