RubricHQ vs Cekura
RubricHQ and Cekura both run test calls, score transcripts, and monitor production. Cekura has the longer track record and a self-improving "agent loop" that fixes agents automatically. RubricHQ's edge is a Co-Pilot that answers questions across your call data and an optimizer that learns a prompt rewrite from your good- and bad-call examples.

How they differ
Co-Pilot: querying calls vs running actions
RubricHQ's Co-Pilot answers natural-language questions across every call, transcript, metric, and tag — "which calls had over five seconds of silence and ended with the customer hanging up?" — surfacing patterns you'd otherwise find only by listening through calls by hand. Cekura's Co-Pilot is built to run platform actions, like generating scenarios or starting an eval, that you can also do from its UI.
Prompt optimization
Both close the loop. Cekura's self-improving "agent loop" diagnoses failing scenarios by class, applies prompt or config edits to a clone, and re-validates until the suite passes. RubricHQ diagnoses why a batch failed, learns a targeted prompt rewrite from your good- and bad-call examples, re-runs the same suite to prove the change worked, and can push the new prompt straight to Vapi or Retell.
Compliance and regulated call centers
Cekura carries SOC 2 Type II, HIPAA, and GDPR compliance on its enterprise plans. RubricHQ is newer and still completing those certifications, but tends to go out of its way to meet a customer's specific compliance needs without a large price premium.
Frequently asked questions
Is RubricHQ a good Cekura alternative?+
Yes. RubricHQ covers the same core workflow — test calls, transcript scoring, and production monitoring — and adds a Co-Pilot that queries your call data in natural language plus a prompt-optimization loop that rewrites and redeploys prompts. Cekura is the stronger choice if you need SOC 2 / HIPAA / GDPR compliance certifications in place today.
What was Cekura called before?+
Cekura was formerly named Vocera. It is a Y Combinator F24 company.
Do RubricHQ and Cekura support the same voice platforms?+
Both support Vapi, Retell, LiveKit, and Pipecat. Cekura also lists ElevenLabs and Bland plus telephony and CCaaS integrations (Twilio, Telnyx, SIP/PSTN, Genesys, Kore). RubricHQ adds custom providers on request.
How much does Cekura cost?+
Cekura's self-serve pricing starts at a $500/mo Startup plan, with usage-based charges and enterprise tiers above it. RubricHQ starts free — $0 pay-as-you-go with 200 credits, no card — and Growth is $399/mo, Enterprise custom.
