dyad vs wasmer
Two of the top projects in App builder starters, side by side: who leads on each score part and who each one suits, then setup, license, activity and what each review found.
dyad
Desktop app that builds apps from prompts on your own machine
wasmer
WebAssembly runtime and CLI for running code in sandboxes
Verdict
dyad ranks higher, 89 to 85. Of the 4 score parts we measure for both, dyad leads on 3, wasmer on none and 1 is even.
- Adoptiondyad leads by 3 points, 80 to 77: close to even.
- FreshnessEven at 100.
- Maintenancedyad leads by 5 points, 88 to 83.
- Agent-readydyad leads by 15 points, 85 to 70: a wide gap.
Pick dyad if you are
Developers wanting a local Lovable/v0-style app builder with their own keys
- Runs locally as a desktop app, with no sign-up needed to download
- Bring your own API keys, so no hosted-platform lock-in
Pick wasmer if you are
Engineers embedding sandboxed code execution in apps or AI agents
- File, network and environment access is denied unless granted with flags such as --volume and --net
- Runs Python, Bash, PHP, SQLite and FFmpeg from a registry without installing them on the host

dyad
Dyad is a local, open-source prompt-to-app builder, positioned as an alternative to Lovable, v0 and Bolt that runs on your own computer. It ships as a downloadable app for Mac and Windows and uses your own AI API keys, with no sign-up. Code outside src/pro is Apache 2.0; src/pro is under the Functional Source License 1.1.
Who it is for: Developers wanting a local Lovable/v0-style app builder with their own keys
Strengths
- Runs locally as a desktop app, with no sign-up needed to download
- Bring your own API keys, so no hosted-platform lock-in
- Mac and Windows builds available
- Code outside src/pro is Apache 2.0 licensed
Weaknesses
- src/pro is fair-source (FSL 1.1), not fully open-source
- No Linux build mentioned in the README
- Desktop only; no Docker or self-hosted web deployment mentioned
- TypeScript
- Needs Your own AI provider API keys
- env example file
wasmer
Wasmer is a Rust WebAssembly runtime with a CLI that downloads packages from a registry (Python, Bash, PHP, SQLite, FFmpeg, PostgreSQL via pglite) and runs them in sandboxes. File, network and environment access are opt-in, for example via --volume and --net. Alpha SDKs for JavaScript, Python, Rust and Swift, kept in a separate repo, embed sandboxes in apps and agents.
Who it is for: Engineers embedding sandboxed code execution in apps or AI agents
Strengths
- File, network and environment access is denied unless granted with flags such as --volume and --net
- Runs Python, Bash, PHP, SQLite and FFmpeg from a registry without installing them on the host
- Same sandbox API across JavaScript, Python, Rust and Swift, including iOS and browser
- MIT licensed, with a Rust API and C API for lower-level WebAssembly embedding
Weaknesses
- The sandbox SDK is alpha and lives in a separate repository
- Rust SDK is a source dependency; crates.io publishing is currently disabled
- Browser execution needs cross-origin isolation headers on the page
- Not an agent framework or app builder; it provides only the sandbox layer
- Rust
