Lenses VS Code Plugin - multi-Kafka DevX & governance within the IDE

Engineering is in the middle of an almighty shift. Thanks to AI code-generation solutions, Engineers are being asked to take on a different and wider set of responsibilities in order to be more productive. It’s what’s increasingly being coined as Agentic Engineering - using AI agents to accelerate engineering & operations work while maintaining human oversight, quality and rigour.

Lenses MCP Server with OAuth 2.1

You can now drive Lenses from Cursor, VS Code, IBM Bob or Claude Code without running any extra piece of infrastructure locally. Lenses MCP offers secure tools across topics, schemas, Kafka Connect, SQL processors, consumer groups, datasets and pod logs: everything an engineer would normally click through in the Lenses UI, now reachable from any MCP-compatible client over HTTP.

Introducing Kafka Skills for AI Engineering Agents

If you've written a line of code in the last 18 months, you already know this. Tools like Claude, Codex, Bob, Kiro and Cursor have made agentic software engineering the default. Most developers today are writing prompts as much as they are writing code. That shift changes what ‘developer experience’ means. Clean UIs, useful tools and good docs are still the foundation but the focus has shifted to ensuring a coding agent actually knows what it is doing, in the hands of a developer.

Lenses 6.2 - Trusting Agents to build & operate event-driven applications

At Lenses, our goal has always been to help organizations get the most out of their streaming data. We started with visibility into the Apache Kafka, moving up to the part that drives value, the application layer and now the Agentic layer. Lenses 6 moved us into a multi-Kafka world, as increasing, our clients aren’t just running on one type of Kafka anymore, and as sovereign cloud becomes increasingly topical (no pun intended) this is only increasing.

Kafka Migrations Need More Than a Replicator

Jonas Best & Patrick Polster Kafka migrations are one of the riskiest infrastructure projects a platform team can take on. Miss a dependency and a downstream app starts reprocessing events it already handled leading to breaking SLAs and eroding trust with application teams. Migrate without visibility and you risk a major production issue. The instinct is to reach for a replication tool and call it done. But replication is only one piece of the puzzle.

Self-Service Data Replication with K2K - part 1

First in a 3-part series on self-service K2K replication. This post tackles how to give self-service access to deploy K2K without handing over the keys to your Kafka clusters. Lenses developed K2K (Kafka-to-Kafka) to solve two major problems: This includes making it as self-service as possible so developers can deploy without requiring a PhD in MirrorMaker2. One key design requirement: don’t force engineers to manage credentials to authenticate with Kafka.

The $11 Billion Question: What the acquisition of Confluent by IBM means

What’s remarkable is how long Confluent competed at the highest level. Creating a category and type of application is hard; transitioning to cloud and surviving against hyper scalers is even harder. That alone is a huge achievement. Some see this as a pressured exit. But another way to look at it is as a strategic purchase by IBM to strengthen its position in enterprise data movement and integration.

JSON schemas to control your Lenses & infrastructure provisioning

When we talk about JSON schema in the world of Kafka and streaming, you may assume the schema for the events/messages. But how many times have you fumbled in the configuration about trying to get an application deployed? Schemas that describe how to configure and deploy Applications or applications-as-code, are also important, allowing us to automate application landscapes. Especially as we will soon be a wash with catalogs for AI Agents, MCP servers etc.

Fat Fingers? Not With Our K2K Config Schema Protector!

Picture this: It's 3 AM. You’re on-duty in case there is an outage. A team in the other part of the world merged PR and released a new version of K2K Replicator and it crashed. Consumer group lag is spiking to the universe. You’re paged & woken up, went to your laptop, the team already reverted PR, things are stabilising, but what really happened, you have to investigate now as postmortem has to be done.
