Continuous Integration for your software
We use CircleCI for continuous integration and delivery of our mobile app. The main users are our DevOps team to help manage code releases. It's helped us push code to production with a standardize process and can now ensure we get a build with each merge. Our codebase is ReactNative and run on AWS CloudFront.

CircleCI Makes Automating Deploys Easy
We use CircleCI to deploy our app to various environments as well as run integration and E2E tests. This allows these processes to run independently from an individual machine.

CircleCI Review
We use CircleCI as an independent part of our continuous integration testing process, which handles both automated building and testing our software projects, as well as with our deployment pipelines to power constant delivery efforts. We use CircleCI because their environment is exceptionally customizable and generally reliable for our needs. There is also a generous free tier.

CI/CD for every developer and any organisation
We use CircleCI for most of our development workflows. Building, testing and deploying. We use it across most teams and departments.
It integrated nicely with GitHub and we are able to validate every change on every branch before merging and automatically deploying to production. I use it for both Ruby and React projects.

Circle CI the best on-cloud CI/CD system on cloud
At the moment, Circle is used across the company to make continuous integration and continuous delivery for the mobile native applications. Circle went to solve us the problem of have a dynamic and easy-to-use cloud-based continuous integration and delivery for mobile, without the maintenance cost of the resources and using only for the computing use.

Software engineering CI/CD pipelines done right!
CircleCI is being used as the main product for continuous integration, continuous delivery software development. It's being used primarily by release management/engineering and software engineering teams. It is solving the problem of needing to build a process around pushing code into production and following a schedule where code is continually deployed.

Continuous Integration - Simpler.
We've used CircleCI for the automation of build and test for smaller scale projects, in combination with another set of tools for continual deployment, hosting and visual testing. CircleCI is a great interface for viewing and managing automated jobs and workflows, and has made the process of CI more accessible for the team as a whole.
CircleCI is being used by my team as a continuous integration / continuous deployment pipeline for code and various other programmatic work. The business problems it addresses is the deployment, testing, and productionization of code supporting our main software engineering functions. Various other teams we work with also go along this pathway and use circle or other tools.
We use CircleCI to run our React tests as well as build and deploy our React code to AWS CloudFront on both staging and production.

Help your developers build/test/deploy code quick!
Our SaaS platform has gone to a CI/CD model, and CircleCI is a critical piece in automating the building, testing, and deployment of all non-production environments. Whenever a developer needs to test something, they can trigger a build and either recycle an older dev environment or launch a new dev environment that won't interfere with any other builds. This greatly accelerates the development process, and ensures the code won't have build errors or fail tests when it does get deployed to production.

CircleCI - Solid Continuous Integration Tool
We use CircleCI to allow for continuous integration across all of our software applications and environments. CircleCI allows us to build complex workflows, including steps to run pre-deploy / post-deploy scripts, execute test suites, and send slack notifications. With Circle, we can ensure code that is "broken" doesn't make it's way out, so we can be more confident that we are shipping bug-free code.

CircleCI is awesome
We're using CircleCI to run continuous integration for both front-end and back-end components for a SaaS application. It's linked to a popular source code repository which makes integration quite easy.
Overall, the experience has been fantastic. We're a small firm, and no need for the paid plan yet. But have successfully used the tool to bootstrap for the time being. The communities are quite helpful, even for those who don't have a paid plan for premium support. Would heartily recommend to colleagues.

Automation done right
In our company, we develop our financial product atop the Salesforce platform. We have extensive unit test coverage that is required by Salesforce to be able to list our product in their App store. To manage our software development process we needed a robust continuous integration and delivery solution. We used Atlassian Bamboo for several years before we made a push towards cloud integration using Circle CI. Circle CI is used for testing, building and packaging our code in the Github repo. It is used by our development department for continuous integration needs.

CI done right
In our Marketing firm when we started developing custom applications for our clients, we needed a robust continuous integration and delivery solution. We used Apache Jenkins for several years before we made a push towards cloud infrastructure. For that purpose we decided to use Circle CI for testing, building and packaging our code in the Github repository. It is used by our Software development department for continuous integration.

A great CI/CD alternative
Continuous integration and continuous delivery are two of our main pillars to deliver a successful experience to our end users. So CircleCI is a key piece in this chain for automating this process and flows from earlier development stages to QA, staging and production environments. [It is also used for] Maintaining our infrastructure and cluster health with cleaning and scale tasks.

Great CI Tool for Small Companies
Our Engineering team uses CircleCI to run tests on every commit to GitHub, and deploy to development and production environments depending on which branch the tests were run on. Standard use case for CI/CD. CircleCI integrates tightly with GitHub to run our tests, linter, etc. automatically for every pull request and every time we merge to development and master branches.

Frustrating UI but overall indispensable
We're an early-stage startup, and we use CircleCI to run automated tests in the cloud. In the early days, developers ran tests locally on their own development machines, but as the test suite grew, it simply took too much time. Running tests in the cloud lets us parallelize, so an hour's long test suite can run in minutes.
We use CircleCI for continuous integration and deployment at Troops. It builds all of our feature branches (PRs) as well as our major branches and automatically triggers deployments to both QA and production environments. We also run unit and integration tests as well as code coverage in CircleCI. It is primarily used by the Engineering team.
We use CircleCi as an integral to our continuous delivery pipeline across engineering. Using Circle allows us to focus on our application development. The concurrency of builds helps us split out our test suite across 15 different slices. Tight integration with GitHub allows us to easily integrate into pull request checks. While there are occasional hiccups there are way fewer problems than any other CI tool we've used in the past and we've used several different ones. Support is also pretty responsive and it's apparent that Circle is continuing to improve their product.
CircleCI is being used by our organization for continual integration and automated deployment of Drupal and WordPress websites to Pantheon, among many other smaller CI jobs. It is used entirely by our Development and DevOps team members. It allows us to commit a simple config file to Git that controls the way that our software gets deployed, making the tedious job of deploying changes for hundreds of websites regularly much simpler.

Testing FTW!
We're using CircleCI to run our suite of unit tests for a few projects (we handle end-to-end testing separately). We love that it auto-runs tests on git commits, runs our tests in parallel containers, and is configured with a simple YAML file. The UX is super clean and easy to debug when things go wrong. We're part of their beta program and they have some great features coming down the product pipeline that addresses our few headaches like their lack of support for "docker exec" (you have to use lxc-attach) and old Ubuntu containers.
We use this product every day and we're pretty happy with it.

One of the best CI tools available
[It is being used for] running the test suite on each commit and deploying different versions.

A fantastic CI solution for agile teams
We initially implemented it for automated testing of all our private repositories, and have been overall very happy with it. We looked at using it for our open source projects, but due to the fact that it doesn't support build matrices, we ended up going with Travis CI for public projects.

CircleCI makes our deployments easy
We're a software as a service (SaaS) business. We're using CircleCI in our development team. Every time we push a change to GitHub it runs our unit tests and if the push was to our staging or production branches, CircleCI triggers a deployment to that environment. If the tests fail I'm sent an e-mail and the deployments only get triggered if the tests pass.
January 12, 2017
Fast and Easy CI
I use Circle CI for continuous integration and delivery. It runs all of the tests and builds before our code ever sees production. It also notifies GitHub before we merge the code. I also utilize the use of Docker which Circle CI supports fully and makes running clean builds easier.
