Know before you merge - ChangeLens

ChangeLens analyzes real repositories to surface the true downstream impact of a code change, so you can merge with confidence instead of guesswork.

Hidden Cost of Simple Changes

Small changes have outsized consequences and can ripple through entire codebases

The Reality of Modern Dev

Why code reviews feel like a gamble

  • !

    Bugs surface far from the change

    Failures appear in distant components due to shared utilities or dependencies.

  • !

    Change impact is discovered too late

    Teams only understand the consequences after changes reach staging or production.

  • !

    Review confidence is low

    Pull requests stall because reviewers cannot confidently predict what might break.

  • !

    Fear replaces informed decisions

    Teams avoid refactors and improvements due to unknown downstream effects.

ChangeLens Insight
Scaling codebases requires more than human memory.

Risk does not live in the lines that change, but in the dependencies and execution paths they influence.

Modern systems behave through interactions, yet reviews focus on files in isolation.

Without shared visibility into impact, teams rely on incomplete mental models.

Late discovery turns small mistakes into expensive debugging, rollback, and recovery efforts.

Built for the Agentic Era

Powered by Gemini 3, ChangeLens employs a multi-agent reconciliation loop to ensure every architectural hypothesis is grounded in actual code reality.

Agent 1: Impact Scan

Utilizes Gemini 3's 1-million token context window to ingest entire repository tree. It builds a structural model to predict the 'Blast Radius' without losing state.

Agent 2: Code Audit

Uses Gemini 3's SOTA reasoning to fetch and audit file contents. It acts as the 'Grounding' agent, explicitly verifying imports to eliminate hallucinations.

Agent 3: Planner

Employs Gemini 3's chain-of-thought planning to reconcile structural hypotheses with verified code, producing an impact report to ensure reliable deployments.

Features built for real Codebases

Designed to reveal real change impact, reduce review risk, and improve decision-making

In-Browser Change Impact Analysis
Analyze a proposed change directly from a GitHub repository URL without cloning or server-side processing. Everything runs in the browser.
Multi-Agent Impact Reasoning
Three specialized Gemini-3 agents analyze change to identify affected files, hidden dependencies and reconcile findings into report.
Risk Levels & Confidence Scores
Each impacted file is annotated with risk level and confidence score, helping you prioritize what needs careful review before merging.
Exportable Impact Checklist
Export the analysis as structured JSON format to use as a verification checklist in reviews, testing, or CI workflows before deploying.
