tldr: TestMu AI (formerly LambdaTest) uses a layered pricing model. Infrastructure and AI are priced separately. Live Testing starts free, with paid plans from $15/month. Kane AI agents cost $199/month per 1,000 agents. Enterprise pricing is custom.

Introduction

TestMu AI rebranded from LambdaTest in January 2026, but its pricing model has stayed mostly the same. The infrastructure layer has not changed in over five years. What is new is the AI layer, built around Kane AI agents.

The pricing structure has two independent parts. You pay for infrastructure (browsers, devices, parallel sessions) and optionally for AI agents (Kane AI). These two layers are billed separately.

How the two layers work

Parallel sessions determine how many tests can run at the same time. More parallels means faster test cycles. This is the same model used by BrowserStack and most cloud testing platforms.

AI agents are the newer addition. Kane AI agents are priced per batch of 1,000 agents. This is not a credit system or usage-based metering. You buy agent capacity and use it however you need.

User seats are treated as an add-on, not a core pricing axis. You can upgrade or downgrade anytime. Changes take effect at the start of the next billing cycle. Annual billing comes with discounts over monthly pricing.

Live testing plans

These plans cover manual browser and device testing in the cloud.

Free plan

  • $0/month, free forever
  • 1 parallel test
  • Access to 3,000+ browsers and OS combinations

Virtual Live

  • $15/month (billed annually)
  • 1 parallel test
  • Virtual machines for cross-browser testing

ChromeOS Live

  • $29/month (billed annually)
  • Real mobile devices included
  • ChromeOS device access for testing on actual hardware

Real Device Plus Live

  • $39/month (billed annually)
  • Full real device access
  • Testing on physical smartphones and tablets

All live testing plans include 24x7 support, localhost and staging testing, network throttling, geolocation testing, and integrations with JIRA, Asana, Slack, and Teams.

Kane AI pricing

The AI layer is where TestMu AI differentiates from the old LambdaTest model.

Kane AI agents cost $199/month per 1,000 AI agents. This is agent-based pricing, not credit-based or usage-based. Whether your agents run simple or complex tasks, the cost stays the same per batch.

This pricing model is separate from infrastructure. You can use Kane AI with any live testing or automation plan. The AI agents handle test generation and execution, while the infrastructure plan provides the browsers and devices to run on.

For teams already paying for TestMu AI features on the infrastructure side, adding Kane AI is an incremental cost on top of existing plans.

What every plan includes

Regardless of which tier you choose, all paid plans come with:

  • 24x7 support
  • Access to 3,000+ browsers and operating systems
  • Localhost, staging, and private website testing
  • Network throttling for simulating slow connections
  • Geolocation testing across regions
  • Integrations with JIRA, Asana, Slack, and Microsoft Teams
  • SOC2-ready security controls

Every paid tier includes these. The free plan includes a subset with limited parallel capacity.

Enterprise pricing

Enterprise plans are custom-quoted. They are designed for large organizations that need more than standard tiers provide.

Enterprise customers get:

  • Dedicated Solutions Engineer
  • Dedicated Customer Success Manager
  • Private Slack channel for support
  • Advanced access controls and permissions
  • Custom data retention policies
  • Volume discounts on both infrastructure and AI layers

If your team has 50+ engineers or compliance requirements like SOC2 or ISO 27001, enterprise pricing is likely the path TestMu AI will steer you toward. Contact their sales team for a quote.

TestMu AI pricing vs BrowserStack

Both platforms use parallel-session-based pricing for infrastructure. The main differences:

  • TestMu AI Live starts at $0 (free forever). BrowserStack Live starts at $29/month.
  • TestMu AI has a separate AI layer (Kane AI at $199/month per 1,000 agents). BrowserStack bundles AI features into certain plan tiers.
  • TestMu AI infrastructure pricing has remained stable for 5+ years. BrowserStack adjusts pricing more frequently.

A different approach to test pricing

TestMu AI charges for the infrastructure to run tests you have already written. Even with Kane AI agents, you are paying for test generation and execution as separate line items.

Bug0 takes a different approach. AI generates and runs the tests. There is no separate infrastructure bill. Bug0 Studio starts at $250/month for self-serve AI testing. Bug0 Managed starts at $2,500/month for done-for-you QA with a Forward-Deployed Engineer pod. For teams without dedicated QA headcount, this bundled model can simplify both the workflow and the budget.

FAQs

Does TestMu AI have a free plan? Yes. The free plan includes 1 parallel test session and access to 3,000+ browsers. It is free forever with no time limit.

How does Kane AI pricing work? Kane AI is priced at $199/month per 1,000 AI agents. It is agent-based, not credit-based. You pay the same whether agents run light or heavy workloads.

Can I use TestMu AI without Kane AI? Yes. The infrastructure and AI layers are independent. You can use live testing or automation plans without adding Kane AI agents.

Is annual billing cheaper than monthly? Yes. All listed prices ($15, $29, $39/month) reflect annual billing. Monthly billing costs more.

What happens when I upgrade or downgrade? Changes take effect at the start of your next billing cycle. There is no proration mid-cycle.

How does TestMu AI pricing compare to LambdaTest pricing? The infrastructure pricing is the same. TestMu AI is the rebranded version of LambdaTest. The main addition is the Kane AI agent layer at $199/month per 1,000 agents.

Does enterprise pricing include everything? Enterprise plans are custom. They typically include dedicated support, advanced access controls, custom data retention, and volume discounts across all products.

How does TestMu AI compare to Bug0 on pricing? TestMu AI charges separately for infrastructure and AI agents. Bug0 bundles test creation, maintenance, and infrastructure into one price starting at $250/month. The right choice depends on whether your team writes its own tests or wants AI to handle that entirely.
