Devalyna - Developer ally for Solana

Inspiration

Web3 today runs on infrastructure, and Solana is one of the chains pushing the limits of speed, scale, and real-world adoption. But here’s the uncomfortable truth: if building on Solana is hard, then the entire Web3 ecosystem slows down with it.

And right now, getting started with Solana development is… painful.

The first wall you hit is tooling. Most of Solana’s official developer tools are tightly bound to macOS, with limited support for a few Linux distributions. That instantly locks out a massive portion of developers.

If you’re among the 60–70% of developers using Windows or non-Ubuntu Linux, you’re basically told: “figure it out yourself.”

This isn’t theoretical. It’s happening right now.

Friends of mine who recently started working as Solana developers had wildly different onboarding experiences :-> some took hours, some lost days, and a few literally bought new machines just to get a working Solana setup.

That friction doesn’t just hurt developers it hurts Solana, and by extension, Web3 itself Ouch!!!!.

That frustration is what sparked Devalyna. (Developer Ally for Solana)

Our goal was simple but ambitious make Solana development work anywhere, without installs, without OS limitations.

That decision led us to break apart Solana’s entire compiler toolchain and re-build it in one of the most portable execution targets available today: WebAssembly.

And that’s how Devalyna was born.

What Devalyna Does

Devalyna is essentially a next-generation, browser-native IDE for Solana. Think of it as Remix, but purpose-built for high-performance Web3 development on Solana.

At its core, Devalyna runs a WebAssembly powered version of Solana’s compiler suite, enabling developers to write, test, and deploy Solana programs directly from the browser no local setup required.

By designing a lightweight compiler and linker layer on top of the WebAssembly toolchain, and implementing a minimal JavaScript version of Solana’s program runtime syscalls, Devalyna dramatically reduces compile and test times.

We’re talking hundreds of milliseconds.

Compilation is fast enough that Devalyna can automatically rebuild and run tests every single time you change your code, turning development into a tight, real-time feedback loop.

The editor itself is powered by Treesitter, allowing Devalyna to construct and update full syntax trees for Solana programs in under a millisecond.

This unlocks an entirely new class of tooling that traditionally requires heavy local setups.

Some of the static analysis features enabled by Devalyna include:

automatic generation of TypeScript clients
auto-created serialization and deserialization logic
instruction and error union generation

From the same interface, developers can connect their Solana wallet, mint tokens and NFTs, request SOL airdrops, deploy or upgrade programs, and interact with the chain—all inside the browser.

No friction. No environment hell.

How We Built It

To make this work, we ported Solana’s modified LLVM backend and BPF toolchain to WebAssembly using Docker and Emscripten.

Because LLVM depends on a large number of system calls and native components, we chose not to port the full official clang/lld frontend. Instead, we wrote and cross-compiled a minimal custom frontend in C++, designed specifically for WebAssembly execution.

On top of that, we built a WebAssembly-based test runner, implementing key Solana program syscalls by directly studying Solana’s source code.

Everything was then tied together using React, Tailwind, and Solana Web3.js, with the editor layer built on Monaco Editor.

Given Monaco’s flexibility and the raw speed of our compiler; we integrated Treesitter to power deeper program analysis and unlock advanced developer tooling directly in the browser.
