The record

Purpose: Coveralls analyzes test coverage to show which parts of code are not covered by tests.
Coverage dashboard: The dashboard summarizes projects' current coverage percentages and graphs changes over time.
Coverage detail: Repository pages show aggregate coverage down to sub-project, file, and individual code line.
Build history: Build history shows coverage changes for each build across branches, including pull requests.
Pull requests: Coveralls posts summarized coverage reports in pull requests and can send status updates that allow or block merges based on coverage criteria.
Notifications: Coverage change notifications can be sent to Slack or to webhooks.
Integrations: Coveralls says it works with any CI service and offers over 30 community-created integrations plus a GitHub Action and CircleCI Orb.
Source languages: The homepage lists integration packages for languages including C/C++, Go, Java, JavaScript, .NET, PHP, Python, Ruby, Scala, and others.
API: The API can add repositories programmatically and return statistics on recent builds.
Open source: Coveralls states that it is always free for open-source and public repositories.
Privacy and security: The cloud terms state that Coveralls reads code through the SCM OAuth token, does not store or cache private code, and accesses repositories on a read-only basis for coverage analysis.
Enterprise security: The Enterprise security page says its on-premises installation runs within the customer's existing security controls and can operate without outbound network access.
Data retention: The cloud terms specify detailed file coverage retention of 12 months for paid repositories and six months for public repositories, while aggregated build-level coverage is retained indefinitely.
Support: The pricing page offers a $200/month Support add-on with premium support, priority response, and live chat.
