Easy in-app and email notifications for your web app

In plain words

Notifly is a notification service that enables developers to add in-app and email notifications to web applications. Launched in 2020, it provides a straightforward way to manage user communications without building notification systems from scratch. The product is designed for web developers and teams who need to implement notifications quickly. It handles both in-app alerts and email delivery, making it useful for apps that require multi-channel user engagement.

From the sources

Notifly is hosted notification infrastructure for product teams — one API for email, SMS, push, in-app, and chat. Visual workflow editor, AI agents, and the team features other platforms reserve for their enterprise tier. Define a notification once. Notifly routes it to email, SMS, push, in-app inbox, and chat — with localization, throttling, and per-user channel preferences baked in. The Notifly digest engine collects related events over a window — 5 minutes, an hour, a day — and ships one rich notification instead of fifty. Users stay, retention follows. Notifly runs the delivery pipeline — queues, retries, digests, websockets — so the only thing your service owns is the trigger. The API,…from notifly.io

  We as developers, build and maintain many services in code, one of them being notification service. In the last 5-7 years, API-to-user communications have exploded across SMS, email, chat apps, mobile, and web push. As a consequence, notification service handling them has become quite complex. Developers spend time building integrations with multiple providers, create templates for each channel, managing scheduling and routing based on preferences, maintaining queues to deliver notifications on time while managing scale. Besides, product teams have poor visibility on notifications as…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  https://github.com/OlexG/finclaw ^ repo if anyone wants to contribute. I realized that sometimes I'm pretty good at making random guesses about the future. (I.E, I think OpenAI will beat Anthropic in the short term, etc...) However, I'm bad at converting these guesses into actual market plays I can profit from. As such, I wanted to make a tool that connects to the right APIs and launches a swarm of agent experts to generate related plays based on your prediction. The very first super shitty V0 MPV just has Polymarket/Kalshi bets, but I will be adding a more complex…
