Developer launched Time Keep, a web app consolidating world clocks, timers, alarms, countdowns, a stopwatch, breaks, sleep planning, and Discord timestamp generation into a single interface to avoid juggling multiple devices and tabs. The tool works without signup (optionally saving data when signed in) and offers a Pro tier with live cross-device sync; shared countdown links auto-adjust to each viewer’s timezone. Built with Next.js, Supabase, Clerk, and deployed on Vercel, Time Keep targets productivity and real-time coordination use cases for distributed teams and individuals. Its quick-setup, no-account-first approach and timezone-aware sharing make it practical for remote work and scheduling across timezones.

A startup called Autonoma is scrapping 18 months of code and rebuilding after a series of pivots and growing pains. Despite customer traction and a recent funding round, the company accumulated tech debt from a no-tests, permissive TypeScript approach that led to bugs and lost clients. They originally built an ambitious agentic testing platform with complex Playwright/Appium wrappers and self-healing click strategies, but advances in LLMs reduced the need for heavy inspection logic. The rewrite will adopt strict TypeScript, tests-first practices, and ditch some previously chosen frameworks (notably Next.js Server Actions) in favor of simpler, more reliable approaches. The move aims to improve product quality, developer productivity, and long-term maintainability.

Author of Ozigi describes using Playwright network interception to E2E test a Next.js frontend that depends on LLMs (Gemini/OpenAI/Anthropic). Tests that hit live LLM APIs are costly, slow, and non-deterministic, so the article shows how to use page.route to intercept the Next.js /api/generate POST and fulfill it immediately with a static JSON payload. The piece includes a complete TypeScript Playwright script that navigates the dashboard, fills input fields, mocks the LLM response, triggers generation, and lets the UI render deterministic content (dynamic loader and campaign grid) for reliable assertions. This approach reduces CI costs, speeds tests, and eliminates flakiness from stochastic LLM outputs.

The 'Street Fix' app, designed for residents of informal settlements in Blantyre, Malawi, aims to enhance community engagement by allowing users to report local issues such as broken water points and waste collection problems. The platform features an interactive map, a community forum, and an admin dashboard for monitoring and managing reported issues. Built using Next.js, React, and Supabase, it emphasizes security and performance. This initiative addresses significant challenges faced by over 40% of Blantyre's population, fostering resource sharing and communication among residents. Its development showcases the potential of tech solutions in improving urban living conditions.

Ozigi’s creator detailed a v2 overhaul that turns the app from a monolithic Next.js MVP into an open-source, production-ready SaaS for generating social media campaigns from articles. The refactor breaks a large app/page.tsx into single-responsibility React components and centralizes TypeScript types in lib/types.ts, while adding localStorage state persistence to avoid resets. Backend changes move user data to Supabase with GitHub OAuth and PostgreSQL, automatically saving campaign history and storing user settings such as “Persona Voice” and Discord webhook URLs. New features include multi-modal ingestion (live URL plus custom text) and one-click Discord deployment via a dedicated API route. UI/UX updates add “try before you buy” guest mode gating and improved SEO metadata. QA adds rewritten Playwright E2E tests and CI fixes for Linux browser dependencies.

A university student from UTMACH in Ecuador has developed a carpooling app, UTMACH Rides, to address transportation challenges faced by over 14,000 students. The app, built using Next.js 16, Supabase, and Tailwind v4, allows verified students to connect for shared rides, enhancing safety and reducing costs associated with informal taxi services. With a focus on security, the app requires users to sign up with their university email, ensuring that only fellow students can access the platform. This initiative not only provides a structured way to coordinate rides but also aims to alleviate the financial burden and safety concerns students face while commuting to campus.
