Confident AI
LLM evaluation and observability from DeepEval makers Category: Coding & Development.
- Backed by the popular open-source DeepEval
- Broad evaluation, observability, and red-teaming
- Enterprise-grade SOC 2, HIPAA, and GDPR compliance
- Research-backed LLM evaluation metrics
- Systematic evaluation has a learning curve
- Collaboration and advanced features need the paid cloud
- Team collaboration tools depend on your plan
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
