Roark
Pre-launch simulation and post-call scoring for voice AI agents.
Roark is the most complete testing and observability platform we've seen for voice agents. The simulation-to-production loop is genuinely useful, and audio-native metrics catch failures that transcript-only tools miss. If you run a serious voice agent, the pay-as-you-go entry with $50 credit is a low-risk way to see it work, but budget for the $500/mo Team plan once you scale past a few thousand minutes.

Skip Roark if you're building chat-only agents (audio features won't matter), or if your voice traffic is under ~500 minutes/month and you can't justify $500/mo for the Team plan.
Going past 10k monthly API calls adds $0.002 per extra call, which adds up fast at high volume
Roark's usage-based pricing suits teams that already run voice agents and need QA. With $50 free credit, you can test it with low risk. Once usage exceeds ~$500/mo, the Team plan at $500/mo provides a better rate. For large volumes (>40k sim minutes), Enterprise's committed $0.05/min rate wins. Competitors like [Alternative] may offer flat tiers, but Roark's per-minute model aligns cost with usage.

About Roark
Roark is a testing and observability platform built specifically for teams shipping customer-facing voice AI agents on Vapi, Retell, LiveKit, Pipecat, or your own stack. It closes the loop between catching a failure in production, proving a fix in simulation, and shipping with evidence. Before launch, you can run your agent against hundreds of realistic simulated callers—angry customers, ramblers, interrupters, red-teamers, and code-switchers—across 45 languages with background noise and edge cases. After launch, every production call is scored automatically on 64+ audio-native metrics, including pronunciation, accent clarity, vocal stress, empathy, task success, compliance (disclosures, PII exposure, identity checks), and latency. Roark uses purpose-built audio models on the waveform, not just LLM transcript analysis, so it measures what the caller actually heard. It also supports load testing, regression testing, CI/CD quality gates, issue tracking, alerts, OTEL traces, human review, and a prompt optimizer that drafts fixes from failing calls. Roark is SOC 2 Type II and HIPAA BAA compliant, and offers usage-based pricing with a free tier and no card required.
Behind the Verdict
Roark stands out because it measures audio itself, not just transcripts. This matters for pronunciation, vocal stress, and dead air—failures that an LLM grading a transcript would miss. The platform is comprehensive: from pre-launch simulation (scenarios, red teaming, 45 languages, load testing) to post-call scoring (64+ metrics, issue filing, alerts) to the self-improvement loop (prompt optimizer, suggested fixes). For teams building voice agents on Vapi, Retell, LiveKit, or Pipecat, Roark integrates seamlessly and adds the QA layer that's otherwise missing. It's particularly strong for regulated industries (healthcare, finance) where compliance scoring on every call is essential. The pricing is fair but adds up. Pay-as-you-go at $0.15/min simulation and $0.04/metric/min is fine for trials, but the Team plan at $500/mo is a jump. Enterprise is $4k/mo+. For low-volume teams, a $50 credit won't last long, and there's no cheap subscription tier. One limitation: Roark is not a voice agent builder. You still need Vapi or similar. Also, while it supports 45 languages, audio-native metrics like pronunciation may work better in some languages than others. Overall, if you're serious about voice agents, Roark is the gold standard for QA. The blog updates reflect a rapidly evolving field, and Roark is staying ahead of issues like model swaps, code-switching, and outbound calling.

Real-world workflow fit
Concrete scenarios for the personas Roark actually fits — and what changes day-one when you adopt it.
Before a deploy, run a simulation suite with angry caller personas and red team attempts.
Outcome: Identify failures (e.g., agent gives refund without identity check) and fix them before production.
After launch, set up dashboards to monitor compliance metrics and issue alerts on threshold breaches.
Outcome: See live scores for disclosures, identity checks, and empathy; receive Slack alerts when a metric dips.
Integrate Roark with CI/CD pipeline to run regression tests on every prompt change.
Outcome: Catch regressions before merge; use OTEL traces to debug slow turns.
Use Cases
- Test a new voice agent flow by simulating angry customer personas with background noise.
- Monitor live calls for compliance deviations and trigger Slack alerts on failures.
- Auto-generate regression tests from 37 failed production calls in one click.
- Compare success rates across agent variants using graph-based conversation flows.
- Analyze multi-speaker conference calls (up to 15 speakers) for talk time distribution.
- Set up dashboards and scheduled reports to track latency and repetition metrics over time.
- Run a full test suite in CI before every prompt or model merge.
- Verify that AI disclosure statements are correctly delivered as state laws vary.

Where the pricing makes sense
The company stage and team size where Roark's pricing actually pencils out — and where peers do it cheaper.
Roark's usage-based pricing suits teams that already run voice agents and need QA. With $50 free credit, you can test it with low risk. Once usage exceeds ~$500/mo, the Team plan at $500/mo provides a better rate. For large volumes (>40k sim minutes), Enterprise's committed $0.05/min rate wins. Competitors like [Alternative] may offer flat tiers, but Roark's per-minute model aligns cost with usage.
Setup time & first value
How long it actually takes to get something useful out of Roark — broken out by persona, not the marketing-page minute.
With $50 credit, you can start simulating within minutes—connect your agent via SDK or API, pick a persona, run a suite. For CI/CD integration, expect a few hours to set up CLI or REST API. For full adoption (alerts, dashboards, human review), plan a day or two.
Switching to or from Roark
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual testing: Replace spreadsheets with automated simulation suites and quantitative metrics.
- →From transcript-only QA: Add audio-native metrics to catch pronunciation and tone issues.
- ↗To a custom evaluator: Export OTEL traces and call data to build in-house metrics.

Featured Head-to-Head Comparisons
Roark vs Locus Robotics
These tools serve completely different domains: Locus Robotics automates physical warehouse tasks with AMRs, while Roark ensures the quality of voice AI agents. Choose Locus if you're scaling eCommerce fulfillment and need flexible, robot-assisted picking; choose Roark if you're building or deploying voice AI agents and need rigorous testing and observability. There's no overlap in function or buyer.
Roark vs Truleo
Truleo and Roark are not competitors—they serve completely different buyers. Truleo is for law enforcement agencies needing to surface leads from jail calls, body cameras, and RMS, while Roark is for voice AI teams needing to test and monitor their conversational agents. Choose based on your domain: police work or voice agent development.
Roark vs Presto Voice
Choose Presto Voice if you run a multi-location QSR drive-thru and need a proven voice AI that automates orders and boosts revenue via upselling — it's built for restaurant operations, not engineering. Choose Roark if you're a voice AI development team shipping agents and need rigorous QA and monitoring across the full lifecycle, from simulated testing to live call observability. They solve entirely different problems — Presto is operational, Roark is technical.
