Products

One platform. Three specialist modules.

Every module is native to Fluidraft — same objects, same solver, same canvas — and independently licensed: buy any combination. Where two modules are present they compose: manufacturing limits constrain the generative search, droplet targets become search objectives.

FLUIDRAFT

Core platform

Microfluidic CAD with a physically validated hydraulic solver: parametric channels, valves and junctions, real flow rates and pressures on click, fab-ready GDSII / STEP export.

FABRIX

Module 001 · Manufacturing & DFM

Can this chip be made with the process you chose? Object-level DFM findings, a deterministic readiness grade with its logic on screen, tolerance-to-flow studies, a one-zip package for the shop.

ASSAYFORGE

Module 002 · Generative Design

State the target, allow-list what may change, set hard constraints — get ranked candidates, every one verified by the deterministic solver, accepted only by your explicit, undoable hand.

DROPLET LAB

Module 003 · Droplet Microfluidics

Regime, droplet size and frequency from cited, validated models that state their domain — and refuse to answer outside it. Operating maps, robustness, and a straight line to your fab's limits.

Design. Simulate. Verify. Export.

One tool for the whole loop between an idea and a mask file — with the physics attached to the geometry, not living in a spreadsheet next to it.

Design

Parametric microfluidic CAD

22 components — channels, serpentines, junctions, membrane valves, manifolds, droplet T-junctions, chip-to-world fittings — with magnetic port snapping and interactive channel routing. Geometry regenerates deterministically from parameters, on an integer-nanometer grid.

Simulate

A solver you can check

Steady-state 0D/1D hydraulic network solve with exact rectangular-duct resistance and process-true cross-sections. Pressure, flow, velocity and Reynolds overlays; live flow playback at true branch velocities. Every assert in the validation suite is against closed-form hydraulics.

Verify

The Lab

Monte Carlo over your fab's real tolerances with an error budget; species transport for gradient designs; RC transients for valve switching; and calibration that fits the model to measured operating points from your actual chip.

Export

Fab-ready outputs

GDSII with a 1 nm database unit (KLayout-ready), DXF, SVG, CSV, a fabrication-readiness report with design hashes, true-scale STL, true B-Rep STEP (OpenCascade kernel, process-true cross-sections) and an OpenFOAM case scaffold for the day you need field CFD.

An engineering viewport

Three render styles, orthographic and perspective cameras, section planes, measuring and dimensioning, layer explode, PNG snapshots — and a one-click MP4 recording of your simulation with the telemetry burned in, ready for a group meeting.

Optional AI

Ask Pip

A design assistant that reads your project and its solved physics, and may only propose changes — you apply them. Metered per licence, server-side. No API keys ever ship in the product, and everything else works with the AI off.

One subscription. Every seat works offline.

Fluidraft is sold the way professional CAD is sold: subscribe, download, and run it on your own machine. Pay monthly, or pay for the year in one go and get two months free. Your licence is a signed file — it works behind lab firewalls and never phones home during its term.

Academic — 50% off everything

Degree-granting institutions pay half, verified by institutional e-mail: Core $39/mo · $390/yr, each module $24/mo · $240/yr, Full Suite $94/mo · $940/yr. For research and teaching — commercial services need a standard licence. Write from your institutional address to fluidraft@aliantico.com.

How buying works. Checkout is online and secure (Stripe); after payment your signed licence file (.fldlic) arrives by e-mail from fluidraft@aliantico.com — usually within a few hours, always within one business day. Install it from the licence chip inside the app; activation is fully offline. Prefer an invoice first? Just write to us. Full terms: the End User Licence Agreement.

The honest terms, in plain words. While your subscription runs, everything works, fully, offline. If it ends, Fluidraft switches to the free watermarked evaluation mode: every project still opens, nothing is deleted, and everything you already exported stays valid — your data is never held hostage. Renewing restores full access instantly, offline, with a new licence file. And before you pay a cent, the evaluation mode is the complete product with a watermark on exports — take as long as you need.

No countdowns, no invented scarcity, no fake reviews. Fluidraft launched in 2026 and has no testimonials yet — we won't write our own. Founding prices rise only against shipped capabilities, never against a calendar, and never for renewing subscribers.

Where the edges are

Fluidraft is scoped on purpose — we'd rather you find the edges here than after buying. The full list is a page of its own: what Fluidraft doesn't do.

It is not field CFD. The solver is network hydraulics — steady-state plus a distributed 1D transient model (pressure propagation along channels), validated against closed-form solutions. It will not simulate turbulence or two-phase break-up: droplet outputs are labeled correlations, and when a design truly needs CFD, Fluidraft exports a ready-to-mesh OpenFOAM case instead of pretending.

It is not a freeform CAD modeler. The 3D view is a true-to-fabrication 2.5D engineering visualization; it exports STL and — on a real OpenCascade B-Rep kernel — true STEP solids with process-true cross-sections. What it doesn't do is freeform solid sculpting: editing stays 2D-parametric, because planar microfluidics is 2D with depth.

It does not validate your chip for you. Manufacturability rules are indicative, and results become a validated digital twin only after you calibrate against measurements from a fabricated device — the Calibration tab exists precisely for that. Fluidraft makes no regulatory-compliance claims of any kind.

Requirements — including the honest ones

Browser demo: Any modern browser. Nothing to install, nothing uploaded. This is the full UI with the solver running client-side.
Full product: Windows, macOS or Linux with Python 3.11+ (a two-minute install: virtual environment, pip, one command to serve), or Docker. Any modern browser as the interface. No GPU required — the 3D view auto-degrades gracefully on software rendering.
Known limitations, published on purpose: There is no packaged one-click installer yet — the product currently runs from source or Docker, which suits its early technical audience; signed installers are on the roadmap. Local single-user by design: no cloud sync, no multi-user accounts. The browser demo runs a reduced rule-check engine; the Python core is canonical.
Internet: Not required — except for the optional AI assistant.

Know your chip's flow before you pay to fabricate it.
