Epica Beauty launches free AI face shape detector powered by Claude Vision

·4 views

Beauty platform Epica Beauty has released a free tool called testmyface.com that identifies a user's face shape from a single selfie using Claude's vision API. The tool classifies faces into one of six shapes — oval, round, square, heart, diamond, or oblong — and returns styling suggestions along with a confidence score. Built on a simple stack of static HTML hosted on Vercel and a single serverless function, each analysis costs roughly $0.003 and takes only a few seconds. No user account is required, and uploaded photos are never stored to disk, passing directly from the browser to the API and back. The team noted that the most challenging part of development was prompting the model to commit to a single face shape classification rather than hedging between two options.

Mem0 vs TurboMem: Comparing Memory Layers for TypeScript AI Agents

Developers building AI agents in TypeScript now have two main memory layer options: the well-established Mem0 and the newer TurboMem. Mem0 operates as a separate service requiring infrastructure such as Postgres with pgvector and optionally Neo4j, meaning every memory operation crosses a process boundary. TurboMem takes an opposite approach by running entirely inside the Node, Bun, or browser process as a native TypeScript library, eliminating network hops and external database setup. While Mem0 is framework-agnostic and Python-first with a TypeScript SDK available, TurboMem is built ground-up for TypeScript with Zod-validated inputs and support for edge runtimes like Cloudflare Workers. The choice largely depends on stack preference: Mem0 suits teams needing a standalone memory service, while TurboMem targets TypeScript-focused teams wanting memory to work like a standard imported library.

Full-Stack Dev VikingRob Seeks Collaboration Amid Tough Freelance Market

Robert, a full-stack developer known online as VikingRob, has introduced himself to the DEV Community as a solo entrepreneur and freelancer navigating a highly competitive job market. He has been sustaining income partly through passive revenue from selling self-built front-end and back-end websites, though he notes this is insufficient for consistent family support. He is the primary provider for a family of five, including a spouse managing serious mental health challenges, adding urgency to his search for stable work. To address the shifting market, he is expanding his service offerings to include custom website architecture, advanced back-end integration, and SaaS product development. He is reaching out to the developer community for potential collaborations and is also seeking advice from peers on how others are cutting through the noise in the current freelance landscape.

Linaria Maintainer Builds dx-styles to Fix Zero-Runtime CSS-in-JS Gaps

The maintainer of Linaria and creator of wyw-in-js has launched a new styling library called dx-styles after six years working on compile-time CSS-in-JS tooling. Two recurring problems with Linaria drove the decision: component interpolations in styled templates frequently break static evaluation, and the library lacks first-class support for variants, tokens, and multipart components central to design systems. Fixing both issues would require breaking changes incompatible with Linaria's existing user base, so Linaria will remain maintained while dx-styles starts fresh. The author also noted that slow build times — sometimes consuming tens of minutes and gigabytes of RAM — pushed the new tool toward maximizing static evaluation at compile time. dx-styles is designed for teams building design systems who want typed styles and structured theming without runtime overhead.
