Amazon CodeGuru gives engineering teams automated code reviews and always-on profiling powered by machine learning. It flags performance hotspots, concurrency risks, and resource leaks during pull requests and in production, so defects are fixed before they become outages. Recommendations link to the exact lines that matter and explain tradeoffs in plain language. Integrations with GitHub, CodeCommit, and CI/CD fit existing workflows, while profiles and baselines show ROI over time.
CodeGuru Reviewer scans new changes for concurrency pitfalls, input validation gaps, resource leaks, and API misuses. It comments directly on diffs with context from similar patterns across repositories, which helps reviewers focus on design and edge cases. Findings include examples and links to documentation so fixes are quick. You can tune severity and rule packages per repo to align with internal standards, avoid noisy chatter, and keep feedback specific to your stack.
CodeGuru Profiler samples CPU time and memory allocations in production and staging to reveal methods that drive latency and cost. Flame graphs and anomaly views make it simple to spot tight loops, high-pressure allocators, and locks that throttle throughput. Compare profiles by release to verify optimizations and catch regressions early, then alert owners when thresholds are crossed so investigation starts before users feel impact. Cost estimates translate hot paths into dollars for planning.
Reviewer highlights risky patterns such as hard-coded secrets, credential misuse, and missing input sanitization. You decide which categories create blocking checks and which inform reviewers, raising the bar without paralyzing delivery. Combined with branch protection, this shifts effort toward higher-value design review. Audit logs record who dismissed or fixed findings so you can explain decisions during incident reviews or assessments, and guidance evolves as libraries and SDKs update.
CodeGuru integrates with GitHub, GitHub Enterprise, and AWS services so onboarding is straightforward. PR comments, checks, and badges appear where developers already work, and configuration-as-code keeps behavior consistent. APIs and webhooks route findings to chat or issue trackers for follow-up, while dashboards show trend lines that prove rules are working. Documentation and examples reduce setup friction so multiple teams adopt the same signal-first, low-noise review standards.
Profiler connects hotspots to AWS cost drivers, making it clear when CPU, memory, or I/O inefficiencies create spend. Recommendations explain safer pooling, batching, or algorithm changes with before-and-after expectations. Teams run experiments and compare traces to validate that changes lowered latency and usage, building a habit of continuous tuning rather than occasional firefights on visible services. Saved profiles create a playbook of proven fixes for your stack and languages.
Recommended for backend, platform, and SRE teams that want reviewers to focus on design while automation catches risky patterns. CodeGuru accelerates PRs, reduces regressions, and guides tuning with latency and cost context that leadership understands. Organizations adopting microservices gain consistent checks across repositories without inventing new tooling or standards for each squad, while startups and enterprises alike benefit from faster feedback loops and transparent performance baselines.
Manual reviews miss subtle concurrency and performance issues, and profiling often happens only after an outage. CodeGuru automates both: it flags defects during PRs and continuously profiles services to reveal code paths that waste time or money. Signals route to owners with clear remediation steps, and comparisons prove whether changes worked. The result is steadier deploys, lower infrastructure costs, and fewer firefights, with improvements that persist beyond the next release.
