Claude Code vs Codex vs Rebirth for Roblox: Usage Limits and Price (2026)
Claude Code and Codex both work with Roblox Studio, but they stop you every 5 hours and every week. How their limits compare with Rebirth Unlimited.
prices and limits checked
The short version
- Claude Code and Codex can both build in Roblox Studio through Studio's own connection for AI tools.
- Both stop you twice: a limit that resets every 5 hours, and a weekly limit on top. Neither says exactly how much you get.
- To get rid of the 5-hour limit you pay $100 to $200 a month, and a weekly limit can still apply. Rebirth Unlimited is $29.99 a month with no credits, no 5-hour window and no weekly or monthly cap.
Yes, Claude Code and Codex work with Roblox Studio
Roblox Studio can act as a server for AI tools. Open the Assistant, pick Manage MCP Servers, turn on Enable Studio as MCP server, and Studio offers a quick connect for Claude Code, Codex CLI, Cursor and a few others (Roblox's guide).
After that, the agent in your terminal can run Luau in your open place, look at the screen and start a playtest. So the question isn't whether these tools can touch Roblox. It's what a day of building costs, and when they make you stop.
How Claude Code limits work
Claude Code comes with Claude's paid plans. Pro and Max have two limits that run at the same time:
- A 5-hour session limit. Use up the window and you wait for it to reset.
- A weekly limit. It resets on a fixed day and time for your account, even if every 5-hour window had room.
The two are shared with the normal Claude chat, so planning a game in the chat uses the same allowance as building it (Anthropic: using Claude Code with your plan). Anthropic doesn't publish exact numbers. You check what's left under Settings > Usage, or with /status in Claude Code.
| Claude plan | Price | Usage | 5-hour limit | Weekly limit |
|---|---|---|---|---|
| Pro | $20/mo ($17/mo yearly) | 1x | Yes | Yes |
| Max | $100/mo | 5x Pro | Yes | Yes |
| Ultra | $200/mo | 10x Pro, weekly | No (verified accounts) | Yes |
When you hit a limit you can wait, turn on paid usage credits, or switch to API credits billed per token (Claude pricing).
How Codex limits work
Codex comes with ChatGPT plans. Plus is $20 a month, and Pro starts at $100 (with $200 and $500 tiers) (OpenAI: Codex pricing).
On Plus, OpenAI gives a range instead of a number: for example 15 to 160 messages every 5 hours with GPT-6.1 Sol, or 350 to 3,000 with the lighter GPT-6 Luna. How many you actually get depends on how big each task is. Cloud tasks use more than local ones, and OpenAI says weekly limits may also apply.
Pro has no 5-hour limit right now, but weekly limits can still apply. When you run out, you buy credits or plug in an API key and pay per token.
How Rebirth Unlimited works
Rebirth only builds Roblox games. You type in your browser, and it builds, scripts and playtests inside your open Studio.
- Unlimited, $29.99 a month: no credits to count, no 5-hour window, no weekly or monthly cap. Up to 2 builds can run at the same time.
- Hobby, $8.99 and Pro, $15.99: credit plans where one prompt is one credit, whether it fixes one line or builds for an hour.
Unlimited is for one person building their own games. The fair-use rules in our Terms are there to stop shared accounts and bots, and only touch extremely heavy days. Our busiest builders send over 100 prompts on their biggest days and keep going.

Where Claude Code and Codex are better
They're general coding agents, and very good ones. If you also write websites, backends or tools outside Roblox, one subscription covers all of it. They work on any folder on your computer, use Git, and let you pick models and settings. If you like the terminal and already pay for Claude or ChatGPT, connecting them to Studio is a fine way to start.
Where Rebirth is better for Roblox
- Nothing to set up beyond the plugin. No terminal, no config files. Install the plugin, open the dashboard and type.
- It's built around Studio. Rebirth reads your place, writes and fixes scripts, builds parts and UI, then playtests the game, including two players at once, and looks at what happened.
- It remembers each game. Every game gets its own notes page that Rebirth reads before it starts and keeps up to date, so the next chat picks up where the last one stopped.
- The price doesn't move with the work. Long tasks don't drain a meter faster than short ones. On Unlimited there's no meter at all.
The bottom line
If Roblox is most of what you build, the limits are the real difference. Claude Code and Codex are great tools that stop you every 5 hours and every week unless you pay $100 to $200 a month. Rebirth Unlimited is $29.99 and doesn't.
