The software that tells you when your robot is about to get into trouble.

Modules exist underneath — ArcFlight, ArcGround, ArcSim, ArcSwarm — but the operator works in verbs. You don't launch a module. You open your system, and ArcForge presents the right surface for what you're doing.

Compose a vehicle from a parts catalog, reconcile the design against detected hardware, and know before you build whether it will work.

• Domain-aware readiness. Pick a 4-wheel chassis and the platform expects four motors and four wheels. Skid-steer omits steering; Ackermann needs it — and Sketch tells you which is which.
• "Will it fly?" Physics prediction computes mass-sensitive hover current and endurance from the parts catalog before anything leaves the bench — air and ground.
• Design ↔ hardware reconciliation. When real hardware arrives, ArcForge compares it to the design, names every difference, and recommends adjustments.
• Every value carries its source. Detected, Assumed, or User Override — configuration provenance the operator can trust.

ArcSim is the rehearsal layer — three live modes plus replay, all on the same recorder format as live operations. Test the mission before the mission.

One action pushes a verified configuration to the edge. Not a checklist you maintain — a gate the platform enforces.

• Signed end-to-end. Every deploy ships as a signed manifest. The receiving computer verifies the signature and every file digest before a single byte is written.
• Prerequisites, not surprises. Companion reachable, controller detected, required sensor topics present, ROS stack running — the Deploy button physically cannot be pressed until the system is actually ready, and every blocked item says exactly what to fix.
• Fail-closed by design. If ArcForge can't confirm a prerequisite, it doesn't guess. The platform refuses to advance under uncertainty.

A cockpit engineered from operator cognition backward — live video, telemetry HUD, route planning, and payload control in one surface that adapts to the vehicle you opened.

• Contextual cockpit. Open a drone, get the flight cockpit. Open a rover, get the ground cockpit. Same shell, same skills, same recorder underneath.
• Viewport-payload swap. Promote any visual payload — CV detections, thermal, LiDAR, map — into the primary view at runtime. The operator decides the visual hierarchy, not the software.
• Command transport you can trust. Authenticated, encrypted, tunnel-only, regression-tested. There is no plaintext fallback to force.
• ArcAssist reliability supervision. Fourteen reliability engines consolidated into one panel that names the worst active issue and states what the platform did about it — including gating commands when the vehicle isn't safe to command.

Every capability lands with its verification gates. The discipline is the product.

ArcForge v0.7.0-beta.2 — free during the beta. Simulation works out of the box; connect an ArduPilot vehicle when you're ready.

Beta builds are unsigned. macOS: right-click the app → Open (or System Settings → Privacy & Security → Open Anyway). Windows: choose "More info" → "Run anyway" at the SmartScreen prompt.

Start free in simulation. Bring a vehicle when you're ready — even if it's just a flight controller.
