rqlite is a lightweight, open-source, fault-tolerant relational database built on SQLite and the Raft consensus protocol.
v10.5.0 is out now, and comes with an improved web console. Specifically the console features a new cluster topology view, allowing you to quickly understand the state of your cluster.
I continue to use both Claude and Codex for this type of development and both are working very well.

Versions 10.3.1 through 10.4.0 focus on four core themes: safeguarding cluster consistency under local fault conditions, overhauling how database backups stream over the network, improving the Change Data Capture (CDC) system, and tightening storage edge cases — partly with the aid of AI-assisted development and testing.

Antithesis has published a post on how they use AI Agents to inject bugs in rqlite, then check whether their tests catch them. Along the way their tests found three real bugs in rqlite, which I have since fixed.
rqlite is a lightweight, open-source, fault-tolerant relational database built on SQLite and Raft.
Version 10.3.0 has been released and includes some updates to the web console, upgraded SQLite, and other bug fixes and improvements. The headline fix in this release, however, comes courtesy of Antithesis.

I recently appeared on the Bug Bash podcast to talk about rqlite, software testing, and the impact of Agentic coding.

rqlite.io is the Hugo-based website for rqlite, built on the Docsy theme. It introduces people to the database, as well as serving all the technical documentation. Last month I decided to ask Claude Code to redesign the website.
OpenAI has given me six months of ChatGPT Pro through its Codex for Open Source programme, which backs maintainers of projects the wider ecosystem depends on. I will be putting it to work on rqlite — primarily coding and PR review, as well as the routine maintenance that keeps releases moving.
Many thanks to OpenAI for supporting the work.

After my initial experience with Fable, it got me thinking. I created rqlite, I maintain it. Why won’t Fable help me find and fix bugs in the software? Why does it refuse to identify potential bugs? Because it doesn’t know for sure I am who I say I am.
Today I tried Anthropic’s latest model, Fable, for the the first time. I asked it to run a full code review of the core Go code of rqlite.
Fable reject my first prompt as unsafe – review the rqlite code base for potential bugs – and Claude Code fell back to Opus 4.8.

Version 10.2.0 has been released with more improvements to the built-in web console and mutual TLS support.

It’s reached a new milestone this week – 1 million Docker downloads. Thanks to the entire rqlite community for their support and engagement with rqlite.

Version 10.1.0 has been released with improvements to the built-in web console. The web console now support directly examining the schema of your database tables, and basic schema management.
Today at Lowe’s I passed a Simbe robot doing inventory. A tall pole on a wheeled base, moving the aisles, looking at shelves. I was startled, but only because it appeared behind me. And then I felt nothing. No one else even looked up. The novelty collapsed immediately, because every part of it was already familiar.

rqlite
is a lightweight, open-source, fault-tolerant relational database built on SQLite and Raft. Version 10 is out now.
rqlite uses SQLite as its storage engine and has a particular relationship with the SQLite Write-Ahead Log (WAL). SQLite, left to itself, manages its own WAL: it checkpoints when the WAL grows, it checkpoints when the last connection closes, and it decides when frames move from the WAL into the main database file.
rqlite is a lightweight, user-friendly, open-source, distributed relational database. It’s written in Go, employs Raft for distributed consensus, and uses SQLite as its storage engine.
rqlite v10.0 has been released and introduces improved cluster and management features, including a new console application served by rqlite itself.
Be sure to download rqlite 10.0 and try it out today. Check out the docs and discussion is welcome on Slack.
It was great to present with Keith Chen on Google Cloud’s unified telemetry ingestion and routing solution at Google Cloud Next
Our new solution – comprising the Unified Management Plane and Telemetry Router – streamlines telemetry management for Google Cloud customers and developers. The design utilizes OpenTelemetry standards to ensure interoperability and avoid vendor lock-in. You can find the video here.

Antithesis is an autonomous software testing company that runs software inside a deterministic hypervisor, injecting faults and exploring edge cases that the usual testing cannot reach.

I will be speaking at the GCP Next next month in Las Vegas, NV. My colleague Keith Chen and I will present on GCP’s latest Telemetry management solutions, with OpenTelemetry at the center.

Last week I started using some of the new coding agents properly. Not in a careful, experimental way, but properly — for three days on rqlite. Claude Code. Copilot CLI. Tools I had yet to fully integrate into how I write software.

While working with Claude Code, I quickly needed it to operate on multiple versions of the rqlite codebase at the same time. Cloning the repository repeatedly would have worked, but it felt wasteful.
After many months of direct ChatGPT use, I’ve finally started coding with the help of Copilot and Claude Code. It’s definitely an intriguing experience. The biggest difference so far? I’m going to hit my Claude Code Pro limits pretty quickly, whereas my Copilot Premium Requests are far from exhausted.
I’ve been surprised by – and enjoy – one aspect of using large language models more than any other.
They often put into words things I have long understood, but could not write down clearly. When that happens, it feels less like learning something new and more like recognition. A kind of “ok, yeah” moment.

I sometimes read commentary about large software companies and notice a recurring pattern. People correctly identify real characteristics of large organizations, criticize them, but show little appreciation for why those characteristics exist in the first place.
