AgentBell 4.0 brings agent messaging to your iPhone. • Agent Message API — any authorized agent or script can send real-time alerts directly to your phone • Unified Inbox — agent messages, approval requests, and activity history in one place • Smart Subscriptions — filter by source, topic, severity, and time window • Privacy-First Delivery — lock screen shows minimal detail by default; sensitive content stays in-app • Ordered Catch-Up — never miss a message, even offline or after a push delay • Severity Filtering — high and critical alerts require explicit opt-in • Badge Integration — unread agent messages count toward your app badge • Connector Kit — pair, send, and manage subscriptions from the agentbell CLI AgentBell is independently developed and is not affiliated with, endorsed by, sponsored by, or officially connected with Anthropic or OpenAI.

AgentBell 3.0 brings every bounded decision into one trusted Inbox. • Review requests from Claude Code, Codex, and supported connectors in one place • See the source, action, target, environment, risk, deadline, and approval outcome before you respond • Follow execution receipts separately from the human decision, including success, failure, or an unknown result • Manage connection health, access, revocation, and risk-aware notification preferences • Keep Activity summaries, Live Activities, and reliable catch-up for delayed notifications AgentBell remains deliberately bounded: no remote terminal, arbitrary prompts, agent takeover, batch approval, or automatic approval on failure or timeout.
