## What it is
LambCI is a serverless continuous integration system built on AWS Lambda that runs tests when code is pushed or pull requests are opened on GitHub. It is deployed as a CloudFormation stack, integrates with Slack, and updates GitHub commit statuses, in the vein of Jenkins, Travis, or CircleCI.

## Use cases
- run CI builds on AWS Lambda without maintaining build servers
- run tests on GitHub pull requests and pushes
- get zero-cost CI when not building
- run 1000 concurrent builds out of the box
- integrate CI with Slack notifications and GitHub status checks
- deploy a CI system via CloudFormation

## When to choose
- you want serverless CI with no servers or databases to maintain
- your builds fit within Lambda's environment and limits
- you want pay-per-use CI with zero idle cost
- you're heavily invested in AWS and want easy integration with AWS resources

## When to avoid
- you need long-running builds or full Docker-based build environments
- you need the latest language runtimes out of the box
- you want an actively developed CI tool (repo is in maintenance mode)
- you prefer GitHub Actions or a hosted CI service

## Facets
- artifact type: service
- maturity: maintenance
- function: ci-cd, testing, serverless, deployment, cloud
- domain: testing, cloud-computing
- platform: cloud, serverless, self-hosted
- tags: aws-lambda, continuous-integration, github-integration, serverless-ci, cloudformation, devops, automation
