Formfilled empowers marketing teams with the ability to enrich every form submission with key attribution details like UTMs and URL history. This data can be easily routed into CRMs and your existing tech stack, giving you a clear vision of ROI on marketing channels, campaigns and website content. The tool tracks both first-touch and last-touch attribution and enriches form submissions with these details via hidden fields.

Formfilled is quick and easy to set up. In our browser-based dashboard, you can choose which attributes you’d like to track, select your website form platform or CRM provider, and define custom traffic channel groupings to categorize traffic to your liking. From there, you can easily implement your script via Google Tag Manager, HTML, or your website's fileservers. Formfilled is hosted on a first-party basis and there is no outside visibility into your lead or CRM data, ensuring your organization’s privacy and security.

Once Formfilled is configured, you'll be able to consistently send attribution data to your marketing automation platform, CRM,= and notification workflows to analyze where leads, opportunities and customers originated from.

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.
