Your own game developer, attached to your Studio.
Spawnly sits in a panel next to your Explorer and works like a developer on your team. It reads your place, plans, writes the scripts, builds the world and the UI, runs the game and fixes what breaks. Ask it for anything.

Things people type into it
Ask it for anything
Not one trick. Whatever a developer on your team would do, in the words you would use.
Game systems
Rounds, waves, checkpoints, leaderboards, shops, teams, timers. It wires the whole thing, not one script.
Add checkpoints for my obbyA round timer with a lobbyA leaderboard for kills
UI
HUDs, shops, menus and popups that fit a phone, checked for layout mistakes before it says done.
Add a coin counter to the HUDA shop that sells a speed boostA settings menu with a mute button
Worlds
Props, buildings, mazes, lighting, sky, fog, sound. Placed where you are looking, on the ground, checked for floating parts.
Make the lobby spookyBuild a small maze behind spawnPut a campfire by the cabin
Characters and tools
NPCs that talk, weapons that swing and hit on the server, vehicles that actually drive, pets that follow.
A sword that swings and drops lootA car by spawn that drivesAn NPC that says hi when I get close
Fixing
Paste the error or just say what is wrong. It reads the scripts, fixes the line, runs the game to make sure.
The door doesn't openCoins are wrong after rejoiningFind every script error and fix it
Testing
Before it says done it runs the game, reads the output and checks what it built. Errors get fixed before you see them.
Test the shop and fix what breaksCheck the obby for a gap
Planning and explaining
Big asks get a plan you can read first. Anything in your place, it can explain in plain words.
Plan a tycoon before building itWhat does DataSaver do?Explain how the round loop works
Built to live next to your Explorer
Chats, per place
Every place keeps its own chats and folders. Open a place and its history is there.
Credits in the header
The counter shows what you have. A finished request shows what it used.
Revert on every script edit
Under Changes, each edited script has a Revert button. Everything else undoes with Ctrl+Z.
Up and running in two minutes
Nothing to install on your computer beyond the plugin. No copying code across.

Say what you want
Type it the way you would tell a friend, then watch it read, build, run and fix.
Five models. Pick one per message.
| Model | Good for | Power | Price |
|---|---|---|---|
 DeepSeek V4 Flash | Cheapest. Quick edits and questions. | Power | Price |
 Gemini 3.8 FlashDefault | Fast everyday all-rounder. | Power | Price |
 Claude Sonnet | Systems, UI, fixes. | Power | Price |
 GPT-5.4 | Big features, tricky bugs. | Power | Price |
| Claude Opus | Whole games, hardest bugs. | Power | Price |
Power is the model's class, from its maker. Price is from its list price. Nothing is a score we invented. More about each model
Pay per request, nothing else
No subscription. Each request spends credits according to the model you picked and how much it had to read and do, and the exact number is on every finished request. Cheaper models go further; the price scale is in the picker before you send.

Not a chat box on a website
Other tools live on a site and paste a script into Studio. Spawnly lives in Studio, with hands in your place: it reads, builds, runs, checks and fixes while you watch.

Questions
Does it work on a place I haven't published?
Yes. It works in any place you have open in Studio, published or not. Chats are kept per place, so your history is there when you open it again.
Can it break my game?
Every script edit has a Revert button under Changes, and everything else undoes with Ctrl+Z. It asks before deleting anything, and it runs the game to check its own work before it says done.
What does it actually see?
Your place: the objects and the scripts, read fresh at the start of each request. It cannot see your screen. It sends what it needs to the model you picked, only while a request runs.
Does it use free models from the Creator Store?
When something is better fetched than built, like a tree or a bench, it searches the Creator Store, strips any scripts from what it finds and places it on the ground where you are looking. Ask for “from parts” and it builds instead.
What does a request cost?
It depends on the model and how much it had to read and do. A quick question on a cheap model is a credit or two; a whole system on the strongest model is more. The exact number is on every finished request, and the first 100 credits are free.
Do I need to know how to script?
No. Say what you want in your own words. If you do script, you will find it edits your existing code the way a teammate would, and explains what it changed.
