Synagy builds Minecraft mods and structures from one line of text – live in your world, tested before you touch them, yours to keep as a real .jar.
A real mod, yours to keep
“A copper magic mod: wands, an altar to recharge them, a ghost in old mines.”
Structures from vanilla blocks
“A water slide from a stone tower into a pool, with a ladder to the top.”
The Synagy Launcher sets up Fabric, the mod and a “Synagy” profile in the official launcher.
Pick Synagy Workshop in the main menu and right-click the Synagy Computer.
Choose Modding or Building and write what you want. At most three questions come back.
Every part with its price in credits. Remove, add, then confirm.
Parts form at the build altar, get tested and land in your world.
Right-click it in the Workshop world.
Plain words. Examples help you start.
Every part listed with its price in credits.
Parts form at the build altar while you watch.
Every part tested, then dropped into your world.
Ask for changes. Finish when you are happy.
Placeable, minable, with the right drops and world generation.
Recipes that craft, tiers that fit next to vanilla.
Full sets with textures, balanced against vanilla values.
Own 3D models, animations and behavior that spawn and move.
Stairs, doors, roofs, water runs – repaired until they work.
Right-click abilities, charging, projectiles, status effects.
Every part gets its own game tests: blocks place and drop right, recipes craft, mobs spawn and move. It compiles and starts without a crash before you see it.
Textures and 3D models are made for the vanilla style and checked against pictures of the real game, not just against the code.
Finish builds the final .jar with its source code into your Synagy profile. It works in every world, and you can publish it yourself.
Credits, no subscription. Each part shows its price before you build, and a part that fails costs nothing.
One account for the launcher, the game and this page. Pay as you go, failed parts are free.

Nothing to set up: the launcher installs everything and the chat runs inside the game, on Synagy credits.
Claude Code, Codex, Cursor and others build, check and playtest right inside Unity. Free package, one MCP server.
Minecraft: Java Edition 26.2 with Fabric, on Windows, macOS and Linux. We move to a newer version once Fabric and the popular mods are stable on it. Bedrock and NeoForge come later.
No. You describe what you want in plain words. The code is still yours: every mod comes with its full source.
No. Synagy plays in its own profile with its own game folder. Builds go into your worlds only when you place them there yourself.
Pay as you go with credits, no subscription. The plan shows a price for every part before anything is built; you pay what it really cost within that range, and failed parts are free. Signing up gives you 500 credits to start.
