  • AWS us-east-1 outage: How Ablyโ€™s multi-region architecture held up
    During this weekโ€™s AWS us-east-1 outage, Ably maintained full service continuity with no customer impact. This was our multi-region architecture working exactly as designed; error rates were negligibly low and unchanged throughout. Any additional round trip latency was limited to 12ms, which is below the typical variance in any client-to-endpoint connection, and well below our 40โ€“50ms global median; this is... - Source: dev.to / 9 months ago
  • Real-Time Sync Alternatives: Vaultrice vs. localStorage, DIY, Firebase, Pusher
    Services like Pusher and Ably are experts in real-time messaging. They provide robust APIs for pub/sub channels, allowing you to broadcast events to clients reliably. - Source: dev.to / 11 months ago
  • CometChat Alternatives โ€“ Comparing the Top 10 Competitors

It's designed for developers building event-driven applications, including chat, but also supports broader use cases like live dashboards, GPS tracking, and collaborative tools. - Source: dev.to / about 1 year ago
  • Real-Time Authorization in a Chat Application with Permit.io and WebSockets
    For our web socket-based application, weโ€™ll be using Next.js and Ably, a service that allows us to easily integrate and manage real-time capabilities in our apps powered by web socket. - Source: dev.to / over 1 year ago

  • TalkJS Alternatives โ€“ Comparing the Top 7 Competitors
    TalkJS has carved out a niche in the chat API space by focusing on simplicity. Its ready-to-use UI and straightforward setup make it appealing for teams that want to add in-app messaging without sinking months into development. - Source: dev.to / 11 months ago
  • CometChat Alternatives โ€“ Comparing the Top 10 Competitors
    TalkJS is a chat API designed to help developers quickly add messaging features to web and mobile apps using a prebuilt UI and built-in notifications. It's tailored for platforms like marketplaces, education, hiring, and virtual events where chat is a feature, not the core product. - Source: dev.to / about 1 year ago
  • Cord didn't win. What now?
    My company, https://talkjs.com, is in the same market as Cord was. We let you put a full-featured chat UI inside your app; you control all the details and we handle the realtime infrastructure and scaling up. At the time we were rather surprised when suddenly, seemingly out of nowhere, Cord popped up as a direct competitor to our product. We were even more surprised to find out, only a few days later, that they... - Source: Hacker News / about 1 year ago
  • Web Components Are Okay
    I'm bullish on web components too. In fact, we're currently hard at work betting our entire company (https://talkjs.com) on it. I agree with Nolan here that performance is fine. People keep comparing web components to React or Solid components, but the latter inherently have a tiny granularity whereas web components is a way to distribute reuseable elements, not an application framework on its own.... - Source: Hacker News / almost 2 years ago
  • Stop Microsoft users sending 'reactions' to email by adding a postfix header
    To be frank I quite like this idea. Canโ€™t we standardize it somehow and add it to other email clients too? IMO the fallback, that internally itโ€™s just a regular, human-readable email, is quite neat (though I wonder how they dealt with other languages than English - do they know which language the email is in? Is it just always English? Thatโ€™d be bad). I work on a chat component library (https://talkjs.com) and we... - Source: Hacker News / about 2 years ago
