Infinite Beta Testers Whenever
Stop calling your friends to beta test. Summon actors to use your product before launch, in a low risk, no embarrassment environment.
Made for you
This is for all the real product makers who want to just cut through the cruft and “test” their software by actually “using” it.

Get Started
Sign up and give it a go. Join our Discord so you can tell us how much you love it, or hate it. We're also open to meeting design partners.
No Waitlist
No one likes booking a demo with
the founders just to play with a product. But I also don't mind chatting so here's my calendar.
Easy to use prompt based interface
Write simple user flows instead of rigid unit tests, or complicated QA scripts.
Full user session replays
Replay every “user” experience to observe exactly what they did.
See the rationale behind every action
It’s like if every beta tester actually knew how to give good feedback.
Run multiple flows simultaneously
Run more than one user flow at a time, using multiple “users” at once.
Summon “real” users
Summon realistic “actors” with plausible credentials, which they’ll use to interact with your product.
Product-level bug reports
Be alerted as soon as a “user” encounters anomalies or failure states.
“The best way to test a product is by using it”
– Jacob Bijani, co-founder
We’re changing the way products are built and tested.
Our vision is to build a new approach to testing with this premise at the core. Imagine if your product development cycle had:
- Tighter loops between testing and deployment
- Real product usage before real users
- Discovery of unpredictable use cases and usage patterns
- Reproducible and replayable bug reports
- Really good test data
A few example tasks using our test suite:
Search for something Log in with your credentials Select an item from the dropdown Fill out a complex form Click on each nav linkWho are you?
Synthetic Traffic is created by Jacob Bijani and Allan Yu, proudly funded by Baukunst, Factorial, David Karp, et al.
How Does It Work?
We use a combination of LLMs, CV, and DOM observation to create rationale, session introspection, and actionable steps.
How Much?
So far so free with a usage limit on each account. If you’re hitting it please contact us immediately! Maybe you should be a design partner.
Feature Request
If you’re looking for a specific feature, and we like it, we will add it. That’s how it works right?
What is this for?
We currently work on web based products, especially ones that are impossible to test without actual people using them.
Is this just spam?
No. Our product is designed to interact with your staging or development environment. Don’t use it on sites you don’t control.
How is this different from testing?
Think of us as a wind-tunnel for your product, we help you see what your product feels like under realistic load.
