Why CircleCI?

Faster, more reliable build-test-deploy pipelines, intelligent design, and top-grade security are just a few of the features that make CircleCI a driving force for the world’s most innovative engineering teams.

Elite teams build here

From small startups to the largest G100 organizations on the planet, see why teams choose CircleCI to build fast, commit code with confidence, and gain a differentiating edge with smart automations.

Speed at scale

Through our thoughtfully-designed platform architecture and by giving developers powerful controls over their pipelines, we’re able to maximize build efficiency across projects and remove impediments to developers.

CI/CD built for performance:

  • Customizable RAM and CPU for different jobs
  • Workflows to help manage job orchestration
  • Parallelism to maximize build efficiency
  • SSH access into failed builds for easy debugging

“With CircleCI, things can move through the release process more quickly. It probably means an extra release a day.”

“The build process that used to take over 30m now takes less than half that. The team can run builds in parallel, removing bottlenecks.”

“Before switching to CircleCI, [the] team waited up to an hour to get through testing. With CircleCI they saw that wait time drop by 75%.”

“If your test suite takes an hour… your minimum incident resolution time can’t be faster than an hour. That’s [a] really strong motivator.”

Build and deploy with confidence

CircleCI simplifies the most complex parts of DevOps processes, letting engineering teams get to work doing what they’re best at—building great products. Fast feedback from CircleCI results in better decisions, better security, and higher throughput.

Trust your build process with:

  • Fast feedback on passing and failing builds
  • Workflow graph for easy visualization of build data
  • Orbs (reusable packages of config) for third-party integrations

“What makes me most confident in CircleCI is knowing that I have full control over the process, and this platform can scale with whatever my needs are.”

“Using CircleCI caused a marked jump in our confidence that we can merge our pull requests without breaking real Gatsby applications downstream.”

“Our users want new releases fast. We use CircleCI to test all of the touchpoints… and create scripts that fire tests automatically.”

Automation and intelligence for innovative teams

CircleCI lets teams build fully-automated pipelines, from testing to deployment, allowing them to focus on the real work of innovation. Using CircleCI, engineers can automate their entire testing suite for new commits, reducing the potential for human error, while using orbs to automate deploys.

Build smarter with:

  • Test metadata to help reveal flaky tests
  • Test splitting to increase build efficiency
  • Autoscaling to match customer demand
  • Orbs to help automate repeated processes across projects

Check out our intelligent features

“We made a small investment upfront; [now] our systems run automatically. That’s much better than deploying ourselves and making mistakes.”

“We don’t need to deploy an AWS machine. We can just write a script, add some config, specify that this needs to run once a month.”

The most secure CI/CD platform

CircleCI’s enterprise offering lets companies meet security and compliance needs by allowing them to install and manage CircleCI behind their firewall while offering other secure features like read/write access controlled via GitHub authentication. We are also SOC 2 Type II compliant and FedRAMP authorized.

Best-in-class security through:

  • Self-hosted solution
  • SOC 2 Type II certification
  • FedRAMP authorized
  • GovCloud partnership

Learn more about our security features

“Our code is our secret sauce. It’s nice knowing that it’s running on our own servers and network that we have full control over.”

“[We’ve] built a powerful system to automatically run security updates… engineers merge the PR, and builds run security updates on all servers.”

“CircleCI has enabled us… to move our CI infrastructure into a self-hosted VPC with AWS. This not only improves security… but cost as well.”

Build customer loyalty in minutes

Speed, scale, intelligence, automation, and security combine to create an ultra-responsive platform that helps companies quickly meet the demands of their customers.

Build and deploy new features quickly so your customers don’t miss a beat.

Start building great things for your customers now

“It’s common for customers to request a feature and we ship it within hours or days—sometimes within minutes. We can metaphorically hear jaws dropping on the other end of the support thread.”

“It used to be that pushing to production was a really big deal. By virtue of doing releases more frequently, it’s reduced that fear.”

“We [give] banks better back office systems. If someone asks for a loan and they get an answer in hours… [not] months, that’s a differentiator.”

“fastlane is built around continuous deployment. CircleCI enables us to… deliver the best value to our customers with total confidence.”
