Code Arena just leveled up with fullstack capabilities 🚀 Introducing the new Fullstack Code Arena. We’re moving beyond frontend prototypes to fullstack development complete with databases, API keys, and fast deployments. Build, iterate, and ship real-world software — all in one place. Models now act as agents in the... Code Arena, using structured tool calls to plan, execute, and refine in real time with real world tasks. Read more about it in the thread 🧵show more

With Fullstack, we now support building more complex apps that require database or backend functionality. Code Arena now powers building a whole new suite of apps you couldn’t before, including: - Apps that require a sign up or login flow, such as admin portals or dashboards - Apps that use an API key, like an AI chatbot - Apps that store a user’s progress for them to come back to, such as an online education or teaching app This changes Code Arena from more of an experimental prototyping environment to a daily-use tool where real work gets done. The votes will power a future Fullstack leaderboard. Click through to our YouTube to watch the full walkthrough of Fullstack Code Arena:

@arena dude, this is huge! finally a place to play with fullstack ideas without setting up a billion things first. gonna save so much time 🏆

Honestly insane we're going from frontend mockups to agents deploying fullstack with real DBs. What happens when an agent hits a prod edge case though? Human override or full automation?

Good move. Frontend-only benchmarks stopped meaning much a while ago. Real work is databases, auth, deploys, all the boring plumbing. Testing models on "can it ship" instead of "can it code" is the right bar.

do you guys realize how hard it is for a general user to comprare two sometimes huge stacks? their voting wouldn't really show the actual thing, unless it is just about the looks and functionality, if that's what you're targetting here.

Moving from frontend prototypes to full databases and deployments is a big jump for a benchmark tool.

Can we have the reverse of this, where you vary the fullstack framework for each model.

yo

Huge upgrade.

wow

hey

Amazing Code Arena Fullstack unlocked DBs, APIs, live deploys + agent tool calls. Prototype → ship, all in one place

hi

I think this will produce thr most realistic insights on model capabilities.

When I wired up database auth in a fast-deploy sandbox, service_role was the default that bit me. It bypasses RLS entirely, looks clean in preview, and exposes every row to every authenticated user once it's live.
