Honest comparison
Svix is webhooks as a service: send, ingest and stream events between machines, with retries and signing. Pushary gets a decision from a person. Your agent calls decisions.ask(), your user answers on their phone, and your code gets the answer. If nobody answers in time, the action does not run.
The confusion usually starts with the word webhook. Both products list signed webhooks, so both show up in the same searches. In Svix, the webhook is the product. It carries events from one server to another, and the receiving server's status code is the outcome. In Pushary, the webhook is the last step: it tells your backend that a person approved, declined or replied. If your recipient is a server, you want Svix. If your recipient is a person whose answer the agent must wait for, you want Pushary.
Svix tracks a delivery: attempted, retried on a backoff schedule, then delivered or marked failed, with the receiving server's status code as the signal. Pushary settles a decision: approved, declined, answered, or expired, and expired counts as no. An agent guarding a refund needs the second kind, because a 200 from a server says nothing about consent.
Svix destinations are HTTP endpoints, queues, databases and storage. Its Slack-style connectors are documented as one-way transformations that capture no answer. Reaching a person's lock screen, collecting their choice and enforcing a time limit takes a different stack: connecting phones, push to the Pushary app and browser notifications, a store of pending requests, and a saved record.
Pushary's webhook is signed and fires when a person answers. It lands wherever your backend listens, which can be behind Svix Ingest with your other inbound events.
For webhooks, Svix is the standard: an MIT open-source core, mature retries and recovery tooling, an embeddable customer portal, ingestion with provider-specific verification, and event streaming. It has a real free tier and enterprise plans. Svix ships agent skills (github.com/svix/ai) and an MCP server that lets your customers debug their webhook deliveries. None of that is Pushary's job. If webhooks are your problem, use Svix for them.

Mostly no, and this page says so. Svix moves events between machines: your product sends webhooks to your customers' servers, with retries, signing and a portal. Pushary moves a decision between an agent and a person: the agent asks, a person answers on their phone, and the agent continues. Teams land here because both show up when you search for agent approval tools. So the honest answer is a map, and plenty of stacks run both.
Not out of the box. Svix delivers asynchronous webhooks, and the response signal is the receiving server's HTTP status code. Their docs show no approval feature, no blocking call and no way to capture a person's answer. You could build an approval system that uses Svix to deliver events to your own backend. You would still build the human side yourself: reaching the person, the wait, the timeout and the record.
Yes, a developer-tooling one. Svix ships agent skills (github.com/svix/ai) and an MCP server that lets your customers debug their webhook deliveries. That is useful, and it is different from an agent pausing for a person's decision, which is what Pushary does.
In your backend. Pushary handles the human decision, and when a person answers, a signed webhook can land in your backend, which can sit behind Svix Ingest. Machine events flow through Svix, human decisions flow through Pushary, and your backend joins them.
Whenever the job is webhooks: sending them to customers reliably at scale, ingesting and verifying third-party ones, or streaming events across company boundaries. It is open source at its core, mature and built for exactly that. Pick Pushary when the event is a question only a person can answer.
Connect your users' phones once with a link. Then ask before the risky step, and your code waits for the answer. No answer means no, and every answer is saved. Works with the Vercel AI SDK, LangGraph, CrewAI, Mastra, the OpenAI Agents SDK, Eve, Hermes and MCP.
