Daytona is one of the largest sandbox providers for AI agents, powering teams like LangChain and Writer. Every Daytona PR now follows one rule: no human review until every cubic comment is resolved. Full case study: cubic.dev/customers/daytona

Whatever @cubic_dev_ has been cooking, it's legit. 3 reviews in and I already got WAY more issues pointed out than with built-in Codex/Claude reviewing

local review is not only a great workflow win, but also great for #finops - find issues before they hit full CI! We use it for great benefit since it became available in #rsyslog. And it improves PR quality dramatically.

Unprompted, from a customer's internal Slack. You learn more from one message like this than from a hundred NPS responses.

I use @cubic_dev_ for a while now (both for open source project and proprietary one). Pretty efficient, we tested alongside Codex/Claude/Copilot reviews etc ... and this is a no match.

I use a stacked diff workflow, so small PR slices that stack on each other. Easier to setup a review process. This allows me to do quick manual reviews, and I also utilize @cubic_dev_ for automated reviews.

One thing that I love about @cubic_dev_ is the: "Prompt for AI agents" option where you can copy a prompt that is generated for you, copy/paste to your LLM of choice, so good

I just started using @cubic_dev_ when I first see your suggestion and man, same feeling over here it is so fast compare to bugbot, also I like the information and the dashboard

starting to love @cubic_dev_ more than cursor's bugbot every time I run PRs, cubic is just as good at literally half the time it takes for the review that's my biggest issue with bugbot - how extremely slow it is starting to believe this will never change because it's all-inclusive and using e.g. GPT 5.5 FAST variants would cost 2.5x more while we pay the same recommending cubic to most people now for speed

@withmartian jump in! There’s only 2 independent benchmarks for code reviews. One of the benchmarks is an online benchmark that measures performance live across tens of thousands of open source PRs. The other benchmark is an offline one, where the lab maintains a data set of ADPRs with known bugs and runs all the code review bots on them. @cubic_dev_ is first in both, by a huge margin

Then @cubic_dev_ Code Review goes through the code and tells the dev what needs fixing

Meu dia-a-dia, no momento, fica no @linear plugado no @conductor_build rodando Codex Pro 20x com Claude Code Max 20x. Comecei a usar o @cubic_dev_ para revisar as PRs no lugar do @coderabbitai. Mesclo os modelos por tarefa onde Codex acaba mais no front e revisor do Claude Code.

here is my AI coding stack april 2026 1. Cursor - v3 is the cleanest AI coder out there - super fast, best harness on the market - spending $1-2k/mo and worth every cent - 100% recommend if you can afford it 2. Codex - had a huge relaunch, now my #2 - $200 Pro plan is still insane value - computer use is NEXT LEVEL tech 3. Vercel Convex for web apps - nothing changed, still the best combo - Vercel for hosting, AI Gateway, analytics - Convex for db, backend, automations 4. Tauri Swift for desktop apps - still using Tauri/Rust for OpenUsage - played more with Swift (faster but harder) 5. GitHub Code Reviewers - you MUST use GitHub reviewers in 2026 - LOVE @cursor_ai's BugBot @cubic_dev_ - paired with my /shepherd skill = no-brainer 6. Frameworks - still Next.js Tailwind Shadcn - this stack never changes, it just works - don't get distracted by tinkerers biggest updates ⤵️ → still not using Claude Code 🤷🏻‍♂️ → dropped Conductor/Superset/other tools → started using @authkit over @clerk and I love it what are you building right now?

We've had an explosion of new users since announcing that cubic (YC X25) ranks #1 in AI code review benchmarks. Feedback is starting to trickle in. I think people like it.
