Quick answer
TestMu AI - TestMu AI wins for most builders because its free tier is perpetual and closer to a usable ongoing plan, while TestingBot is only a 14-day trial unless you qualify for its open-source offer.
How the free tiers compare
These products solve a similar problem, but their free tiers are built for different jobs. TestingBot gives you a short, no-card trial with broad platform coverage and access to real iOS and Android devices, which is useful if you need to validate a stack quickly or test whether the workflow fits your team. TestMu AI is the better long-term free option because the plan is free forever, renews monthly, and includes 60 minutes of live testing plus 1 parallel test. The tradeoff is that its free tier is more explicitly capped, while TestingBot’s trial is broader but expires fast. If you are choosing a free tier to keep using, TestMu AI is usually the safer default. If you need a burst of real-device testing right now, TestingBot can be the better short-term fit.

After you outgrow the free tier
Both products use mostly per-seat pricing after the free tier. TestingBot’s first paid step is Live at $20/month billed annually, then Automated at $50/month and Automated Pro at $90/month, with Enterprise by contact sales. TestMu AI starts lower at $15/month billed annually for Virtual Live, then $29/month for ChromeOS Live and $39/month for Real Device Plus Live, with Enterprise by contact sales. For small teams focused on ongoing live testing, TestMu AI is cheaper at the entry level; TestingBot gets more expensive faster once you move into automated testing.
When to pick each one
Pick TestingBot when…
- You need to try real iOS and Android device testing immediately without entering a credit card.
- You want to evaluate cross-browser automation, visual testing, and live testing in a short pilot window.
- Your project is open source and you want to apply for a free plan.
- You only need a two-week proof of concept to decide whether to buy later.
Pick TestMu AI when…
- You want a free tier that continues month after month.
- You need a small but ongoing allowance for live testing rather than a one-time trial.
- You are fine starting with 1 parallel test and 60 minutes of live testing per month.
- You want a free plan that can support light recurring use while you build.
Bottom line
For the most common builder use case, TestMu AI is the better free-tier pick because it is actually usable over time, not just as a trial. TestingBot’s free offer is valuable if you need a quick no-card evaluation or you qualify as open source, but the 14-day limit makes it a stopgap. If you are choosing what to live with while staying free, TestMu AI is the more practical default. If your immediate need is a short burst of broader device testing, TestingBot can still be the sharper tool.
