AI Plugin for Roblox Studio: Forge AI vs Others

A side-by-side look at the AI copilot plugins available for Roblox Studio today. We compare code generation quality, project intelligence, 3D model generation, audit tools, and pricing — feature by feature, with measured eval numbers for Forge.

Last measured: 2026-04-27. We only publish numbers we can verify ourselves; cells under Others reflect public marketing claims of AI plugins available in the Roblox Creator Store at time of writing. Spotted a stale entry? Email samet@loopmobile.io and we'll re-test.

Measured: Forge codegen eval (April 2026)

30 Roblox Studio prompts × 3-layer lint (pattern + luau-lsp typed analysis + LLM-as-judge). Methodology and prompts in scripts/eval-final-summary.md.

Why developers pick Forge AI as their Roblox Studio plugin

  • Verified Luau. Every script passes loadstring parsing and 16 Roblox API hard-checks before it lands in your project. Other AI plugins ship code that compiles in their own tester but fails inside your Studio.
  • Recipe-backed. 80+ vetted system templates (combat, pet, tycoon, FPS, boss fight, lobby, parkour) feed every codegen turn. The alternatives hand-write each system from a generic LLM, with predictable variance.
  • Beyond code. Text-to-3D mesh generation, curated asset library, automated 100-point game audit, performance profiler, anti-cheat scan — none of which the other Roblox Studio AI plugins offer today.
  • Honest pricing. Per-action credit cost is published — Sonnet chat 5 credits, 3D model 15, thumbnail 2. You always know what your next operation costs.

Choosing the right AI plugin for Roblox Studio

An AI plugin for Roblox Studio should do four things well: write Luau that actually runs, understand your existing place hierarchy, generate the 3D and UI assets your prompts ask for, and stay out of the way. Most plugins handle the first one. Forge AI is the only Roblox Studio AI plugin that ships all four in a single install.

For new Roblox developers, the right AI plugin doubles as a teacher — Forge labels every generated system, ticks plan steps live, and explains the Luau it produced. For studios already shipping games, the differentiator is verification: Forge runs --!strict by default, lints with luau-lsp, and rejects unsafe API calls before they leave the plugin.

If you're comparing AI plugins for Roblox Studio side by side, the table above is the short answer. If you want to see Forge AI build specific systems in real time, jump to the step-by-step guides: combat system, tycoon, obby, pet system, FPS, boss fight, plus 6 more on the how-to index.
