    WasmEdge is a lightweight, high-performance, and extensible WebAssembly runtime for cloud native, edge, and decentralized applications. It powers serverless apps, embedded functions, microservices, smart contracts, and IoT devices.

    Project mention: WASM's "Identity Crisis" Is Actually Its Superpower | dev.to | 2026-05-04

    When TensorFlow.js offered a WASM backend, inference performance improved by 10x on CPUs. The WasmEdge runtime enables computer vision models to run on Raspberry Pi devices with sub-10ms inference latency. Cloudflare Workers now serve ML inference requests with zero cold start penalty.

  2. AppSignal

    Monitoring that respects your time & budget. APM, error tracking, and dashboards for modern web apps. Ten-minute setup, transparent flat pricing, and support from engineers who actually use the product.

    Project mention: Why AI Apps Fail in Production (And How Google Solved It) | dev.to | 2026-07-22

    A Safe, Live Data Layer: Instead of testing in a vacuum with fake data, developers bootstrap ideas using Google AI Studio templates. These hook into a secure Google Cloud proxy server that grants pre-authenticated, read-only API access to live components - like playlists, videos, and channels. You get technical accuracy without any risk of polluting or crashing core databases.
