To measure
ShakaPerf is our own ultimate perf-testing framework.
- Extremely easy to set up
- Statistically rigorous A/B testing
- Detects visual changes
- Stack agnostic
- Accessibility & SEO tests
- Automatic regression detection in the main branch
Lighthouse
Axe
Playwright
CircleCI
Docker
To optimize
We specialize in React & Rails apps, however our approach allows us to safely optimize literally anything.
React RSC
Ruby on Rails
Web Apps of All Stacks
A team of experts with tens of years of experience. We started as a regular Dev consulting company, and then gradually shifted to performance optimizations & OpenClaw-like AI solutions. We know everything about web performance.
We maintain widely used Open Source projects
- React on Rails — The only Ruby on Rails framework supporting React Server Components. With RSC we can make your React App extremely fast! Or if you aren't into full refactoring, we can just fix the most glaring performance issues.
- Shakapacker — Open Source Webpack/RSPack integration for Rails apps. Among other things we can help you reduce CI cost.
We have our own startup
HiChee — a price comparison search engine for vacation rentals.
ShakaCode far exceeded our expectations. Not only did they bring industry-leading technology - React on Rails PRO - to give us the performance and savings we needed, they also gave us the partner we were looking for. ShakaCode has provided the skills, experience, and professionalism we can depend upon as we grow our working relationship.
One of the things that had the biggest impact was the way ShakaCode managed the project. Everything was super-transparent, which, because we’re extremely cost-conscious, was important to us. Everyone tracks their time by the task. That made it easier to predict how long it would take and how much it would cost to develop new features.
We’ve reduced the time needed to bring new products to market—from a technical perspective—from weeks or months to just a few days, with cost savings of up to 90%. ShakaCode far exceeded our expectations, providing us with a platform on which we can grow our business.
Can't we just optimize ourselves?
Absolutely! And we will speed you up by setting up A/B tests and showing you all the knobs. Performance optimization can get very tedious, if you have to measure all the metrics manually. It's common to make a page faster on desktops and introduce a bug on mobiles. We will set up A/B tests for your most important UX routes on all screen types, so you won't need to rely on manual testing. This will also catch perf-regressions and visual changes in the main branch.
How fast will we see results?
We prioritize low-effort high-effect optimizations. So the most impressive stuff will be done in a couple of weeks. Once all low-hanging fruit is collected, the progress gets slower. We can squeeze every bit of performance out of your pages (months) or just do the basics (weeks).
We're not on React on Rails — can you still help?
Absolutely. While we built React on Rails and have deep expertise there, our performance optimization process works with any modern web stack — Next.js, Gatsby, Vue, Angular, Svelte and more. Web Vitals and Lighthouse scores are framework-agnostic, and so is our approach.
So you are using AI for optimization? Isn't it reckless?
Depends on how you do it. Just asking AI to make a page faster is risky. More often than not it will result in perf regressions and bugs. However our perf-testing framework discards 99% of buggy optimizations automatically, so AI has to keep trying to pass all the barriers. We carefully review everything to catch the remaining 1%.
