Eventarc
Google Cloud's Eventarc is a fully managed platform that enables developers to build event-driven architectures by routing events from various sources to supported destinations. It allows for the collection of events occurring within a system and publishes them to a specified destination, facilitating the creation of loosely coupled services that react to state changes. Eventarc supports events from Google Cloud services, custom applications, and third-party SaaS providers, providing flexibility in event-driven application design. Developers can create triggers to route events to various destinations, such as Cloud Run services, allowing for responsive and scalable application architectures. Eventarc ensures secure event delivery by integrating with Identity and Access Management (IAM), enabling fine-grained access control over event ingestion and processing.

Amazon EventBridge
Amazon EventBridge is a serverless event bus that makes it easy to connect applications together using data from your own applications, integrated Software-as-a-Service (SaaS) applications, and AWS services. EventBridge delivers a stream of real-time data from event sources, such as Zendesk, Datadog, or Pagerduty, and routes that data to targets like AWS Lambda. You can set up routing rules to determine where to send your data to build application architectures that react in real time to all of your data sources.
EventBridge makes it easy to build event-driven applications because it takes care of event ingestion and delivery, security, authorization, and error handling for you. As your applications become more interconnected through events, you need to spend more effort to find events and understand their structure in order to write code to react to those events.

Hooksbase
Hooksbase is event infrastructure for AI agents. It ingests events over four channels — HTTP webhooks, email, hosted forms, and scheduled cron — verifies and persists each one, then routes, transforms, and delivers to five typed outbound destinations: HTTP, AWS SQS, AWS EventBridge, GCP Pub/Sub, and S3-compatible storage. Delivery includes retries with exponential backoff, strict FIFO ordering, a dead-letter queue, and deterministic replay from persisted dispatch snapshots, so an agent can recover events it missed. Five verified provider packs (Stripe, GitHub, Clerk, Slack, Resend) validate signatures on ingest; outbound signing is Standard Webhooks-compatible with rotation overlap. Free starts at 5,000 deliveries/month with no card; Starter $25, Pro $79, and Business $249 add transforms, FIFO, and higher volume.

Gravitee
Gravitee is an AI agent management and API management platform designed to secure, observe, and govern interactions between AI agents, models, APIs, event streams, and enterprise services. Its AI Gateway provides centralized control for LLM traffic, MCP tool access, and agent-to-agent communication through LLM Proxy, MCP Proxy, and A2A Proxy capabilities. The platform can enforce authentication, authorization, least-privilege access, PII redaction, rate limits, spending controls, and audit logging across AI traffic. Gravitee also provides visibility into agent behavior, token consumption, dependencies, costs, and usage patterns so organizations can identify shadow AI and unmonitored workloads. Beyond AI governance, the platform manages APIs and event streams, including REST, GraphQL, gRPC, Kafka, and related enterprise integration patterns. Gravitee is designed for organizations that want a unified control layer for AI agents, APIs, events, and model access.
