AgentDiff vs. Maestro
Maestro and AgentDiff both give engineering leaders visibility into AI, but at different layers. Maestro analyzes engineer behavior — how people use AI — and presents it in a SaaS dashboard. AgentDiff records the artifact — which agent changed which lines — signs it, stores it in git, and can block a merge on policy. One tells you how AI is used; the other tells your PR gate what AI changed and whether it is allowed.
At a glance
| AgentDiff | Maestro | |
|---|---|---|
| Core job | What the AI changed + merge gate | How engineers use AI (behavior analysis) |
| Unit of record | Signed line-level authorship records | Usage and session analytics |
| Where data lives | Your git history (git-native) | Hosted SaaS dashboard |
| Tamper-evidence | ed25519-signed | Not the focus |
| Enforcement | Blocks merge on policy violation | Reporting / visibility |
| Primary buyer | Platform, security, compliance — wants a gate + evidence | Engineering leadership — wants a usage dashboard |
Behavior analytics vs. artifact evidence
Maestro's strength is understanding engineering behavior — turning AI usage into session-level insight for leaders. That is a dashboard buyer's tool. AgentDiff's strength is the artifact: a signed, git-native record of what an agent actually changed, and a gate that can block the merge when policy is violated. That is an evidence-and-enforcement buyer's tool.
If your question is "are my engineers using AI well?", that is Maestro's job. If your question is "which agent wrote this line, is the record signed, and is this change allowed to merge?", that is AgentDiff's job.
Data sovereignty
AgentDiff stores its records in your own git remote, signed with keys you control — no source code or authorship evidence is held in a vendor database. For teams where data sovereignty and audit-grade evidence matter, that git-native model is the deciding difference.
Frequently asked questions
What is the difference between Maestro and AgentDiff?+
Maestro analyzes how engineers use AI and presents it in a hosted dashboard. AgentDiff records what the AI changed as signed, git-native provenance and can block merges on policy. One is usage analytics; the other is artifact evidence plus enforcement.
Can I use both Maestro and AgentDiff?+
Yes. They address different questions — usage behavior versus authorship evidence and policy enforcement — so they can coexist. AgentDiff is the layer that produces a signed record and a merge gate.

AgentDiff records which agent wrote which line, signs it, and keeps it in your git history. Open the live dashboard or book a walkthrough.
