Let’s focus on what changed. I’d test a successful purchase, a declined payment, and returning from the background.

More than a place to run your app

The brains behind
the whole workflow.

Cloud devices are the foundation. Bulby AI is the intelligence we’re building on top—connecting your intent to the work, and the work to an answer you can understand.

01

Tell Bulby the goal.

Describe what you want to validate in your own words. Bulby will help turn that conversation into a focused, reviewable plan.

02

Bring the work together.

Coordinate agents and parallel mobile, tablet, and desktop test environments, with a shared understanding of what each run is trying to prove.

03

Understand what happened.

Connect screenshots, recordings, and logs to clear explanations. Ask follow-up questions and decide what to do next.

The platform we’re building

From every code change
to a clearer picture.

We’re building Bulby to bring visual testing, bug investigation, and test management into one connected workflow. Follow each pull request through your app, understand its impact, and see what needs attention.

Visual comparison & screenshot diffing

Compare screenshots across builds to catch unexpected UI changes and see exactly what changed.

Bug discovery & tracking

Find potential bugs, document how to reproduce them, and keep the evidence connected as each issue moves toward resolution.

Usability insights & scoring

Surface friction in the user experience with scores grounded in defined criteria and clear explanations.

Visual user journey mapping

Turn app journeys into step-by-step maps with screenshots, so your team can see the paths users take and where they get stuck.

Pull request impact tracking

Connect test results, visual differences, and reported issues to individual pull requests, making the impact of each change easier to review.

Regression testing

Check critical workflows across builds, phones, tablets, and desktop environments to catch regressions before they reach your users.

Test case management

Keep test cases, coverage, and run history organized as your app evolves, with a clear view of what has been tested and what still needs attention.

AI-guided investigation

Talk through findings with Bulby, inspect the supporting evidence, and get guidance on the next useful check.

Mobile, tablet & desktop testing

Validate your app across phones, tablets, and desktop environments, with coverage tailored to each platform’s layouts and user interactions.

Built to grow with your workflow

Help shape the integrations, automation, and insights that come next. We’re building the roadmap with early-access teams.

Planned capabilities · Scope and availability will evolve during development.

An AI you can work with

An AI that listens.
And makes things clear.

We’re building Bulby to keep context, explain its reasoning, and make space for your judgment. Here’s how that experience could feel.

Illustrative conversation · This preview uses scripted examples, not a live AI.
Trust should be earned

Clear thinking. Visible evidence.
Your final say.

We’re designing Bulby around transparency and human judgment. Every plan and explanation should help you make an informed decision.

Show the work.

Make plans and findings inspectable. Connect explanations to the evidence behind them.

Be clear about uncertainty.

Separate observations from possible causes. Say when more information is needed.

Keep you in control.

Let you review the plan, set boundaries, and approve the next step before work begins.
