CodeStream
Know What Your Coding Agent Actually Built

Stop blindly trusting
agent-written code.

Autonomous coding agents can produce thousands of lines in seconds. CodeStream analyzes the full architecture, pinpoints concrete risks, generates narrated audio briefings, and answers your questions with source-cited precision.

Architecture & Components

React is structured around a declarative component model decoupled from execution targets. Core reconciliation logic coordinates fiber trees, lane prioritization, and work loops.

Audited Risks

  • high
    Unhandled error boundary propagation

    Async lane transitions can bypass top-level recovery boundaries under heavy thread load.

    packages/react-reconciler/ReactFiberWorkLoop.js
  • medium
    Fallback scheduler starvation

    Timer resolution degrades under nested microtasks.

Built for the age of autonomous coding agents

Everything you need to review, understand, and trust agent-generated code before shipping.

🗺️

Codebase Guided Tours

Dissect entire repositories in minutes. Get clear architectural summaries, component responsibility breakdowns, data flow paths, and prioritized reading orders for human reviewers.

🔍

Commit & PR Audits

Inspect ranges of commits and diffs with surgical precision. Automatically catch modified manifests, untested files, breaking changes, and an interactive "Before You Trust It" checklist.

🎙️

Narrated Audio Briefings

Listen to your code briefings like a podcast on your commute or during breaks. Scripts are written for the ear and voiced by ElevenLabs with instant playback and scrubbing.

💬

Grounded Q&A with Citations

Ask questions directly about any finished cast. Responses are grounded in Voyage AI code embeddings and strictly cited against real files and function signatures—no hallucinations.

Security by Design: Zero-Leak Redaction

CodeStream deterministically scans for credential files (.env, private keys, certificates, service accounts) and quarantines them. They are never sent to the LLM, and are instead flagged directly in your audit report.

Enterprise Workflow Reliability

Powered by Temporal distributed workflows. Ingestion, model calls, and voice synthesis ride out rate limits and provider hiccups with resilient exponential backoffs and durable state machines.

How CodeStream Works

From git repository to actionable briefing in three automated steps.

01

Connect Your Repository

Paste any public or private GitHub repository URL. Choose a branch, commit SHA, or diff range.

02

Multi-Agent Deep Analysis

Mastra AI agents running Google Gemma 4 read, summarize, and synthesize code chunks with strict grounding.

03

Listen, Inspect & Interrogate

Stream the narrated audio, review concrete risks, and ask technical questions with verified citations.

Stop guessing what your agent changed.

Start listening to your codebase and review pull requests with complete confidence.
