- LLM evaluation and optimization
Temperstack
AI-driven reliability platform that automates monitoring, alerting, and incident management across observability stacks.
Temperstack is a reliability engineering platform that uses AI to unify monitoring, alerting, and incident response across the tools teams already use. Instead of replacing existing observability stacks, it layers on top of them to detect gaps in coverage, generate meaningful alerts, and streamline how on-call teams respond to issues. The platform helps SRE and DevOps teams reduce alert fatigue, shorten mean time to resolution, and maintain consistent reliability standards across services. By automating routine tasks like alert configuration, runbook execution, and post-incident analysis, Temperstack frees engineers to focus on higher-value reliability work.
Criteria breakdown
- AI-assisted alert configuration
- Cross-tool incident management
- Automated monitoring audits
- Runbook automation
- Post-incident reporting and analysis
- Integrations with major observability platforms
AgentOps is a developer platform focused on the lifecycle of AI agents, providing tracing, monitoring, and debugging tools that surface what agents actually do at runtime. It captures LLM calls, tool usage, costs, and errors so teams can understand agent behavior across complex multi-step workflows. Beyond visibility, AgentOps offers session replay, performance analytics, and integrations with popular agent frameworks like LangChain, CrewAI, and AutoGen. This helps engineers move from prototype to production with measurable reliability instead of relying on guesswork or log scraping. It is aimed at developers and teams shipping agentic applications who need to track regressions, control spend, and prove that their agents behave correctly before and after deployment.
Criteria breakdown
- Agent session recording and replay
- LLM call and tool-use tracing
- Cost and token analytics
- Error and failure detection
- Framework SDKs for Python and JavaScript
- Dashboards for agent performance metrics
