[Other] Show HN: Loopletter: Open-source email marketing platform Hi, I started building Loopletter, an open-source email marketing platform built specifically for independent artists and creators. I&#x27;ve been using this for a while to run marketing campaigns for my own company. But due to the lack of time to update it i&#x27;ve decided to open it up under the MIT license so other people and industries can self-host, extend, or just learn from the codebase.<p><pre><code> What’s inside: - Full campaign builder (visual editor, reusable templates, optional Spotify-powered layouts) - Audience management tooling (imports, segmentation, consent workflows, list cleanup) - Queue-driven sending with AWS SES, BullMQ, and Redis — handles rate limits, retries, and deliverability feedback - Analytics dashboards with real-time metrics, campaign history, and basic attribution - Infrastructure scripts for Supabase, AWS EventBridge&#x2F;Lambda, and Upstash Redis so you can set everything up from scratch Tech stack: Next.js, React 19, TypeScript, Tailwind, Clerk for auth, Supabase (Postgres) for storage, AWS SES + S3 for mail&#x2F;asset delivery. The repo has docs, scripts, and a demo data sandbox because we know email platforms can be boring to set up without real content. Why open-source? Most tools in this space are either huge enterprise SaaS products or very marketing&#x2F;sales oriented. Independent artists have different needs (merch drops, tour announcements, limited release windows) and usually lean on social platforms they don’t control. Email still converts best for them, but standing up a full stack is painful. We’d love to see small labels, agencies, and indie devs fork it, run it for their communities, or contribute features. I&#x27;m especially curious if this has potential to be something bigger.

Thanks for taking a look!</code></pre>

[Other] Show HN: I build a cheap Skype Clone I build a skype clone, where you can make international calls via browser.<p>Skype was my go to app for that, but since they shut it down, decided to build my own. Its perfect for calling international customer support, or any other gov numbers.<p>Its pay-as-you-go - so no subscription charges, very transparent pricing. You can just top up $5 and see pricing in real time during the call.

[Other] ai-sdk-panel: the config panel for ai sdk. The LLM Providers editor for ai sdk providers.
