Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence. 1 Rating Visit Website Canditech Discover candidates’ real skills - not just their resumes - with Canditech’s candidate evaluation platform.

About Scorable is an AI evaluation and monitoring platform designed to help developers measure, control, and improve the behavior of applications built with large language models. It enables teams to create customized automated evaluators, sometimes referred to as AI “judges”, that assess how an AI system responds to users and whether its outputs meet defined quality standards such as accuracy, relevance, helpfulness, tone, and policy compliance. Developers can describe what they want to measure in plain language, and the platform generates a tailored evaluation stack that tests AI outputs against context-specific criteria rather than generic benchmarks. These evaluators can be embedded directly into application code, allowing AI systems such as chatbots, retrieval-augmented generation (RAG) systems, or autonomous agents to be continuously monitored in production environments.

Pros & Cons from Real Users Pros My team has switched to Opik from Arize about 4 months ago. We have evaluated Arize, Langfuse, Opik and Langsmith. Overall Opik was the best platform. Phoenix OSS doesn't have half the features, Langsmith is nice but super expensive and not OSS and Langfuse is brittle and has tons of performance issues. We found one bug on Opik, opened a PR on the GH repo and it was fixed and merged in less than 5 hours. Cons Personally I think they can make the UI a bit prettier.
