Is TestFlow a LabVIEW replacement?

Yes, for most hardware validation tasks. TestFlow offers a modern, code-optional approach that replaces complex LabVIEW VIs with intuitive, reusable workflows, while still allowing Python scripting for advanced needs.

Can I migrate existing workflows?

Yes. While we don't import .vi files directly, our AI can help map your test logic into TestFlow workflows quickly. We find that rebuilding in TestFlow often clarifies and simplifies legacy logic.

What hardware is supported?

We support standard bench instruments (Oscilloscopes, Power Supplies, DMMs, etc.) via SCPI over USB, Ethernet, GPIB, and Serial. We handle the driver complexity for you.

No. TestFlow comes with built-in drivers for a vast range of common instruments. You just connect them, and we handle the communication protocols.

Is it open / scriptable?

Absolutely. You can drop into Python at any point in a workflow to write custom logic, analysis, or specific control sequences using standard libraries.

Why switch

Why teams move
away from LabVIEW

The license bill is only the visible part. The real cost shows up in the four places every validation team feels weekly.

Setup time

Weeks spent on environments, drivers, and dependencies instead of testing.

Code reuse

VIs are hard to share, diff, or reuse across test benches and teams.

Scaling

Performance bottlenecks as tests grow complex and data volume climbs.

Reporting

Manual data extraction and report building slows every decision down.

How switching works

From LabVIEW project
to running workflow

You do not port VIs. You map the test intent directly into TestFlow and let the agent rebuild the automation, which is why the first workflow takes minutes, not a migration project.

Who it is for

Built for the teams
driving hardware forward

If your week involves a bench, an instrument, and a deadline, TestFlow was built for you.

Validation engineers

Automate complex measurements, control instruments from the browser, and generate audit-ready reports in seconds instead of compiling them by hand.

Lab teams

Collaborate on test flows, share instrument setups, and standardize validation procedures across the lab. One source of truth instead of scattered VIs.

Post-silicon / system validation

Accelerate bring-up and characterization with reusable automation that scales from the first board on the bench to production test.
