TraceLoom v1.0 — Launch

Today we’re launching TraceLoom v1.0 — a BYOC platform for running distributed Playwright tests at scale in your own AWS infrastructure.

Your tests. Your cloud. Your data.

What’s in v1.0

BYOC Infrastructure

Tests run in your AWS account. Playwright traces, test results, and screenshots are written directly to your S3 bucket. Nothing leaves your cloud.

TraceLoom deploys as a CDK stack into your AWS environment — you own the infrastructure, the IAM roles, the networking, and the data.

Parallel Test Execution Across EC2 Spot Instances

Scale your Playwright suite across a fleet of EC2 Spot instances. TraceLoom handles fleet lifecycle — spinning up workers when a run starts, distributing tests across the fleet, and scaling back down when the run completes.

Spot instances run at 60-90% less than on-demand pricing. Test reruns are cheap, making Spot a natural fit for CI workloads.

Full Playwright Trace Capture and Storage

Every test generates a .trace.zip — the complete Playwright trace with timeline, network requests, console logs, and screenshots. Traces are uploaded to S3 automatically and viewable directly in the dashboard.

No more “it works on my machine.” Every failure has a full trace you can replay.

GitHub and S3 Test Import

Import your Playwright test suite from:

• GitHub: OAuth-based repository browser, branch selection, and automatic import
• S3: Upload a test bundle directly — drag and drop in the dashboard

TraceLoom auto-detects your Playwright config, installs dependencies, and configures execution environment.

Real-Time Fleet Monitoring with Cost Tracking

A live dashboard shows your active EC2 fleet: instance count, current spot price per instance, runtime, and estimated cost — updated in real time to four decimal places.

Cost transparency is a first-class feature, not an afterthought.

Smart Test Sharding

TraceLoom distributes tests across fleet workers using timing data from previous runs. The goal is equal wall-clock time per worker, not equal test count — so slow tests get their own workers and fast tests get batched.

Repository-Aware Execution

TraceLoom reads your repository structure to determine how to run your tests — which config file to use, which dependencies to install, which environment variables to set. Less configuration, more automation.
