Ship bulletproof AI voice agents 100x faster with simulation, evaluation and live monitoring.
Automated conversation simulation
Auto-generate test cases from your system prompt or define your own, then run hundreds of parallel simulated conversations with presets for accent, mood and goal.
Rubric-based evaluation
Score every call against weighted, customisable criteria such as task completion, policy accuracy, sentiment, interruption handling and latency, with seven-day trend tracking.
Live production monitoring
Every production call is silently logged and scored in real time, with alerts routed to Slack, email, PagerDuty, Opsgenie, Linear or webhooks when something drifts.
No-code platform integrations
Connect Vapi, Retell or ElevenLabs agents in under five minutes using an API key, or route custom agents through the provided number and API.
Strengths & Pros
+Combines simulation, rubric-based evaluation and live monitoring in one platform.
+Fast native integrations with Vapi, Retell and ElevenLabs using just an API key.
+Rubric weighting and seven-day trend tracking turn voice agent quality into measurable numbers.

Frequently Asked Questions: Relyable vs VS Code
Relyable has 3,451 monthly visits, while VS Code has 7,397,370. Traffic estimates describe audience size, not product quality.
Alert routing to Slack, PagerDuty, Linear and webhooks fits existing on-call workflows.
+Covered by NVIDIA Inception, ElevenLabs Grants and Microsoft for Startups.
Limitations
–Pricing starts at $500/month, so it is a significant commitment for very small teams.
–Native integrations currently center on Vapi, Retell and ElevenLabs; other platforms require the manual prompt-upload and call-routing workaround.
–Evaluation quality still depends on how well you define your rubric and test cases.
–Because it targets production voice agents, it is less relevant if you are only experimenting.
VS Code
Write code with precision, hand bigger jobs to agents, and keep working from anywhere
Agent collaboration and orchestration
Agents open the repository, form a plan, edit multiple files and explain the changes so you can review each diff before accepting it. You can also run several agents in parallel to push a backlog forward.
Model and harness choice
Point the editor at Anthropic, OpenAI, Google, Microsoft or open-weight models, or bring your own key. Pick the Copilot, Claude or Codex harness that matches how you like to work.
Deep language support
JavaScript, TypeScript, HTML and CSS work out of the box, and Marketplace extensions add IntelliSense, linting, refactoring and debuggers for Python, Java, C++, Go, Rust and more.
Full development workflow
Integrated terminal, source control, debugger, testing, Jupyter notebooks, an integrated browser and Dev Containers all live in one window, so you stay close to the code.
Strengths & Pros
+Free, open-source editor with a mature extension ecosystem and years of active development
+AI agents work directly on your real codebase with plans, diffs and reviewable changes
+Freedom to mix models from Anthropic, OpenAI, Google, Microsoft or open-weight providers, and to pick the Copilot, Claude or Codex harness
+One setup covers local development, containers, SSH, WSL, remote tunnels and browser-based editing
+Strong accessibility, enterprise policy and remote-development features for professional teams
Limitations
–AI agent and chat features require a paid GitHub Copilot plan, and heavier agent workflows consume premium request quotas quickly
–The full agent feature set spans VS Code, the Copilot CLI, GitHub Mobile and GitHub.com, which can feel fragmented while the ecosystem matures
–Extensions run with editor privileges, so a poorly maintained or malicious add-on can pose a supply-chain risk
–Large workspaces with many extensions and language servers can get memory-hungry and slow on modest hardware
