Audience

Software teams that maintain their own API integrations: SaaS products, internal platform teams, and engineering groups carrying custom adapters against vendor APIs with no dedicated integration team.

About EchoRelay

EchoRelay is a managed runtime for custom API integrations.

Describe one integration once: what comes in, the target system, credentials, the retry policy, and how the answer maps back. EchoRelay validates each inbound request, maps it, replies synchronously, passes streams through, fans out to multiple targets, or queues delivery with automatic retry, a dead-letter queue and replay.

Every configuration change is versioned. Preview, diff, dry run, schedule, publish and roll back. When a vendor changes their API or rotates a credential, you update the configuration and publish. Deploy nothing.

Build and operate each integration through the REST API, an MCP server so an AI agent can do the wiring, or the web panel. Free to start, no card required.

Deposure
Deposure
Deposure is a secure, scalable API gateway that lets developers instantly publish their APIs without DevOps overhead, offering unlimited bandwidth with dynamic scaling to handle traffic peaks and ensure smooth performance for streaming, large data transfers, or millions of requests. It includes auto error handling with intelligent retry logic that detects failures, reroutes, or retries based on customizable rules, and surfaces real-time alerts and diagnostics to maintain a continuous user experience. It promises 99.97% uptime SLA backed by proactive monitoring, rapid incident response, and transparent reporting, so teams can focus on building while reliability is handled. With one-click connect, developers can expose local services securely in seconds via a CLI command without manual configuration or downtime, as a lightweight agent creates a secure tunnel instead of depending on traditional IP forwarding.

Hooksbase
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.

Hook0
Hook0
Hook0 is an open source Webhooks-as-a-Service platform that helps developers send, receive, manage, and monitor webhooks at scale. It is built for teams that need to add webhook support to their product without spending weeks building retry logic, signatures, monitoring, queues, dead letter handling, event logs, and subscriber management from scratch. With one API call, teams can publish outbound events, while Hook0 handles delivery infrastructure, configurable retry logic, webhook calls, endpoint monitoring, event persistence, and developer tooling. It keeps track of every event an application sends and every webhook call it makes, helping teams debug integrations, inspect delivery attempts, and maintain an audit log. Hook0 supports secure webhook delivery with HMAC signatures, key rotation, TLS encryption, and compliance-focused deployment options. As a fully open source platform, it allows teams to audit the codebase and self-host on their own infrastructure.

Shape requests for each target, then follow their delivery attempts in the request log.

Shape requests for each target, then follow their delivery attempts in the request log.

Shape requests for each target, then follow their delivery attempts in the request log. Each line is a versioned group of endpoints with its own base URL. Build the next version beside the one serving traffic, then activate it when it is ready. Set where a request goes, how it authenticates, and what happens when the target is down. Anything still undelivered lands in failed deliveries. A mapping is a tree of typed nodes. Edit it as JSON or build it visually. Both read back the same thing, so what an agent writes opens in the builder unchanged. Filter by request id, method, status or path. Open a row to see what each target answered. Deliveries that ran out of attempts wait here with the reason and the payload. Replay one, or all of them.
