openpilot Fork Comparison
Toggle the forks you want to compare. Select any two or more to see how they stack up across features, hardware support, and available branches.
There is no "best fork." Each fork is a different philosophy — stock openpilot is safest and most polished, FrogPilot is the most customizable, sunnypilot has the deepest model library and MADS, dragonpilot stays closest to stock, and vehicle-specific forks (StarPilot, OPGM, BluePilot, OPKR) exist because those cars need them. The joy of openpilot is trying them over time and finding what clicks for your car and driving style. A feature comparison can tell you what exists — only driving tells you what matters.
⚠️ Always try stock openpilot first before switching to a fork. All forks are unofficial and experimental.

🐸
FrogPilot
Community-driven. C3 re-support. The Pond web UI. Weather-aware driving.
Feature🐸 FrogPilot🌞 sunnypilot
comma 4 Support
Whether the fork runs on the comma 4 ($999, launched late 2025). Many community forks are still on comma 3/3X only.
❌ No
comma 4 is supported on the unified staging/dev branches. Stable release-mici is not available yet; check community.sunnypilot.ai for rollout updates.
comma 3X Support
comma 3X is the current recommended device for most community forks.
✅ Yes
✅ Yes
comma 3 (C3) Support
stock openpilot dropped C3 in v0.10.0 (Aug 2025). Several forks re-added or maintained support. sunnypilot C3 (TICI): no stable branch yet. Use staging-tici (install.sunnypilot.ai/staging-tici). C3 support is maintenance-mode — C3X (TIZI) is the actively supported platform.
✅ Yes
✅ Yes
Feature🐸 FrogPilot🌞 sunnypilot
Always On Lateral (AOL / MADS)
Steering assist stays active even when you touch the brake or accelerator.
✅ Yes
✅ Yes
Auto Lane Change
Automatically changes lanes when blinker is activated.
✅ Yes
✅ Yes
Auto Lane Change Timer
Configurable delay before lane change — no steering nudge required.
✅ Yes
✅ Yes
Increased Steering Torque
Higher torque on select vehicles for better lane holding. Note: 2018–22 Honda Accord already runs at hardware max torque (4096) in stock openpilot — the real upgrade for Honda owners is NNFF/NNLC neural network lateral control, not the torque cap.

Neural Network Lateral Control (NNLC/NNFF)
Neural network trained per-vehicle EPS firmware. Smoother, more accurate steering. Originated by @twilsonco.
✅ Yes
✅ Yes
Feature🐸 FrogPilot🌞 sunnypilot
Conditional / Dynamic Experimental Mode
Auto-switches Chill/Experimental mode based on road context. FrogPilot: CEM. SunnyPilot: DEM.
✅ Yes
✅ Yes
Speed Limit Control (SLC)
Auto-adjusts cruise speed to posted limits using map data and/or car interface.
✅ Yes
✅ Yes
Vision Turn Speed Control (V-TSC)
Slows before corners using vision model.
✅ Yes
✅ Yes
Map Turn Speed Control (M-TSC)
Slows before corners using OSM map data.
✅ Yes
✅ Yes
Driving Personalities / Profiles
Named profiles (Traffic, Aggressive, Standard, Relaxed) with tunable following/acceleration.
✅ Yes
✅ Yes
Gap Adjust Cruise (GAC)
Change following distance on-the-fly via steering wheel gap button.
✅ Yes
✅ Yes
Traffic / Maniac Mode
Aggressive stop-and-go profile. FrogPilot: Traffic Mode. SunnyPilot: Maniac Mode.
✅ Yes
✅ Yes
Human-Like Accel / Braking Profiles
Tuned acceleration and braking curves that feel more natural than stock. FrogPilot: 'Human-Like Acceleration' (faster pull) and 'Smoother Braking' — configurable per personality profile. StarPilot: GM-specific VoACC tuning plus inherited human-like accel/braking profile controls. sunnypilot/others: follow stock openpilot longitudinal model without additional tuning layers.
✅ Yes
❌ No
Lead Detection Tuning & Adjacent Lead Tracking
Customizable lead car detection sensitivity and adjacent lead tracking during lane changes. FrogPilot and StarPilot: adjustable detection thresholds (detect leads sooner/farther), plus Adjacent Lead Tracking — when changing lanes, it tracks the speed of the new lane's lead and smoothly adapts before the lane change completes. Most forks use stock openpilot detection with no tuning.
✅ Yes
❌ No
Per-Range Speed Limit Offsets
Set different speed offsets for each speed limit range (e.g., +5 at 25 mph, +7 at 45 mph, +10 at 65 mph). FrogPilot and StarPilot: configurable offset per major speed range. sunnypilot: single flat % offset applied globally. dragonpilot/OPKR: flat offset or none. More granular = more natural real-world cruising.
✅ Yes
❌ No
Learning Curve Speed Controller
A curve speed system that learns your preferred speed through curves over time — not just a fixed slowdown factor. FrogPilot: CSC adapts to your actual inputs and trains from your driving behavior. StarPilot: CSC included and actively used. V-TSC/M-TSC in other forks use fixed thresholds without learning.
✅ Yes
❌ No
Feature🐸 FrogPilot🌞 sunnypilot
Offline Maps
Download map regions for offline speed limit and road data.
✅ Yes
✅ Yes
Speed Limit Sources
Where speed limit data comes from.
OSM + Mapbox + Car
OSM + Car + HDA (HKG)
Feature🐸 FrogPilot🌞 sunnypilot
Custom Themes

A few notes
- ⚠️ All forks are unofficial. Comma.ai does not support or endorse them.
- ⚠️ Feature support changes frequently — always verify on each fork's GitHub.
- ⚠️ "Partial" means the feature exists in a limited or different form.
- 🧪 ADAS is not self-driving. Always pay attention.
- 📦 comma 4 launched late 2025. As of March 2026: stock openpilot has full C4 support. sunnypilot has dev/staging C4 branches. StarPilot supports C4 on the same installer as C3/C3X (first fork to cover all three — C4 still beta). FrogPilot, dragonpilot, BluePilot, and OPKR are C3/3X only. OPGM C4 status is unconfirmed.
- 🔄 sunnypilot: C3X stable at release.sunnypilot.ai (release-tizi). C3 has staging-tici only (no stable yet). C4 stable (release-mici) coming soon. staging/dev branches are unified for C3X+C4.
- 🔄 FrogPilot's The Pond (local web dashboard) is reportedly transitioning to a cloud-based platform similar to SunnyLink — not yet live as of early 2026, check the FrogPilot Discord for updates.
- 🐉 dragonpilot GitHub moved to github.com/dragonpilot/dragonpilot
- BluePilot, OPKR, OPGM, and StarPilot are vehicle-specific forks — toggle them in to compare.
- ⭐ StarPilot is an openpilot fork for GM/Bolt drivers. Originally started within the FrogPilot Universe, it has since branched off in its own direction. Supports C3, C3X, and C4 on a single installer: installer.comma.ai/firestar5683/StarPilot
