PD Replica
Builds the world from your data
4D digital twins of the places you operate, built from your own drive, drone and indoor logs, each with a quality report.
Your data. Generate thousands of verifiable simulations.
A platform powered by our proprietary foundation model and PD Replica technology that enables agents to take you from capture logs to a program scale simulation suite in hours. Everything can be driven by agents, code, or UI.
Your team runs every step in one workspace.
- 01

PD FormaPD Forma: curate, configure and reconstruct, then check the quality report.
- 03
Publish
One click shares the Replica across your organization.
PD Sim
Runs your system inside it
Camera, lidar and radar simulation for developing, training and testing at program scale, cloud-hosted or self-hosted.

Plan
PlannerPlanner turns a Replica into the scenarios you need.
- 05
Simulate
Test any time, any season, with any actors.
Every step runs from the web app, the CLI, the Python SDK or agents, with Replica tokens and compute usage in one place.
Verifiable
Every Replica ships with a quality report that compares the render against the real capture, camera by camera.
Shared
Generate once, publish to your whole organization. Every engineer simulates on the same validated Replica.
Automatable
Agents, the CLI and the Python SDK can drive everything the web app does, so simulation fits into your pipelines.
Generate with PD FormaNew
Generate your own Replicas, end to end
PD Forma brings 4D Replica reconstruction, quality assessment and scenario extraction into one pipeline. Your team runs it directly, without waiting on anyone and without the engineering bandwidth it takes to use other simulators. Generate a Replica once, then publish it to your whole organization.
- 01
Connect
Register logs and validate them before you spend a Replica tokens.
- 02
Curate
Pick the region, logs and budget on a satellite map.
- 03
Configure
Choose the type, size, resolution and feature set.
- 04
Monitor
Follow stage-by-stage logs and monitor progress in real time.
- 05
Review
Quality reports quantify and qualify each reconstruction so you can trust simulation at scale.
- 06
Publish
One click shares the Replica across your organization.
Plan with Planner
Turn a Replica into the scenario you need
Planner opens any Replica as an editable scenario. The agents in your log are already extracted, each with its own route. Replay what happened, then change it.
Scenarios straight from your logs
The ego vehicle and every tracked agent arrive with their routes, ready to replay.
Edit routes, timing and actors
Change waypoints and motion, add or remove actors and assets, and trim the scene on a multi-track timeline.
Plan with AI
Describe the change you want and refer to any actor by name. The assistant proposes scene edits for you to review before you apply them.
Validate before you simulate
Clearance checks flag overlapping agents across the whole scenario, so you can fix them before running.
Map and 3D views
Work on a road-network map or inside the reconstructed scene.
Simulate with PD Sim
Capture once. Test any time, any season, with any actors.
PD Forma keeps the scene’s geometry and changes the conditions, so you can see how your system responds when the environment changes. These are hard to capture consistently in the real world. Then open the scene in Planner to add, remove or retime the actors.
Run PD Sim your way
In the browser, in our cloud, or in yours
Start an instance and write code against PD Sim right in your browser, with nothing to install. When you're ready to scale, run in our cloud or on your own hardware.
Web IDE
Every PD Sim instance comes with a browser-based code editor, terminal and viewer. Write a scenario, run it and inspect the results, with no install required.
Cloud-hosted
Launch PD Sim instances from the web app and scale to the size of your run, with no GPUs to buy or manage.
Self-hosted
Run PD Sim on your own hardware, on-premises or in your own cloud account, when your data has to stay inside your network.
Manage your usage
See how your organization uses simulation
Every Replica you publish is shared across your organization, and program leads get a clear view of where Replica tokens and compute are going, across every team and project, without asking anyone for a report.
Replica tokens usage
total consumed, jobs run, daily average and peak day for any date range, with a day-by-day chart.
Cost on every job
a Replica tokens estimate before you run and the Replica tokens charged once it completes.
Simulation data
gigabytes generated in PD Sim per day, broken down by user.
Live capacity
cloud instances in use against your allowance and anything waiting in the queue.
Filter by person
projects, jobs, datasets and transfers.
Team management
manage organization members in one place.
Explore
A library that keeps growing, and the tools to manage, search, and serve.
Start from a large and growing collection of Replica locations, procedural worlds, assets and lighting. We add more every release, so there's always somewhere new to test. Upload your own assets and generate your own worlds from your capture logs with PD Forma.
Replica locations
Real places reconstructed from drive and drone captures, many with OpenDRIVE road networks attached.
Assets
About 8,000 props, signs and traffic-control objects, each previewed and searchable by category.
Lighting
Dawn and daytime presets, from clear skies to cloudy, ready to apply to any scene.
Custom assets
Upload your own 3D props. They stay private to your organization and are ready to place in any scenario, right alongside the PD library.
Automate the whole pipeline
Everything in the web app is also available from code. Register data, configure and launch jobs, monitor stages, and publish to sim without opening a browser, so Replicas can be part of your CI or data pipeline. Then create simulations, scenarios, and variants in code, manage them through our CLI, and run at scale. Use our agentic skillsets to automate the work for you, building simulation suites while you sleep.
