Functionize
Functionize is an AI-native test automation platform for enterprise web applications. Its Studio product uses autonomous agents to create and run end-to-end UI tests, with self-healing element resolution built on custom models rather than brittle selectors, across Salesforce, ServiceNow, Workday, SAP and bespoke apps.
- Attacks the real problem in test automation, which is maintenance rather than authoring
- Multi-attribute element resolution is a structurally sound answer to brittle selectors
- Coverage of Salesforce, ServiceNow, Workday and SAP targets genuinely hard cases
- ServiceNow appearing as a customer is a meaningful signal given the platform's difficulty
- Self-healing can adapt past a genuine regression, which is the inherent risk in the approach
- Tests built on a proprietary platform do not migrate to Playwright or Selenium
- All published outcome claims lack a stated baseline
Tusk
AI agent that writes tests for your pull requests Category: Coding & Development.

- Self-corrects rather than handing off broken tests

- Generated tests still need human inspection
