BuildBuddy

BuildBuddy provides enterprise features for Bazel — the open source build system that allows you to build and test software 10x faster.

Incremental builds deserve an incremental cache. Major props to Tyler French from the @buildbuddy team for landing this change in @bazelbuild that reduces cache uploads and disk cache size by 40%+ https://t.co/kwFRLMpMew

Super cool work Tyler French + all the @buildbuddy + @bazelbuild people who manifested CDC https://t.co/9KxUAvGSpo

@steipete Happy to help! Codex team is already using BuildBuddy for this: https://t.co/e88DWHWi6f

[Steeve Morin @steeve]

I am using @bazelbuild to download a Zig nightly build

To then build the same Zig version from source (we have patches)

Using a custom LLVM source repo

Which is also built from source

And all of this using remote execution with @buildbuddy.

@siggi @buildbuddy Exactly ! I show everyone I can how I’m pretty much alone doing codex cloud at this scale just because I don’t care containers are only 2 cores. While every other agents wait minutes doing things locally, mine loop at light speed while everything compiles and test w/ @buildbuddy

[Siggi @siggi]

Your coding agent doesn't need a sandbox, it needs a remote execution cluster https://t.co/xRbLbi3WiH

Beyond excited to welcome @SmileyKeith to the BuildBuddy team! Keith is the maintainer of Bazel's iOS support, a contributor to LLVM and Swift, creator of the Mobile Native Foundation, and an all around awesome human.

Large engineering teams use Bazel to tame their ever-growing monorepos. Today, I'm excited to share rules_codex, a hermetic cross-platform Bazel toolchain and ruleset for OpenAI's Codex coding agent designed to make working in large enterprise codebases fun again.

[Siggi @siggi]

I've been building at the intersection of Bazel + coding agents for a few months and have some fun things to share. The first one is a hermetic, cross-platform Claude Code toolchain let's you easily use Claude in Bazel builds, tests, and runs. Link & more below!

@buildbuddy is hiring ops-minded engineers.
Closest known title is SRE.

Really the job is "offer world-best build perf & uptime while driving customer costs down using colocated hardware and the cloud."

Write me / @siggi / @tylerbw to learn more.

[Corentin Kérisit @corentinanjuna]

Endless thanks to @buildbuddy for the remote executors. Make sure you check it out! @sluongng FTW <3

Another great technical blog post by Maggie Lou on all the nitty gritty details of how we scale warm runners with snapshotting, chunking, cloning, and more. https://t.co/ZyJsxWfsRh

Bazel is a superpower.

@brankopetric00 We just moved from GitHub actions to bazel and buildbuddy, our build times went from 2.5hrs down to 6 minutes.
