Keelport is the bug tracker, release planner, and App Store Connect command center for indie developers who ship apps in the Apple ecosystem. Built native in SwiftUI for iPhone, iPhone Duo, iPad, Mac, and Apple Vision Pro, Keelport syncs everything across your own devices through iCloud - no accounts, no servers, no subscriptions for a third party to host your roadmap. This is the tool you wish existed when you opened Xcode at 11 p.m. with a TestFlight crash report, a one-star review, and a feature request from a beta tester, and realized your bug tracker was a Notes file and your release plan was in your head. ==== What makes Keelport different ==== MCP INTEGRATION - BUILT IN, NOT BOLTED ON Keelport on Mac ships with a Model Context Protocol (MCP) server with 92 tools covering every part of your dev workflow. Point Claude, Cursor, Claude Code, or any MCP client at it and your AI assistant can file bugs, stage features for the next release, generate changelogs, query App Store reviews, reply to customer feedback, and convert TestFlight crashes into tracked bugs - all from your normal coding session. ONE SEARCH, IN YOUR OWN WORDS Search every project's bugs, features, releases, ideas, reviews and TestFlight feedback. Ask for "1-star reviews this week": Apple Intelligence reads it on device where available, and keywords work everywhere else. APP STORE CONNECT, IMPORTED AUTOMATICALLY Connect with a standard ASC API key and stop tab-juggling between dashboards. Keelport pulls in: Customer reviews: ratings, territory, developer responses, file a bug from any review Sales: daily units, proceeds, territory breakdown Analytics: impressions, page views, crash rate, conversion rate TestFlight beta feedback: screenshots and crash reports with one-tap conversion to bug or feature Performance metrics: launch time, hangs, memory, battery, per version and device Version submission history: every state from Waiting for Review to Ready for Sale Your API key is stored in the iOS Keychain and only ever sent to Apple's official api.appstoreconnect.apple.com endpoint. Never anywhere else. iCLOUD SYNC THAT JUST WORKS File a bug on your iPhone in line at the coffee shop. Fix it on your Mac an hour later - the bug is already there, marked staged for the next release. All powered by Apple's CloudKit through your own private iCloud database. The developer has zero access to your data. ==== Everything else ==== Projects, bugs, features, ideas, releases, comments and attachments Severity, priority, status, tags, platforms, effort estimates Checklists: repeating release steps, and which apps still need each item One-tap Markdown changelogs from staged items Markdown export of every project, for git or archive Widgets in every size: project status, release countdown, staged items, checklists, ratings, reviews, downloads Siri and Shortcuts: ask for your downloads, your rating, or your crash rate, or file a bug by voice Spotlight finds every project, bug, feature, release and idea Available in 11 languages Liquid Glass UI on iOS 26: clean native design down to iOS 18 ==== Privacy first, always ==== Keelport collects nothing. No analytics, no telemetry, no crash reporters, no tracking SDKs, no ads, no third-party data sharing. The developer operates no servers. Your data lives on your devices and in your own iCloud account, period. ==== Made by a working indie ==== Keelport is built by one indie developer who ships apps with these exact problems. Every feature exists because it was needed. Send feedback to solar59_meets@icloud.com - every message is read personally.
