Dispatch vs Hookdeck Outpost

Dispatch receives webhooks, processes events, and delivers them to Discord, Slack, Telegram, or custom HTTP endpoints. It verifies incoming requests before storage, applies filters, formats payloads, and routes events to linked destinations. Filters can use header or body fields, and JSONata expressions can transform event data before formatting. Templates support Discord embeds, Slack Block Kit, and Telegram HTML with platform-specific variants. Failed deliveries can be retried with configurable exponential backoff, up to seven attempts by default. Documented source integrations include GitHub, GitLab, Bitbucket, Jira, Linear, OpenAI, Shopify, Stripe, and others; destinations also include Google Chat and Webex. Its CLI forwards webhook events through a secure tunnel to a local development server, with binaries for Linux, macOS, and Windows. Project-scoped API keys provide programmatic access. Dispatch says it encrypts destination URLs and tokens at rest and uses TLS 1.2 or higher for traffic. The cloud service has a free plan with 10,000 events per month and three days of history; paid plans start at $39/mo.

Hookdeck Outpost is outbound webhook infrastructure for platforms sending events to destinations selected by their users. Hookdeck offers a managed service, while the open-source version can run on infrastructure you manage. That version is licensed under Apache-2.0, written in Go, and distributed as a binary and Docker container. Outpost supports event topics, topic-based subscriptions, destination filters based on event content, tenant isolation, and fan-out to multiple destinations. Destinations include webhooks, AWS services, Google Pub/Sub, Azure Service Bus, RabbitMQ, Kafka, Cloudflare Queues, and Hookdeck Event Gateway. Delivery is at least once, so consumers should deduplicate events by event ID. Failed deliveries retry automatically with exponential backoff by default, with customizable schedules and manual retries through the Retry API, tenant portal, or Admin UI. It supports webhook signatures, Standard Webhooks compatibility, secret rotation, destination-failure alerts, optional automatic disabling of failed destinations, and OpenTelemetry metrics. Self-hosting is always free; managed Starter is $10 a month, and Growth is $499 a month.
