Your current tools are holding you back

Engineers spend more time fighting their tools than analyzing data.

Expensive desktop licenses

€3,000–8,000/year per seat for legacy desktop software. Locked to specific machines. Extra cost for every new engineer.

Zero collaboration

Templates shared by email. Results copied to Excel. No way for two engineers to work on the same analysis simultaneously.

No data sovereignty

Measurement data sits on engineers' laptops or US-hosted cloud services. No control over where sensitive test data lives.

Complete Pipeline

From raw file to report, in one platform

Every operation is a reproducible step. Build pipelines once, replay them on any dataset.

DATA

● Import MDF4, CSV, TDMS
● Channel mapping
● Resample & filter
● Group & merge

PROCESSING

● Clean & align
● Compute derived channels
● Transform & analyze
● Python scripting

EXPORT

● Interactive visualization
● Compare N datasets
● PDF & PPTX reports
● CSV, Parquet export
Channel Reference System (CRS)

Every formula, layout, and workflow uses relative references — not hardcoded file paths. Create a layout once, bind it to any compatible dataset in two clicks.

power_delta = @test:power_kw − @ref:power_kw
Why NeydFlow

Built for how engineers actually work

Not a desktop tool ported to the web. Designed from scratch for modern, collaborative engineering.

01 — WEB-NATIVE

Zero installation

Open your browser, start working. No IT tickets, no license servers, no machine-locked installs. Works on any OS.

02 — PORTABLE REFERENCES

Reusable layouts & formulas

The CRS makes everything portable. A layout created for run #42 works on run #99 without editing. Bind datasets to slots, not filenames.

03 — DEPLOY ANYWHERE

Cloud, self-hosted, or hybrid

SaaS for teams that want simplicity. Docker on your own servers for classified data. Same features, your choice of infrastructure.

04 — REAL COLLABORATION

Share, don't duplicate

Project-level roles (owner, editor, viewer). Shared layouts and workflows. Stop emailing .zip files — work on the same project, together.

05 — REPRODUCIBLE PIPELINES

Traceable from import to export

Every transform is a recorded step. Replay entire pipelines. Export workflows as .nfpkg packages. Full audit trail for regulated industries.

06 — DATA SOVEREIGNTY

Your data, your perimeter

In self-hosted mode, nothing leaves your network. No telemetry, no analytics on your data. European-hosted cloud. GDPR by design.

Feature Spotlight

Compare N datasets
in one click

Select a layout, pick comparison datasets, done. NeydFlow automatically matches channels and overlays traces with distinct styles.

Auto-mapping by channel name, project mapping, or similarity

Toggle individual datasets on/off without reconfiguring

Works with any existing layout — no special setup required

Your Infrastructure, Your Rules

Three ways to deploy

Same features, same interface. Choose where your data lives.

Cloud SaaS

Zero infrastructure to manage. Sign up, start working. Hosted in the EU. Automatic updates and backups.

Best for:
Engineering firms, freelancers, POCs, non-classified data

Self-hosted

Docker containers on your infrastructure. Nothing leaves your network. Air-gappable. Full control.

Best for:
Defense, aerospace, OEMs, classified or regulated data
Coming soon

Hybrid

App in the cloud, data on your servers. A gateway syncs only metadata. Best of both worlds.

Best for:
Tier-1 suppliers needing cloud convenience with data sovereignty
Transparent Pricing

Plans that scale with your team

Full pipeline on every plan. No per-channel fees. No data volume surprises.

Frequently asked questions

NeydFlow natively supports MDF4 (ASAM standard, used across automotive), CSV, and TDMS files. The architecture is extensible — additional formats (HDF5, Parquet, DAT) can be added based on demand. If your team uses a specific format, let us know and we'll prioritize it.

Yes. In cloud mode, your data is hosted in the EU (Germany), encrypted at rest and in transit, with strict tenant isolation. In self-hosted mode, nothing leaves your network — the entire platform runs in Docker containers on your infrastructure. NeydFlow never uses your measurement data for analytics, ML training, or any purpose other than serving you.

NeydFlow reads standard industry formats (MDF4, CSV, TDMS). Your raw data files work as-is — just import them. Layouts and formulas use the CRS, but concepts map directly from existing tools: aliases → NeydFlow slots, macros → NeydFlow Python scripts. We provide migration guides to help you transition smoothly.

NeydFlow is delivered as Docker containers. Your IT team runs docker compose up on any Linux server. Includes PostgreSQL, Redis, MinIO, and the application. Updates are pulled the same way. No installer, no agent, no outbound connection required. Fully air-gappable.

Yes. The Free plan gives you access to the full pipeline — import, process, visualize, compare, export — with 1 project and 5 GB of storage. No credit card required, no time limit. When you need more projects, reports, or collaboration features, upgrade to Pro or Team. Paid plans also offer a 14-day free trial.

Any industry running physical tests: automotive (powertrain, calibration, durability, NVH), aerospace (flight test, engine bench), defense (systems testing), energy (battery testing, turbine monitoring), and rail (vibration, traction). If your engineers work with time-series sensor data, NeydFlow is built for them.
