Appcircle vs Highlight.io

Appcircle is a mobile DevOps platform that grew out of Smartface, a mobile development company with roots in Turkey; the two products for mobile CI/CD were announced in 2019. The legal entity is Appcircle Inc. in the US, while much of the engineering is in Istanbul. Its core job is automating how iOS and Android apps are built, signed, tested and shipped, including inside banks and other regulated enterprises.

The platform is split into modules: Build for iOS, Android, React Native and Flutter on Apple Silicon machines; Testing Distribution to send builds to testers by email, QR code or a portal; an Enterprise App Store for in-house apps without MDM; Publish to App Store, Google Play and Huawei AppGallery with approval gates; CodePush for over-the-air React Native updates; and Signing Identities for certificates and keystores. Appcircle AI diagnoses failed builds and offers an MCP server. A free Starter plan covers small projects, and the Corporate plan is quoted per module.

Appcircle fits enterprises that cannot send source code to a public cloud, since it can run on private cloud or fully self-hosted on Docker, Kubernetes or OpenShift with SSO and LDAP. Its named customers include Ziraat Teknoloji, Halkbank and Intertech. For small teams, Bitrise and Codemagic are better known, and Firebase App Distribution or Expo cover lighter testing and update needs at lower cost.

The free Starter plan includes 20 builds a month with 30-minute builds, 1,000 CodePush updates and 5 store publishes. Paid Corporate pricing is not public and is billed as an annual license.

Highlight.io is an open-source monitoring platform that combines session replay, frontend and backend error monitoring, logging and distributed tracing in one product. It was acquired in 2025 by feature flag vendor LaunchDarkly, which built its own observability product on Highlight's technology. The hosted Highlight.io service was retired at the end of February 2026 and customers were moved to LaunchDarkly Observability; the open-source code remains available for self-hosting.

The core workflow ties a user-facing problem to its root cause: a session replay shows what the user did, and the error that occurred is linked to the backend trace and to the logs emitted during that request. SDKs cover popular frontend frameworks and backend languages, and OpenTelemetry is supported for traces and logs. The code is open source and can still be self-hosted; while it ran, the hosted version offered a free tier with a monthly allowance of sessions, errors and logs and pay-as-you-go pricing above that.

Today Highlight mainly suits teams that want to self-host replay and errors in one tool and can maintain the code themselves, since the project no longer has an official hosted service or vendor roadmap. Teams that want the same approach as a managed product should evaluate LaunchDarkly Observability, especially if they already use LaunchDarkly. Sentry offers deeper error monitoring and its own session replay with a much larger community, LogRocket and PostHog are strong on product-side replay and analytics, and OpenReplay is another self-hostable open-source replay option.
