AI agent notification tools: phone alerts, replies and remote control

Compare Ntfyx, BotBell, AgentPager, anotifier, Remote Control and other tools for Claude Code and Codex. Official sources, reply paths, platforms, privacy and limits.

Updated 26 October 2026

Choose by what you need on your phone

For a whole Claude Code session, start with official Remote Control if your account is eligible. For Claude Code and Codex session access, evaluate Happy. For a completion alert, a terminal notification or ntfy completion hook may be enough. For permission decisions or questions, compare the supported workflow in Ntfyx, BotBell, AgentPager, Pushary and claude-remote-approver.

Your goal	Start here
Full conversation and continued instructions	Remote Control / Happy
Completion alert only	Terminal alert at the desk; ntfy hook for a phone
Approve a permission or answer a question	Ntfyx / BotBell / AgentPager / Pushary / claude-remote-approver
Claude Code, Codex and ordinary scripts together	Ntfyx CLI/MCP; HTTP hooks for alerts

Capabilities, requirements and starting prices

Permission approval authorizes a specific tool action. Answering a question supplies input to a waiting task. A completion notification reports an event. Check all three separately; a button, MCP support or encryption label does not establish the whole workflow. Sources and the verification date are attached to each row.

Ntfyx: one Inbox for scripts and agent replies

Ntfyx fits a workflow that sends command or script results and occasionally waits for a confirmation, choice or text answer. It keeps answers with the original question and can group task updates in a Session. It does not mirror an entire agent transcript or provide a remote shell.

Ordinary CLI and agent message titles, bodies, options and replies are end-to-end encrypted on your devices. The explicit fixed monitor-access and webhook-management questions and their signed phone answers are disclosed to the service for verification. HTTPS push and webhook requests are readable by the service before encrypted delivery. Optional provider verification secrets are encrypted and stored by the service, then used in plaintext to verify the raw webhook body; they are hosted secrets, not hidden from the service. My Monitor reads the monitored address, rule and response; a public publisher knows the content it publishes. The relay routes ciphertext and processes operational metadata such as identifiers, time, size and push tokens. Do not put secrets in monitored URLs or request examples. Independent security review is not complete.

Ntfyx native approvals: the verified boundary

Native permission hooks were verified on Linux x64 with Claude Code 2.1.283 / 2.1.284 and Codex 0.158.0, and on Apple silicon Mac with Claude Code 2.1.303 and Codex 0.163.0 (CLI 0.1.5+). Intel Mac native approvals remain unverified and return to the terminal. Codex requires interactive TUI and /hooks trust; codex exec does not trigger that approval flow.

Claude permission hooks are opt-in with --permissions on. Claude interactive terminal-choice precedence and terminal UI takeover have not been verified.

When another approach fits better

If you only use Claude Code and want its entire conversation on your phone, official Remote Control is a more direct fit than Ntfyx. Choose a full-session tool such as Happy when reading and steering sessions is the goal. For a simple one-way alert, a small ntfy hook can be sufficient. Ntfyx supports Windows CLI and local MCP.

If supported self-hosting, full-session control or arbitrary terminal input is required, choose a tool designed for that workflow. Native permission hooks have the separate platform limits above.

Continue with a setup guide

Choose the workflow first, then verify a harmless notification or question on your own devices before relying on it. The computer and waiting process must remain available for a phone answer to continue that task.
