Cloud Agent Orchestration
Run dozens of agents in parallel without babysitting them. Every agent writes code and verifies its own work in an isolated sandbox.
Self-driving PRs
Murmur listens to GitHub and automatically deals with code review comments, failing checks, and merge conflicts.

Sandboxed
Each agent runs in a dedicated cloud VM that can run your full stack. This allows agents to self verify their work, and to run longer since they're untethered from your local machine.

What makes our code review different?
We combine an agentic pipeline with purpose-built Abstract Syntax Tree (AST) walkers that we’ve built for the most common programming languages. This allows our agent to deterministically gather rich context about every change, without relying solely on an LLM to search for that context itself. The result is faster, more token-efficient analysis and a deeper understanding of the codebase. This is one reason we achieve higher precision at 1/20th the cost of Claude’s Code Reviewer, according to independent benchmarks. On Martian’s benchmark, read 9 September 2026, 79.5% of Macroscope’s suggestions matched a change the developer actually made, against 69.4% for Claude.

Fix Shopify route page title fallbacks
PR #1738 · OpenJordan wants to merge intomain
Summary
This PR fixes checkout titles for Shopify routes whose projected slug is flattened before the title resolver runs.
- Adds
resolveRouteTitleFallbackto recover store titles when a route exists but the generic resolver returns an empty value. - Keeps non-Shopify routes on the existing title resolution path.
- Adds coverage for flattened slugs, nested product paths, and missing store metadata.
Start review in src/routes/titleResolver.ts, where the fallback is applied after projection.

Removes the settlementDate guard from invoice replay. Paused accounts can now be charged twice when the retry job replays a partial billing window.

Parag AgrawalCEO, Parallel
We are huge fans. It's the best code review tool we've tested and I personally love that we can avoid unnecessary status update meetings.
Scott BelskyCofounder of Behance @ Founder A24 Labs
Macroscope has become a core part of our engineering team, bringing some new superpowers in productivity and keeping us all aligned and up to speed on what's getting done every day.
Kaz NejatianCEO, Opendoor
I filed a minor bug with @Macroscope at 9 am London time. By 3 pm London time (7 am SF time!) @kayvz personally responded and was fixing it. Founder mode.
Logan FisherCPO & CTO, Parkhub
Macroscope just gets it. They've cracked the code on turning huge amounts of complex data into clear, actionable insights-and they've made it effortless for us to make smarter decisions, faster.
Shane MacCEO, XMTP Labs
Rarely do I see a product that helps everyone in the org save time and do more without asking us to do more. The team does less updating while leadership can see what's actually happening - and even ask questions about it - all without distracting anyone.
Michael YorkCEO, Casa
Macroscope's commit summaries – drawing from their deep understanding of our projects and codebase – are the beating heart of our engineering organization. The kind of upgrade you can never imagine working without.
Nick MolnarCTO, XMTP Labs
We've used just about every AI-driven PR assistant out there: the signal to noise from Macroscope is the best I've seen. The PR descriptions are better than what we would have written by hand, and when it flags an issue it's almost always a real bug.
Hardik PatilProduct Lead at Anon
Macroscope makes it easy for me to stay on top of engineering progress and developer productivity, even as a solo product lead working with 8 engineers. Their support is ridiculously responsive, and they're super fast at shipping new features I requested.
Marcel MolinaCTO & Cofounder, Particle
Macroscope is like having a distinguished engineer tech lead who's read every diff, understands every project, and can answer any question about your codebase instantly. We can finally focus on shipping instead of process.
