Show HN: Helix – AI-powered API mocking with strict schema enforcement https://ift.tt/Ej06ukA

Show HN: Helix – AI-powered API mocking with strict schema enforcement Helix is a dynamic mock server that generates data on the fly using LLMs (supports Ollama, DeepSeek, Groq). Key difference from other AI generators: Schema Enforcement. One of the biggest issues with LLMs is non-deterministic output. To solve this, Helix allows you to provide a "System Schema" (using TypeScript interfaces, JSON Schema, or plain text rules). The engine ensures the generated JSON strictly adheres to your defined keys and types, while still generating realistic values for the content. Features: - Local-First: Works completely offline with Ollama (Llama 3.2 is recommended). - Schema Safety: You can force strict structure compliance so your frontend doesn't break. - Chaos Mode: Optionally simulate latency and error rates. - Stack: Python 3.11, FastAPI, Redis, Docker. It's open source (AGPLv3). I'd love to hear your feedback, especially regarding the schema validation approach! Repo: https://ift.tt/nFemi5o https://ift.tt/nFemi5o December 19, 2025 at 05:28AM

Show HN: MephistoMail – RAM-only ephemeral email with client-side privacy tools https://ift.tt/U2kzHoN

Show HN: MephistoMail – RAM-only ephemeral email with client-side privacy tools Hi HN, I’m building MephistoMail, a privacy-focused disposable email service designed to decouple digital identity from online services. After seeing how many "temp mail" providers log IP addresses or sell metadata, I wanted to build something that prioritizes total digital hygiene. New Key Features: Volatile Memory Storage: We use a RAM-only infrastructure. No incoming messages or session data are ever written to a physical HDD. Once the session terminates, the data is cryptographically wiped. Client-Side Password Generator: Integrated entropy-based generator that runs locally in your browser. Create high-security passwords for your registrations without them ever touching our servers. Secure QR Handoff: Transfer your active "burner" session from desktop to mobile instantly via an encrypted QR link. No need to type complex random addresses on your phone. Multi-Account Tunneling: Manage multiple anonymous identities simultaneously through a unified interface. Custom Alias Creation: Define your own usernames on our secure domains for more professional-looking temporary identities. The Stack: Frontend: React, Tailwind CSS, Lucide icons. Backend Logic: Powered by Mail.tm's stable API for zero-latency delivery. Privacy: Strict No-Logs policy, TLS 1.3 encryption, and no tracking cookies. I’m looking for technical feedback on the UX and the "Persona" tool integration.
