RubricHQ vs Bluejay
There are two ways to fix a voice agent’s prompt: let the platform do it, or review every change yourself. Bluejay and RubricHQ both simulate callers, score calls, watch live traffic and fix prompts, but they take different approaches. Bluejay can run the fix loop on its own against a simulation. RubricHQ shows where conversations break, which mistakes repeat and the exact change, and you approve every edit before it goes live.
- Both do
- Simulated callers, production scoring, alerts, scheduled runs, CI/CD, grouped production failures, and Vapi, Retell, LiveKit and Pipecat connections
- RubricHQ adds
- Flow (stage-by-stage call paths), Opportunities (recurring mistakes with the prompt change attached), a Prompt Optimizer you approve with a word-level diff, Co-Pilot (plain-English questions across every call, with CSV export), and poor network simulation
- Bluejay is known for
- Automatic prompt fixing with Self-Improve, red teaming on every plan, uptime monitoring, a wide integration list, and SOC 2 Type II on every plan

What Bluejay is — Bluejay is a testing and monitoring platform for voice and chat agents, known for automatic prompt fixing with Self-Improve, red teaming, uptime monitoring, a wide integration list, and SOC 2 Type II on every plan.
The scorecard
● has it ● limited ● no| Capability | RubricHQ | Bluejay |
|---|---|---|
| Call drop-off points | Flow maps conversations stage by stage, in production and simulation | Production issues grouped by failure mode; logs, traces and dashboards; no stage-level funnel listed in its docs |
| Recurring mistakes | Opportunities groups repeat failures with evidence calls and a suggested prompt change | Issues group production failures with counts and priority; investigate with Bluejay AI or copy a fix prompt |
| Fixing the prompt | You pick the calls, review the gaps and a word-level diff, approve, and can roll back | Self-Improve runs automatically against a simulation and keeps a fix only if the pass rate rises; kept prompts are saved as versions you can roll back |
| Asking questions of your calls | Co-Pilot: plain-English questions, table results, CSV export | Bluejay AI: asks why calls fail; also creates tests, metrics and dashboards |
| Production monitoring | Live calls with pass or fail, end reason and latency | Every production call evaluated; dashboards; uptime and heartbeat checks |
| Simulated callers | Phone, web and text; 65+ languages; accents and moods | Voice, chat, SMS, email and IVR/DTMF; 70+ languages and dialects; 24+ accents |
| CI/CD | GitHub Action blocks a deploy when the pass rate drops below your threshold; API for other CI | CI/CD integration that fails a build when the score drops; GitHub Actions and GitLab CI |
| Alerts | Scheduled metric checks that alert your team’s channel | Threshold alerts to Slack, email, webhook, PagerDuty, Better Stack and incident.io |
| Integrations | Vapi, Retell, LiveKit, Pipecat and more | Vapi, Retell, LiveKit, Pipecat, ElevenLabs, Bland, Kore.ai, Dialogflow CX, SIP and PSTN |
| Compliance | Data residency and self-hosting on Enterprise; SOC 2 and HIPAA in progress | SOC 2 Type II on every plan; signed BAA and DPA from Growth; SSO and SCIM on Enterprise; self-hosted or on-prem deployment offered |
| Pricing | $0 trial (200 credits, valid 14 days); Growth $399 per month for 12,000 credits and up to 50 seats | $0 plus usage with $25 in free credits; Growth $500 (about 1,500 simulation and 13,000 monitoring minutes); Scale $1,000; Enterprise custom; unlimited seats on every plan |
How they differ
What a dashboard can’t tell you, and what to do about it
Dashboards are good at showing that a number moved. They’re weaker at showing why. Here are four places where that gap costs teams time.
Flow: where do calls drop off?
Bluejay groups production failures into issues, with logs, traces and dashboards behind them. RubricHQ’s Flow adds the shape of the conversation. You define stages, for example Greeting → Authentication → Balance Notification → Payment Option Selection, and Flow shows how many calls move between them and where they fall out. Toggle between production and simulation to compare what you tested with what really happened.
It also writes out the biggest divergence in plain language, separating ideal paths (outcomes that pass at least 80% of the time) from problem paths. Click a stage or a band to read the calls behind it, filtered to all, passed or failed.
Opportunities: which mistakes keep repeating?
Bluejay’s Issues match each production failure to similar ones from your other conversations, with a priority, a status and a conversation count. From there you investigate with its AI assistant or copy a fix prompt. That tells you which problems are most common.
RubricHQ puts the answer on the card itself: stage, severity, a 30-day count, evidence calls, a “what goes wrong” explanation and a “what the agent should do” recommendation. Each card moves through Open, Fix suggested, Fix applied or Dismissed, so nobody on the team wonders what’s still outstanding.
Prompt Optimizer: what should the prompt say instead?
Bluejay’s Self-Improve is automatic. It generates metrics, runs your simulation, diagnoses one failure pattern, rewrites the prompt and keeps the change only if the pass rate goes up. To do this it pushes each test prompt to the live agent on its platform, so it should run on an agent you use for testing. You confirm a preview before the run starts, and a prompt that beats the baseline is saved as a new agent version you can roll back to.
RubricHQ works the other way. You select up to five calls, and the optimizer lists the gaps it sees, each linked to a failing metric and the calls that show it. You edit, delete or add gaps before it writes anything. It then drafts a rewrite for your model with a word-level diff.
Approving the change updates your RubricHQ test agent. A second step pushes the same prompt to your live agent in Vapi or Retell. Every optimization is versioned and can be rolled back.
Co-Pilot: questions in plain English
Type “how many calls ended with only a partial payment?” or “which callers needed more than one attempt to verify identity?” Choose a time range and a source (production, test runs, or both) and get a table with call, time, duration and outcome, exportable to CSV.
Simulation and metrics
Give RubricHQ your prompt and it generates the scenarios. They run as real calls through Vapi, Retell, LiveKit or Pipecat on every plan. Personas vary by mood, accent and 65+ languages.
Metrics come in system, agent and global sets, with LLM-as-judge and code-as-judge options, and an AI generator can draft new ones. You switch each metric on or off per agent.
Pricing: start free

Frequently asked questions
Is RubricHQ a good Bluejay alternative?+
Yes, if you want to review each prompt change yourself and see where in the conversation calls break. It covers simulation, evaluation and monitoring, then adds Flow, Opportunities, a reviewed Prompt Optimizer and Co-Pilot. If you need SMS and email testing, IVR and DTMF flows, red teaming, uptime checks or a completed SOC 2 Type II report today, Bluejay is built for those.
Do both work with Vapi and Retell?+
Yes. Both connect to Vapi, Retell, LiveKit and Pipecat. Bluejay also lists ElevenLabs, Bland, Kore.ai, Dialogflow CX and others.
What does Bluejay cost?+
Pay as you go is $0 plus usage, with $25 in free credits. Growth is $500 a month and Scale is $1,000. RubricHQ’s Growth plan is $399 a month, and you can start at $0 with 200 free credits and no card.
