Where to be skeptical
4,362 open issues — maintenance capacity is a real concern
Low HN traction (18pt peak) — weak community signal
No formal release process found
44K npm downloads/wk — moderate, below Inngest and Trigger.dev
Editorial verdict
Best for developers who need quick MCP access to a massive API surface without building their own auth. For one-off API integrations via MCP (no workflow needed), Pipedream's free tier is the fastest path. 4,362 open issues raise maintenance capacity concerns.

Trigger.dev
92Background jobs platform for TypeScript developers. 14K stars, 258K npm weekly downloads (2nd in automation category). Highest HN peak in the category (745pts). Pivoting from 'open-source Zapier' to fully-managed AI agent workflows.

Windmill

Inngest
90Serverless workflow orchestration deeply integrated with the Vercel/Next.js ecosystem. 5K stars but 499K npm weekly downloads — highest in the entire automation category by 2x. Event-driven, step.ai.infer() API offloads LLM requests to Inngest infrastructure.

n8n
88179,860 GitHub stars — largest OSS repo in adjacent workflow-automation space by 2×. 3,000+ enterprise customers, ~200,000 active users, $60M Series B. 1,100+ ready-to-use integrations, native AI Agent node, MCP client/server support. Best for orchestrating SaaS integrations and processes with AI nodes — not for building agent systems in code.

Pipedream is an integration platform for developers.
Pipedream provides a free, hosted platform for connecting apps and developing event-driven automations. The platform has over 1,000 fully-integrated applications, so you can use pre-built components to quickly send messages to Slack, add a new row to Google Sheets, and more. You can also run any Node.js, Python, Golang, or Bash code when you need custom logic. Pipedream has demonstrated SOC 2 compliance and can provide a SOC 2 Type 2 report upon request (please email support@pipedream.com).

Key Features
- Workflows - Workflows run automations. Workflows are sequences of steps - pre-built actions or custom Node.js, Python, Golang, or Bash code - triggered by an event (HTTP request, timer, when a new row is added to a Google Sheets, and more).
- Event Sources - Sources trigger workflows. They emit events from services like GitHub, Slack, Airtable, RSS and more. When you want to run a workflow when an event happens in any third-party app, you're using an event source.
- Actions - Actions are pre-built code steps that you can use in a workflow to perform common operations across Pipedream's 1,000+ API integrations. For example, you can use actions to send email, add a row to a Google Sheet, and more.
- Custom code - Most integrations require custom logic. Code is often the best way to express that logic, so Pipedream allows you to run any Node.js, Python, Golang, or Bash code. You can import any package from the languages' package managers, connect to any Pipedream connected app, and more. Pipedream is "low-code" in the best way: you can use pre-built components when you're performing common actions, but you can write custom code when you need to.
- Destinations - Deliver events asynchronously to common destinations like Amazon S3, Snowflake, HTTP and email.
- Free - No fees for individual developers (see limits)

Workflows are sequences of linear steps triggered by an event (like an HTTP request, or when a new row is added to a Google sheet). You can quickly develop complex automations using workflows and connect to any of our 1,000+ integrated apps.
See our workflow quickstart to get started.
Event Sources
Event Sources watch for new data from services like GitHub, Slack, Airtable, RSS and more. When a source finds a new event, it emits it, triggering any linked workflows.
You can also consume events emitted by sources using Pipedream's REST API or a private, real-time SSE stream.
When a pre-built source doesn't exist for your use case, you can build your own. Here is the simplest event source: it exposes an HTTP endpoint you can send any request to, and prints the contents of the request when invoked:
export default {
name: "http",
version: "0.0.1",
props: {
http: "$.interface.http",
},
run(event) {
console.log(event); // event contains the method, payload, etc.
},
};

You can find the code for all pre-built sources in the components directory. If you find a bug or want to contribute a feature, see our contribution guide.
Actions
Actions are pre-built code steps that you can use in a workflow to perform common operations across Pipedream's 500+ API integrations. For example, you can use actions to send email, add a row to a Google Sheet, and more.
You can create your own actions, which you can re-use across workflows. You can also publish actions to the entire Pipedream community, making them available for anyone to use.
Here's an action that accepts a name as input and prints it to the workflow's logs:
export default {
name: "Action Demo",
description: "This is a demo action",
key: "action_demo",
version: "0.0.1",
type: "action",
props: {
name: {
type: "string",
label: "Name",
},
},
async run() {
return `hello ${this.name}!`;
},
};

Custom code
Most integrations require custom logic. Code is often the best way to express that logic, so Pipedream allows you to run custom code in a workflow using:
