Bluejay
Bluejay tests, monitors, and improves voice and chat AI agents with Digital Human simulations and production observability.
If voice agents answer your customers, Bluejay is the most complete test-and-observe stack we've reviewed this year. The September 2026 agent-versions API, August Issues triage, and audio-level custom metrics are shipped engineering, not roadmap copy — and you can trial it on $0/mo plus $25 in credits. Growth at $500/mo is the real decision point: that's where signed BAA/DPA, 100 concurrent simulations, and 30-day retention begin.

Skip Bluejay if you want an agent builder rather than a test layer, if your stack is text-only with no voice roadmap, or if you need SSO/SAML without moving to Enterprise pricing.
Simulations and production monitoring draw from the same credit pool, so a heavy testing month eats the monitoring minutes you budgeted.
Pay-as-you-go at $0/mo plus usage (with $25 in free credits) is the cheapest credible on-ramp in the voice-agent eval category and enough for a solo builder or a first proof of concept. Teams shipping to production typically land on Growth at $500/mo, which is where signed BAA/DPA, 100 concurrent simulations, and 30-day retention begin. Scale at $1,000/mo targets high-volume shops needing 200 concurrent simulations and 90-day retention. Enterprise is custom for redlined terms, SSO/SAML with

What's new in Bluejay
Checked 6 days agoAcross the latest 5 updates: 4 feature updates and 1 news mention.
Adaptive Red Teaming for Conversational AI
Bluejay published guidance on adaptive red teaming for conversational AI, covering automated adversarial testing of voice agents rather than fixed edge-case checklists.
Agent versions in the API
Agent versions now live at /v1/agents/{id}/versions with create, list, get, delete, promote, and label endpoints; prompt_id on simulations is deprecated and an unknown version falls back to production with a warning.
Better Stack paging for alerts and uptime monitors
Alerts and uptime monitors can page through Better Stack alongside PagerDuty. Paste an Uptime API token, switch on Better Stack Notifications, and DOWN opens an incident while recovery resolves it.
Issues: grouped production failure triage in Monitor
Production failures group into titled Issues once the same problem recurs across calls, with known errors surfacing on recognition. The list is grouped by status and unpaginated.
Digital Humans add nine languages plus dialect-aware prompting
Digital Humans added Urdu, Hebrew, Tagalog, Telugu, Tamil, Malayalam, Kannada, Marathi, and Gujarati, plus Egyptian and Levantine Arabic native dialect voices, with dialect-aware prompting on every non-English language.

About Bluejay
Bluejay is a QA and observability platform for teams whose voice and chat AI agents talk to real customers. You point lifelike Digital Humans at your agent's workflows, replay production calls to reproduce failures, and load test concurrent simulations to surface latency and capacity problems before they hit a live support line. The platform splits into three jobs sharing one credit pool: Test, Monitor, and Improve. Test covers voice, chat, and text simulations with automated test generation, tool-call testing, regression runs, scheduled and CI/CD runs, and red teaming (Bluejay published guidance on adaptive red teaming for conversational AI in October 2026). Monitor brings production conversation tracking, tool-call tracking with OpenTelemetry traces, dashboards, threshold alerts, and uptime checks; August 2026 added Better Stack paging beside PagerDuty, and Issues groups recurring production failures into triageable patterns. Improve is where Bluejay separates from pure eval tools — the same platform that scores your agent also feeds fixes back into it. Digital Humans now speak nine additional languages, from Urdu and Tagalog to Tamil and Gujarati, plus Egyptian and Levantine Arabic dialect voices with dialect-aware prompting. Every run is scored against a 70+ metric library plus unlimited custom metrics, including audio-judged custom metrics and outbound call-outcome checks like voicemail detection or abrupt termination. Public proof points are named: Google reports 648 hours a month saved through automated testing, and Casper Studios credits Bluejay in the Netflix x Doritos Stranger Things voice launch at 400k calls with zero bugs. Pricing is self-serve — $0/mo pay-as-you-go with $25 in credits, Growth at $500/mo, Scale at $1,000/mo, Enterprise custom. Against general-purpose eval tools like LangSmith or Braintrust, the differentiator is native voice simulation and production call replay rather than a generic trace viewer.
Behind the Verdict
Pick Bluejay when a bad call costs you money. Order-taking phone trees, drive-thru lines, returns desks, appointment scheduling — anything where a dropped transfer or an ignored disclosure is a real loss. The load-testing angle matters more than vendors admit: 200 concurrent simulations on Scale is how you find out your agent falls over at peak before your customers do. The reason we'd shortlist it over LangSmith or Braintrust is the voice path. Those tools will happily score a text transcript; Bluejay runs an actual lifelike caller with a dialect, listens to the audio, and judges custom metrics on the audio itself. That's a different test, and for a telephone workflow it's the one that catches problems. The September 2026 agent-versions API deserves a look if you already have CI. Versions live under /v1/agents/{id}/versions with promote and label endpoints, so you can pin a regression suite to a specific agent version instead of chasing whatever is in production. Note the migration detail — prompt_id on simulations is deprecated, and an unknown version silently falls back to production with a warning. Wire that fallback into your pipeline's fail conditions or a typo will quietly test the wrong thing. Where it bites: the free tier is a trial, not a home. Credits burn, and concurrency caps at 25 until you pay. Solo developers and text-only chatbot teams will find better value in a lighter eval tool — you're paying for voice machinery you won't use. SSO/SAML with SCIM is Enterprise-only, which is an awkward conversation if your security team requires it at a startup budget. In practice, the teams that get the most out of it run Bluejay alongside their own observability. The OpenTelemetry traces are useful precisely because they don't trap you — you keep your existing

Real-world workflow fit
Concrete scenarios for the personas Bluejay actually fits — and what changes day-one when you adopt it.
Connect the production agent through the Twilio integration, generate test scenarios and personas automatically, and run a scheduled regression suite in CI/CD before each deploy.
Outcome: Regressions in disclosure wording and tool calls are caught in staging instead of on a live support line, and the run history gives an audit trail per agent version.
Move to the $500/mo Growth tier for signed BAA and DPA, then build deterministic required-disclosure metrics by typing the exact phrases the agent must say and run 100 concurrent simulations before go-live.
Outcome: Compliance checks are deterministic rather than LLM-judged where they need to be, and concurrency headroom covers peak-traffic simulation without a sales conversation.
Ingest production calls into observability, watch OpenTelemetry tool-call traces and threshold alerts, and let Monitor → Issues group recurring failures into titled, status-tracked patterns.
Outcome: A recurring tool 500 or a call that should have transferred surfaces as a named Issue instead of a scatter of individual bad calls, and Better Stack or PagerDuty pages on the alert.
Use Cases
- Simulate thousands of customer service calls to validate agent behavior before deployment.
- Replay production calls to debug failures and improve agent responses.
- A/B test different prompts and flows to optimize conversion rates.
- Automatically evaluate agent compliance with healthcare or financial regulations.
- Load test your voice AI agent under peak traffic to ensure low latency.
- Catch regressions in multi-turn conversations after prompt updates.
- Red-team your voice agent with adaptive adversarial testing to uncover security edge cases.
- Use custom SIP headers to test agents behind custom-routing infrastructure.
Limitations
- Bluejay is a testing and observability platform, not an agent builder — you bring an existing voice or chat agent and connect it via native integrations, SIP, or API.
- Pricing is usage-based: simulations and production monitoring draw from the same credit pool, so heavy testing and heavy monitoring compete for the same credits.
- Credit burn is tier-dependent and overage credits burn faster on lower tiers (1.8x on Growth, 1.5x on Scale), while Pay-as-you-go carries no overage.
- Data retention is tiered at 14 days on Pay-as-you-go, 30 on Growth, and 90 on Scale, with custom retention only at Enterprise.
- SSO/SAML with SCIM provisioning and a custom uptime SLA are Enterprise-only.
- Signed BAA and DPA start at Growth.
- No on-premise deployment option is published.

Where the pricing makes sense
The company stage and team size where Bluejay's pricing actually pencils out — and where peers do it cheaper.
Pay-as-you-go at $0/mo plus usage (with $25 in free credits) is the cheapest credible on-ramp in the voice-agent eval category and enough for a solo builder or a first proof of concept. Teams shipping to production typically land on Growth at $500/mo, which is where signed BAA/DPA, 100 concurrent simulations, and 30-day retention begin. Scale at $1,000/mo targets high-volume shops needing 200 concurrent simulations and 90-day retention. Enterprise is custom for redlined terms, SSO/SAML with
Setup time & first value
How long it actually takes to get something useful out of Bluejay — broken out by persona, not the marketing-page minute.
Pay-as-you-go is self-serve with $25 in free credits, so a builder with an existing agent endpoint can get a first simulation running the same day — minutes if the agent is already on a supported provider like Vapi, Retell, Bland, or Pipecat. Growth adds an onboarding call and a Slack support channel; Scale adds weekly success calls; Enterprise adds white-glove onboarding and a dedicated
Switching to or from Bluejay
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ad-hoc internal test scripts: connect your agent via a native provider integration, SIP, or API and port your existing cases into automated test generation plus the 70+ metric library.
- →From a text-first eval tool: point it at Bluejay's voice simulations to pick up audio-level custom metrics and outbound call-outcome checks your transcript-only setup can't score.
- →From manual QA listening to call recordings: ingest production calls into observability so Issues grouping and threshold alerts replace the listening queue.
- →From a single-provider built-in tester: add the remaining providers from Bluejay's integration list so multi-vendor agents share one test and metric definition.
- ↗To a general-purpose LLM eval platform: export simulation results and custom metric definitions, accepting loss of native voice simulation and production call replay.
- ↗To your agent provider's built-in testing: keep only the cases that port, accepting loss of concurrent load testing and the cross-provider metric library.
- ↗To a self-hosted test harness: rebuild Digital Humans, the metric library, and CI/CD wiring in-house, which is the exact build Bluejay replaced for teams like Google and Cloudtech.
