Hardware test for happy engineers

Custom-fit, dedicated testers for each of your PCBAs make testing robust, scalable and reproducible — all for a fraction of the time and cost. With immaculate vibes.

Modern and automated testing - from the lab to the factory floor.

atopile takes the best parts of state-of-the-art software testing tools and hooks them up to your hardware. Batteries included.

Unified Testing: Design to Production

Run the same production-quality tests from early design through qualification and mass production.

Compact & Scalable

Standard 2U rackmount testers allow dense deployment, scaling easily from one benchtop to hundreds of units.

Scale on Demand

Our streamlined, all-on-one-board tester design allows rapid manufacturing. Order dozens or hundreds with short lead times.

Passes (and Fails) to Trust

Eliminate flaky harnesses, janky add-ons and rot. Our integrated design boosts reliability and ensures trustworthy results for long-term use.

An SDK You Already Know

Utilize the power and familiarity of Python, Pytest and OpenHTF. Our testers include drivers and a pytest-based framework, avoiding vendor lock-in.

Data Like You've Never Seen

Seamless integration with data platforms like Zelos ensures test results are easily accessible across your teams.

How it works


We design you an all-on-one-board tester - blazing fast.

Instead of building from physical blocks, we design you single-board tester from our suite of pre-validated circuits, and give you the design alongside your new equipment.

All-in-one testers are robust, reliable and reproducible, with far fewer points of failure (like harnesses). No more flakesIntermittent test failures that waste time and create uncertainty! . A fraction of the maintenance.

Scaling as your team grows is a breeze. Just order more via atopile, or from your vendor of choice. You choose.

All-in-one testers are also extremely compact, typically occupying only 2U rack.

Integrated tester

async def test_current_draw(tester: "Tester"):
    """
    Bleed current performance test.

    cell = tester.cells[0]
    await cell.set_voltage(1)

    # Check the bleed current draw is within spec
    current = await cell.get_current()
    assert 0.02 <= current <= 0.03

Write your first test in minutes. Write as many as you need.

You already know how to write tests. Our drivers are simple, and all include bindings for Python and examples. Our testing framework is only a thin plugin on top of pytest.

Testers are shipped including example tests, so you have a place to start. Batteries included.

Your tests evolve with you - every project, firmware update, and hardware revision builds on your existing test foundation.

Run your testing from anywhere (ideally everywhere).

Anywhere you can run pytest, you can run your tests. Our plugin includes distribution to remote runners, via our ( or yourIf you need a self-hosted or BYO-cloud server, talk to us. ) secure serverTest environments sent to remote runners are ephemeral and destroyed after testing (or when the server is stopped). .

You tests are run the same, whether you hit “Run” in your IDECursor, VSCode, PyCharm, etc. , run pytest from the command line, or from your CI.

Records like a 15th Century Monk. Ease and Access of a 21st Century Data Scientist.

Meticulously record the tester configuration, which specific tester and all the data, from every test, all the time - from the lab to production.

Seamless integration with best-in-class data platforms like Zelos Cloud let you go back and introspect anything you need.

Ship hardware faster.

Prototype-faster, bring-up faster, qualify faster and ship months ahead of schedule.
