Aura
The Git-native semantic layer that makes AI coding agents safe to ship
Overview
Aura is an open source, Git-native tool built for a world where AI agents write a growing share of your code. Instead of diffing text like Git does, it hashes the abstract syntax tree of your code, so it can tell the difference between a real logic change and a cosmetic one. When an agent claims it only touched three functions but actually modified a fourth, Aura catches the mismatch before the commit goes through, and lets you revert just the broken piece instead of the whole file.
It's aimed at teams already relying on Claude Code, Cursor, or Copilot at scale: monorepo teams tired of merge churn, regulated industries that need an audit trail for AI-written code, and open source maintainers trying to filter low-quality AI pull requests. The core engine is free and open source under Apache 2.0, with a paid enterprise self-hosted tier planned but not priced publicly yet, so this is still an early-stage tool without a long track record.
Key Features
AST-Based Tracking: Parses code into an abstract syntax tree instead of reading raw text, so it understands logic, not just lines.
Intent Verification: Cross-checks an agent's stated intent against what it actually changed, and flags mismatches before a commit lands.
Function-Level Recovery: Roll back a single broken function or class without touching the rest of the file.
Multi-Agent Coordination: Lets multiple AI coding agents work on the same codebase with less context needed per handoff.
Self-Hosted Mode: "Mothership Mode" runs fully on-premises with no cloud dependency, for teams with data sovereignty requirements.
Audit Trails: Cryptographic proof of what changed and why, useful for regulated industries.
Pricing
Starting price
Free (core engine is open source under Apache 2.0; enterprise "Sovereign Vault" tier pricing is not public yet)
Core Engine: Free. Open source under Apache 2.0, installable via a one-liner or Cargo, no usage limits.
Sovereign Vault (Enterprise): Pricing not published. Planned self-hosted enterprise tier.
Disclaimer: pricing may change, confirm on Aura's own site before buying.
Pros
Free and Open Source: The core product has no paywall, feature gates, or usage limits.
Runs Locally: No cloud dependency required for the core engine, good for privacy-conscious teams.
Solves a Real, New Problem: Purpose-built for the specific mess of multiple AI agents committing code without oversight.
Cons
Very New: Recently launched with limited independent reviews or long-term production track record.
Narrow Language Support: Reliable AST parsing is currently strongest for TypeScript/JS, Python, and Rust, not every language.
Adds Setup Overhead: Another layer on top of Git that a team has to learn and maintain alongside existing workflows.
Enterprise Pricing Unclear: The paid tier for teams that need it most isn't public yet.
What Makes It Unique
Semantic, Not Text-Based, Version Control: Unlike Git itself, Aura understands code as logic (AST hashes) rather than lines of text, which is what lets it verify an AI agent's stated intent against its actual change.
