There are more than two dozen Roblox executors on the market in 2025, but only four of them are downloaded more than a million times a month: Delta X, Wave, Solara, and Codex. Each one has different strengths and weaknesses, and the "best" choice depends on what you actually want to do. This guide compares them head-to-head across every metric that matters — UNC score, ban rate, Script Hub size, mobile support, pricing, and anti-detection — so you can make an informed decision.
The TL;DR — Which One Should You Use?
If you want the short answer:
- Pick Delta X if you want the highest UNC score, the lowest ban rate, mobile support, and the largest Script Hub. It's free, cross-platform, and the safest choice in 2025.
- Pick Wave if you only play on PC, want a lightweight executor, and don't mind the slightly higher ban rate.
- Pick Solara if you're willing to pay for premium stability and don't need mobile support.
- Pick Codex if you primarily use an Android emulator (LDPlayer, MuMu) on PC.

Delta X — The All-Round Leader
Delta Executor has been the most-downloaded Roblox executor since 2023. It leads on every metric except VirusTotal score (where Solara is technically cleaner because it doesn't ship a kernel-mode driver) and price parity with paid tools. The headline numbers: 98% UNC score, 0.3% ban rate, 4,500+ scripts in the Hub, full cross-platform support including iOS via AltStore, and a 30-second mobile key flow.
The single biggest differentiator is Delta's kernel-level injection. Every other major executor operates at userland, where Roblox's Byfron / Hyperion anti-cheat can observe memory writes and either crash the game or silently flag the account. Delta allocates its Lua runtime at ring-0 via a signed Windows driver — the anti-cheat hooks are userland-only, so they can't see what Delta does. That's why Delta's ban rate is 6× lower than Wave's and 8× lower than Solara's.
The tradeoff is the Defender false positive on Windows (a known issue that affects all kernel-mode tools and is fixed by adding the folder to exclusions). For most users, this is a minor inconvenience worth paying for the ban-rate advantage.
Wave — The Lightweight PC Choice
Wave is the second-most-popular executor in 2025 and the best choice if you only play on Windows and want a small, fast tool. The installer is 18 MB (vs Delta's 24 MB), the UI launches in under a second, and the executor uses 40% less RAM than Delta. If you're scripting on a low-end laptop, Wave is noticeably snappier.
The downside is a 92% UNC score (vs Delta's 98%), a 1.8% ban rate (6× higher than Delta), and no mobile support. Wave's anti-detection is userland-only, so it's much more vulnerable to Byfron's hooks. Wave's script hub is also smaller — 2,200 scripts vs Delta's 4,500+.
Wave is free with a key system similar to Delta's. The key takes about 60 seconds to get (vs Delta's 30). Wave is a solid tool but Delta is simply a generation ahead.
Solara — The Paid Stability Pick
Solara is the most established paid executor on the market, costing $15/month or $80/year. It's Windows-only, userland, and has an 88% UNC score — the lowest of the four. So why do people pay for it?
Two reasons. First, Solara is the most stable executor — its crash rate is the lowest in the industry because it rejects scripts that might cause issues. Second, Solara has a reputation for never distributing malware — the 0/72 VirusTotal score is genuine, and Solara's developer team is openly identified, which is unusual in this space.
But Solara is showing its age. No mobile support, no built-in Script Hub, manual-only patching, and a 2.4% ban rate. At $15/month you're paying a premium for stability you can get free from Delta. The only users who should still pick Solara are enterprise script developers who need the absolutely-most-stable Windows environment.
Codex — The Android Emulator Specialist
Codex is a niche tool built specifically for running inside Android emulators (LDPlayer, MuMu Player, BlueStacks) on Windows. It's the go-to choice if you want to script Roblox on your phone but your phone is too old or weak to run Delta directly.
Codex runs inside the emulator's Android container, so it bypasses the iOS-style restrictions that block most executors on real mobile devices. It has a 90% UNC score, a 1.5% ban rate, and a 1,800-script hub. The key system is similar to Delta's.
The downside is that Codex requires you to set up an emulator first — which is a heavy lift (5-10 GB of disk space, 4-8 GB of RAM, and a decent CPU). If your PC can handle an emulator, you might as well use Delta directly on the PC and skip the emulator overhead.
Use-Case Recommendations
"I want the safest, lowest-ban-rate executor"
Delta X. 0.3% ban rate is unbeaten.
"I want to script on my phone"
Delta X on Android (real device) or Delta X on iOS (via AltStore). Codex is a fallback if your phone can't run Delta directly.
"I want the largest Script Hub"
Delta X — 4,500+ scripts, all pre-verified.
"I want the lightest, fastest PC executor"
Wave — 18 MB, launches in under a second.
"I'm a professional script developer and need maximum stability"
Solara (paid) or Delta X (free). Both have excellent crash-free uptime.
"I want zero risk of malware"
Delta X or Solara. Wave and Codex have higher VirusTotal scores and have had minor malware scares in 2024.
Bottom Line
Delta X is the best all-around Roblox executor in 2025 by every metric that matters. It wins on UNC score, ban rate, Script Hub size, mobile support, and price. Wave is a respectable runner-up for PC-only users who want lightweight speed. Solara is a legacy paid option for stability purists. Codex is a niche Android-emulator tool.
If you're still deciding, just install Delta — it's free, it takes 30 seconds, and you'll know within a minute whether it's the right tool for you. Read our intro guide to get started.
