    Mqtt Broker for 10 Years▲15

    Intended for 10-year (plus hopefully) deployment lifetime on $10-30 of silicon. The kind of thing you screw to a wall, plug in, and walk away from for a decade. No telemetry, no phone-home updates, no external dependencies. Storage decisions get a sanity checked against NVS wear... a write-per-PUBLISH would shred the flash in months, so the retained store and in tables that stay in PSRAM. Its heavily written with AI and borrowed a lot of visuals from Tasmota. Not for production use yet (been currently running it for a month with great results!)

    BlazeMQ – 52KB Kafka-compatible broker in C++20, zero dependencies▲5

    I built a message broker that speaks the Kafka wire protocol, so any Kafka client (librdkafka, kafka-python, kcat, etc.) works without code changes. The entire binary is 52KB. No JVM, no ZooKeeper, no third-party libraries — just C++20 with kqueue&#x2F;epoll. Starts in <10ms, uses 0% CPU when idle. I built this because running Kafka locally for development is painful — gigabytes of RAM, slow startup, ZooKeeper&#x2F;KRaft configuration. I just wanted something that accepts produce requests and gets out of the way. Technical details: - Single-threaded event loop (kqueue on macOS, epoll on…

    DuckDB for Kafka Stream Processing▲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:&#x2F;&#x2F;sql-flow.com&#x2F;docs&#x2F;category&#x2F;tutorials&#x2F; https:&#x2F;&#x2F;github.com&#x2F;turbolytics&#x2F;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&#x2F;or…

    AutoMQ 1.5.0 released, providing native Iceberg support for Kafka▲9

    AutoMQ is a fully open-source, next-generation Kafka built on top of S3. Version 1.5.0 is a very important release. In March of this year, Confluent officially launched the commercial capability of Tableflow. Now, with the AutoMQ open-source software, you can also experience this killer feature. Simply put, for Kafka streaming data, AutoMQ can automatically store it in S3 in Iceberg Table format, so you no longer need to manage Flink Jobs and Spark Jobs yourself to perform ETL operations and convert Kafka data into table format. We believe this will be the new paradigm for Kafka stream data…

    LavinMQ, an open-source message broker written in Crystal▲16

    Hi HN. I'm Carl, creator of LavinMQ. LavinMQ is an open-source message broker. AMQP 0-9-1, MQTT, HTTP and streaming. Single binary, minimal resource use. If you know RabbitMQ, it's that (but running on a fraction of hardware). We're the team behind CloudAMQP where we've hosted RabbitMQ for 14 years. Sometimes customers hit issues we couldn't fully explain &#x2F; work around. So we built our own broker, in order to provide solutions where we previously couldn't (which is much easier when you control the full stack). It all started by me building an open-source AMQP proxy to handle short-lived…

    MCP-Kafka – Natural Language Interface for Kafka Commands▲19

    I built a Model Context Protocol server that allows users to interact with Kafka using natural language instead of complex CLIs. It uses LLMs to interpret commands in plain English and executes the corresponding Kafka operations. This makes Kafka more accessible to non-experts while maintaining its powerful functionality.

    Confluent Kafka support added to FastStream v0.4.0rc0▲5

    FastStream - https:&#x2F;&#x2F;github.com&#x2F;airtai&#x2F;faststream, a stream processing framework, already supports Kafka stream processing using the aiokafka library, as well as other brokers such as Redis, RabbitMQ, and NATS. Responding to popular demand, the latest 0.4.0rc0 version introduces support for Kafka stream processing using Confluent Kafka's Python library - https:&#x2F;&#x2F;github.com&#x2F;confluentinc&#x2F;confluent-kafka-python.
