| Description | SMSVAR provides disposable virtual phone numbers for receiving SMS verification codes across 1,600+ platforms and 190+ countries. Users pick a country and service, pay the quoted price, and receive the code within seconds through the web dashboard or a Telegram bot; numbers can also be rented hourly, daily, or weekly for repeat use on the same number. It's aimed at marketers managing multiple platform accounts, QA teams needing bulk account creation, and privacy-conscious users who don't want to share a personal number -- its main differentiator is an automatic balance refund if a code doesn't arrive within 20 minutes, plus a tiered cashback bonus on top-ups. | LangWatch is an open-source, framework-agnostic platform for testing, evaluating, observing, and optimizing AI agents and LLM applications. It uses simulation-based testing with real-user text and voice conversations, LLM-as-a-judge evaluations, red teaming, and OpenTelemetry-native observability to catch issues and prevent regressions. It supports collaboration between technical and non-technical teams and can be deployed as cloud, self-hosted, or hybrid. |
