Honest comparison
Courier is a multi-channel customer messaging platform whose send API is fire-and-forget by design. Pushary is a decision platform: enroll(externalId) connects a person's phone with one tap, and decisions.ask() holds your agent until that person answers, failing closed on silence.
The products overlap for about one second, the moment a message lands on a phone. After that they diverge. Courier's job is done at delivery, and everything it ships (journeys, preferences, inbox, provider routing) makes delivery better. An agent approval's job starts at delivery: hold the agent, collect the answer, enforce the timeout, keep the record. If you need the first job, Courier is a fine choice. If you need the second, you would be building it yourself on top.
Courier's automation nodes cover sending, delays, branches, batching, and digests, and none of them waits for a human response; the Delay node pauses for a duration or until a time. That is the correct design for messaging, and it means an agent cannot pause on a Courier primitive until a person decides. decisions.ask() exists for exactly that pause.
The assembled version uses action buttons pointing at your endpoint, automations for escalation, and your own database for who-approved-what. It works, and Courier has documented the pattern themselves. The bill arrives as pending-state storage, question-to-answer correlation, a timeout policy, restart recovery, and an audit story, each written and maintained by your team. That set is the product Pushary sells as two calls.
Courier pushes through the mobile app you ship, with the push credentials you manage. If you have that app, it is a fine path. If you do not, Pushary is the shortcut: the person taps one keyless link and their phone is connected, with native app push and PWA push notifications handled for you, keyed to your own externalId.
For customer messaging breadth, Courier is ahead and it is not close: 40+ providers behind one API, journeys, preferences, multi-tenancy, an embeddable inbox, and genuinely good agent operability of the platform itself through their MCP server and CLI. Pushary does not compete for that job. If your need is lifecycle and product messaging at scale, use Courier for it, and keep Pushary for the steps where a human must decide.

You can assemble one yourself, and Courier's own content has shown the pattern: send a message with action buttons that point at your endpoint, use automations for timed escalation, and record the answer in your own system. What their documented automation nodes do not include is a step that waits for a human response, and the Send API does not block on a reply. The pending state, the correlation, the fail-closed timeout, and the decision record are your build. Pushary packages exactly that loop as decisions.ask().
Yes, a substantial one, and it points the other way. Courier ships a hosted MCP server, a CLI, agent skills, and machine-readable docs so that AI agents can operate the messaging platform: send messages, manage templates, debug pipelines. That gives an agent sending power. It does not give the agent an approval gate on its own actions, which is the job Pushary does.
In Pushary, the decision resolves as not approved when your window closes, the agent is told, and the expiry is written to the ledger. Courier's docs do not document a deny-on-no-answer outcome; its Delay node pauses for a duration or until a time, so a timeout policy is something you compose from delays, status checks, and your own code.
Courier delivers push through your own mobile app with your own APNs, FCM, Expo, or OneSignal credentials, and SMS through your provider. Pushary provides the receiving side itself: one keyless tap connects the person's phone, and delivery uses native app push or PWA push notifications, with Slack as a routing option.
When the job is customer messaging: one API fanning out across email, SMS, push, in-app inbox, and chat providers, with journeys, preferences, and multi-tenant branding. Courier is built for that and has a real free tier to start on. Pushary is the right choice when an agent has to stop at a step, a specific person has to decide on their phone, and the outcome has to be enforced and recorded.
enroll(externalId) connects the phone. decisions.ask() blocks on the answer, fail-closed, with every outcome in a durable ledger. Works with the Vercel AI SDK, LangGraph, CrewAI, Mastra, the OpenAI Agents SDK, Eve, Hermes, and MCP.
