Dylibso provides a lightweight WebAssembly runtime that enables developers to embed portable, sandboxed plugins into native applications across Windows, Linux, macOS, and embedded devices. The platform offers APIs for dynamic loading, versioning, and cryptographic signing, plus AI‑assisted tooling to generate optimized Wasm modules from Rust, C++, or Go.

Problem
Modern applications often require extensibility to add new features or integrate third‑party logic, but traditional plugin systems are tied to specific operating systems, languages, or runtime environments. This creates maintenance overhead, security risks, and performance penalties when developers need to support diverse deployment targets. Consequently, teams spend significant effort building custom bridges rather than focusing on core product value.
Solution
Dylibso offers a platform that lets developers embed WebAssembly (Wasm) modules as native extensions within existing applications. The service provides a lightweight, sandboxed Wasm runtime that can be linked at build time or loaded dynamically at runtime, delivering near‑native performance while isolating execution. Modules are compiled once to a portable binary format, enabling the same plugin to run on Windows, Linux, macOS, and embedded architectures without recompilation. An AI‑assisted tooling layer helps generate and optimize Wasm code from source languages such as Rust, C++, or Go, reducing the learning curve for teams unfamiliar with Wasm. The platform also supplies APIs for registration, versioning, and lifecycle management, allowing applications to adopt a true dynamic plugin architecture. All interactions are secured through cryptographic signing and runtime sandbox policies, ensuring that third‑party code cannot compromise host integrity.
Target Audience
The primary customers are software engineering teams building extensible SaaS platforms, enterprise applications, or IoT firmware that need secure, high‑performance plugins across heterogeneous environments.
Features
- Integrated Wasm runtime with deterministic sandboxing and configurable memory limits
- Zero‑copy data exchange between host and Wasm module via shared buffers for low‑latency calls
- Cross‑platform binary compatibility: a single .wasm file runs on x86_64, ARM, and Web environments
- AI‑driven code generation assistant that converts supported source languages into optimized Wasm modules
- Dynamic loading/unloading API supporting hot‑swap of plugins without restarting the host application
- Cryptographic module signing and runtime attestation to enforce provenance and prevent tampering
- Built‑in performance profiling tools that report execution time, memory usage, and CPU cycles per call
- CI/CD integration hooks for automated testing, versioning, and deployment of Wasm plugins
