Stop scrolling CloudWatch line by line.
LogStitch is a native macOS app for AWS Lambda developers. It reads the request ID stamped on every CloudWatch log line and stitches them back into the invocation they belong to — so you can read a single Lambda execution as one coherent story instead of a timestamp-sorted river of interleaved streams.
Built for AppKit speed. Local-first. No cloud component. Your logs never leave your Mac.
WHY LOGSTITCH
CloudWatch interleaves log lines from every concurrent execution into one stream. LogStitch groups them by request ID, surfaces cold starts and platform events, parses embedded JSON, and gives you the full invocation — duration, memory, billed cost, status — at a glance.
Cached locally in SQLite, every log line you've ever fetched is one keystroke away. Forever. Offline.
WHAT IT DOES
• STITCH — Group every CloudWatch log line by request ID into a single, readable invocation. Cold-start flags, REPORT-line metrics, parsed JSON and platform events surface automatically.
• CORRELATE — Follow a request across functions, accounts and regions in a swim-lane timeline. See propagation latency between hops and which function originated the error.
• ANALYZE — p99 trends, cold-start scatter, memory right-sizing recommendations, working monthly cost projection. No separate dashboards, no PromQL.
• DETECT — Error log lines with the same message template auto-cluster into patterns with lifecycles and impact scores. Statistical anomalies (≥2σ / ≥3σ) on duration, errors, cold starts and cost surface themselves before customers do.
• LIVE TAIL — Real-time streaming on any function. Completed invocations save automatically to your local history.
• MCP SERVER FOR CLAUDE — Built-in Model Context Protocol server lets Claude Desktop (and any MCP-aware AI tool) search your logs, drill into invocations, and run statistical analysis. Your AWS credentials never leave the Keychain.
AWS PROFILES, DONE RIGHT
Imports your existing ~/.aws/config and credentials. Supports Static Keys, SSO (OIDC device flow), and Assume Role chains. Credentials validated via STS before save. Color-coded workspace tabs and a ⌘⇧P profile switcher. Live session countdown with one-click refresh.
THE BORING DETAILS, DONE RIGHT
• SQLite FTS5 full-text search over every cached log line
• Field-aware filters with auto-complete on discovered JSON keys
• Pin JSON fields as columns in the invocation list
• Background sync with per-function intervals and a daily CloudWatch API cost budget
• Jira Cloud and GitHub issue-tracker integration with templated bodies and live status polling
• JSON, CSV and plain-text export with field selection
• Online-backup snapshots and 30-day backup reminders
PRIVACY
No LogStitch backend. No third-party analytics on log content. No telemetry that includes your data. The app talks to AWS, your local SQLite database, and any issue tracker you've explicitly connected — nothing else.
Credentials live in the macOS Keychain. Logs live on your disk. You own both.
REQUIREMENTS
macOS 26.1 or later.
Free 14-day trial — no card, no account, no telemetry.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Fixes and refinements across issue tracking and memory analysis.
• Fixed a crash that occurred when connecting a Jira or GitHub account.
• The Create Issue form now reads each Jira project's own configuration: issue types and priorities come from the selected project, fields the project doesn't use are hidden, and required fields are flagged before you start writing.
• Jira and GitHub now report the actual reason a request was rejected instead of a generic authentication error.
• The memory utilization chart adds a p99 line, fills the available space, and no longer clips its labels or hover tooltip.
• The main window keeps the size you gave it when opening and closing a profile, and the compact/expanded list setting is remembered between launches.
• The configuration-change badge now keeps its before/after values, and the storage capacity banner clears as soon as you resolve it.
