Buildcollaboratively.
Live cursors, presence, and a CRDT-backed editor that never desyncs. Pair-program across continents, voice-chat in-app, and review changes inline. Your whole team in one IDE.
Everything You Need to
Build on Solana
One IDE for every Solana stack. Build, collaborate, simulate, and ship without leaving the browser.
AI Pair Programmer
Context-aware completions, inline refactors, CPI suggestions, and tests generated by an assistant that actually understands your Anchor program.
Live Collaboration
CRDT-backed multi-cursor editing, presence, and inline comments. Your whole team in a single workspace.
In-App Voice & Video
Spin up a low-latency voice or video room next to your code. No tab switching, no extra tools.
Every Solana Language
First-class support for Anchor, native Rust, Seahorse (Python), and Solidity via Solang. One IDE, every stack.
Forgeflow Visual Builder
Sketch accounts, instructions, and CPIs on a canvas. Forgeflow compiles the diagram straight to production-ready Anchor.
Surfpool Sandbox
Personal validator that forks mainnet state, replays signatures, and inspects every CPI in isolation.
rust-analyzer Built-In
Hover docs, go-to-definition, intelligent refactors, and real-time diagnostics powered by a full LSP.
Bring Any Crate
Pull in custom Rust crates, cache them, and compile inside an isolated sandbox. Your dependency tree, your rules.
One-Click Deploy
Build, sign, and ship to devnet or mainnet-beta. Capture the program ID and verify on-chain in seconds.
GitHub, In-Context
Clone, fork, branch, and open pull requests without leaving the editor. No context switch, no lost work.
Integrated Terminal
A real shell wired to your sandbox, with anchor, solana, cargo, and spl-token preinstalled.
Project Templates
Start from curated Anchor, Seahorse, and Solidity templates, or fork any community project in one click.
Isolated & Secure
Per-user containers, multi-provider auth, encrypted storage, and signed deploys. Your keys never leave you.
Smart Diagnostics
Real-time error detection, lint hints, and security checks tuned for Solana programs and account layouts.
Fast by Design
Cached builds, incremental compilation, and edge-served previews keep the loop tight.
Community & Sharing
Publish projects, fork from other builders, and learn from a growing Solana developer community.
Mainnet Verification
Verify deployed programs against your source, capture the program ID, and prove provenance.
Installable PWA
Install BuildArena on desktop or mobile and launch your IDE like a native app. Offline-aware too.
Design programs visually.
Test them in your own sandbox.
Two new tools that turn the gap between “sketch” and “working program” into a single afternoon.
Visual program design
Drag accounts, instructions, and PDAs onto an infinite canvas. Forgeflow validates the graph in real time and scaffolds an Anchor program from your design. No boilerplate.
- Accounts, instructions & PDAs as first-class nodes
- Live graph validation with inline diagnostics
- Export to PNG up to 8K for docs and pitch decks
- Animated GIF exports show your program coming together
Your private Solana sandbox
Spin up an isolated Solana validator in seconds. Airdrop SOL, deploy programs, and point any wallet or @solana/web3.js client at your personal RPC URL. No local setup, no shared state.
- One-click validator boot, ready in seconds
- Unlimited devnet airdrops, capped per plan
- Authenticated RPC proxy works with any web3 client
- Auto-reaped on idle so you never pay for forgotten sessions
- Container-isolated per user, so your sandbox stays yours
