Tractrix Cloud
The OpenAirside engine as a shared service for your team. Bring a drawing, run the manoeuvre, keep every run with its parameters and results, and hand the same API to your CAD add-ins and scripts.

What it does
A workspace for airside studies.
Cloud runs exactly the engine that powers Tractrix for QGIS, AutoCAD and Revit. What it adds is organisation: who can see a study, what was run, with which inputs, and when.
Data
Projects and drawings
Group work by airport and study. Upload GeoJSON or DXF; arcs, bulges and splines are flattened to about 2 cm chords, and units are read from the DXF header.
Analysis
Runs you can reproduce
Each run stores its tractrix/1 request, engine version, summary, notes and result layers, so a result can be re-opened or re-run later.
Output
Exports for every tool chain
Download result layers as GeoJSON or DXF, the summary as CSV, or a self-contained HTML report for the study file.
Automation
API tokens
Organisation-scoped tokens (prefix tx_) for the CAD add-ins, CI pipelines and scripts. Tokens are stored hashed and can expire or be revoked.
Security
Accountable by design
Short-lived access tokens with rotating refresh cookies, e-mail verification, rate-limited sign-in, and an organisation audit log for admins.
Preview limits
Know the envelope before you run.
These are the limits configured for the preview service. They protect a shared service and may change before general availability; plan limits are on the pricing page.

| Simulation request size | 4 MB |
| Points per path | 20 000 |
| Aircraft or vehicles per request | 12 |
| Simulation time-out | 30 s |
| Access token lifetime | 15 min |
| Invitation validity | 14 days |
Early access
Join the preview.
Tractrix Cloud is being evaluated with a small number of airport planning teams before it opens generally. There is no public sign-up page yet, and we will not ask you for payment details during the preview.
To take part, tell us about your use case in GitHub Discussions, or e-mail Tractrix. You will receive an invitation to create an account.
Your data
Drawings and results belong to your organisation. Deleting an organisation deletes its projects, drawings and runs. The preview's data handling is described in the privacy notice.
Offline alternative
If your drawings may not leave your network, use Tractrix for QGIS, or the AutoCAD and Revit add-ins with the local engine. They run entirely on your machine.
