Finally, a GUI for certificate management. No more checking if CertBot actually ran. CertKit gives you one dashboard to see every cert, every renewal, every domainโ€”before they expire and ruin your weekend. Built after the third production outage from a failed ACME challenge that nobody noticed.

Just point a DNS CName at us, and weโ€™ll automatically discover, provisioning, validation, renewal, and deployment of certificates. Through an actual UI that can be easily monitored. Supports wildcards, multi-domain, whatever complexity you've accumulated over the years. No DNS API keys to leak. No cron jobs to debug. No Kubernetes required.

Built by the TrackJS team who are known for building simple and reliable tools that Just Workโ„ข๏ธ.

CertKit is free while in beta. Help us shape the future of SSL Certificate Management.

CertKit.io features and specs

  • SSL Certificate Discovery
    Automatically find all the certificates from your domain
  • SSL Certificate Lifecycle
    Request, renew, and remove certificates without code changes or command line
  • SSL Certificate Monitoring
    Know which certificates are running on which hosts, and get alerts if anything is going to expire.

Selenium in AWS Lambda features and specs

  • Scalability
    AWS Lambda automatically scales your Selenium tests by running multiple instances simultaneously, allowing for efficient parallel testing without managing servers.
  • Cost-effectiveness
    With AWS Lambda, you only pay for the compute time that you consume, which can significantly reduce costs compared to traditional server-based deployments, especially for occasional testing.
  • Maintenance-free
    AWS Lambda abstracts away server maintenance, updates, and patch management, allowing you to focus exclusively on writing and executing Selenium tests.
  • Integration with AWS Services
    AWS Lambda integrates seamlessly with other AWS services such as S3, DynamoDB, and API Gateway, enabling you to build comprehensive, cloud-native testing workflows.

Possible disadvantages of Selenium in AWS Lambda

  • Execution Time Limitations
    AWS Lambda imposes a maximum execution time limit (15 minutes as of 2023), which may not be sufficient for running extensive Selenium test suites.
  • Cold Start Latency
    When Lambda functions are not frequently invoked, they can experience latency during cold starts, potentially affecting the performance of Selenium tests.
  • Browser Environment Setup
    Running Selenium in AWS Lambda requires setting up browser binaries in a serverless environment, which can be complex and may require custom Lambda layers or container images.
  • Resource Limitations
    Lambda functions have restricted memory and computing capabilities, which might limit the execution of resource-intensive Selenium tests.

Analysis of Selenium in AWS Lambda

Overall verdict

  • Selenium.cloud offers a convenient way to run Selenium-based browser automation on AWS Lambda, providing a serverless, cost-effective, and scalable solution for teams that need occasional or bursty web scraping and testing capabilities without managing dedicated infrastructure.

Why this product is good

  • Serverless architecture eliminates the need to provision or maintain servers for running browser automation
  • Pay-per-use pricing model can significantly reduce costs for intermittent or low-volume automation tasks
  • Automatic scaling handles concurrent execution spikes without manual intervention
  • Simplifies deployment of Selenium scripts by packaging Chrome/Chromium binaries compatible with Lambda's environment
  • Reduces DevOps overhead compared to maintaining Selenium Grid or dedicated VM-based testing infrastructure
  • Integrates well with other AWS services like S3, CloudWatch, and API Gateway for building complete automation pipelines

Recommended for

  • Teams running periodic or scheduled web scraping jobs
  • QA teams needing occasional automated browser testing without maintaining persistent infrastructure
  • Startups and small teams looking to minimize infrastructure costs for browser automation
  • Developers building serverless web scraping or monitoring tools
  • Projects with unpredictable or bursty automation workloads that benefit from auto-scaling
  • Users already invested in the AWS ecosystem seeking tighter integration with existing services
