Sequin – A Kafka Alternative to REST APIs

Hey HN! We're Eric, Carter, and Anthony from Sequin (https://sequin.io). Sequin streams data from platforms like Stripe, AWS, and Salesforce into messaging systems like Kafka. Sequin loads historic data into topics and then streams new changes in real-time. You can provision a stream of API data with a single POST request. This means you can add third-party data to your apps and internal tools super fast. We support streaming to Kafka and NATS. If you don’t have a messaging system, you can use our serverless hosted one. To get your data at rest, you can stream to databases like…

    Sequin – Use Postgres/SQL to read from and write to APIs2023 · ▲7

    Hi HN community, I'm Anthony, co-founder of Sequin (sequin.io), and am excited to show you what we've been working on. Sequin lets you skip HTTP APIs and integrate with Postgres and SQL instead. While we originally launched with a one-way sync from APIs to Postgres, as of today, you can now _write back_ to APIs using `insert`, `update`, and `delete` on your synced tables. We built Sequin because no one is happy with HTTP APIs today. For developers that need to build on top of third-party APIs, each integration is bespoke. There are few standards. I've personally seen over a dozen different…

  • DuckDB for Kafka Stream ProcessingDec 2025 · sql-flow.com · ▲77

    Hello Everyone! We built SQLFlow as a lightweight stream processing engine. We leverage DuckDB as the stream processing engine, which gives SQLFlow the ability to process 10's of thousands of messages a second using ~250MiB of memory! DuckDB also supports a rich ecosystem of sinks and connectors! https://sql-flow.com/docs/category/tutorials/ https://github.com/turbolytics/sql-flow We were tired of running JVM's for simple stream processing, and also of bespoke one off stream processors I would love your feedback, criticisms and/or…

    Peerdb Streams – Simple, native Postgres change data capture2024 · ▲177

    Hello HN, I am Sai Srirampur, one of the Co-founders of PeerDB. (https://github.com/PeerDB-io/peerdb). We spent the past 7 months building a solid experience to replicate data from Postgres to data warehouses. Now we're expanding to queues. PeerDB Streams provides a simple and native way to replicate changes as they happen in Postgres to Queues (Kafka, Redpanda, Google PubSub, etc). We use Postgres logical decoding to enable Change Data Capture (CDC). Blog post here: https://blog.peerdb.io/peerdb-streams-simple-native-postgres.... 10-min quickstart here:…

  • Velvet – Store OpenAI requests in your own DB2024 · usevelvet.com · ▲109

    Hey HN! We’re Emma and Chris, founders of Velvet (https://www.usevelvet.com). Velvet proxies OpenAI calls and stores the requests and responses in your PostgreSQL database. That way, you can analyze logs with SQL (instead of a clunky UI). You can also set headers to add caching and metadata (for analysis). Backstory: We started by building some more general AI data tools (like a text-to-SQL editor). We were frustrated by the lack of basic LLM infrastructure, so ended up pivoting to focus on the tooling we wanted. So many existing apps, like Helicone, were hard to use as power…

    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…
