Introducing FlowEngine Functions: Code That Bills by the Second

You wrote a small script. A webhook handler, a daily report, a Slack bot. You don't want to spin up a server for it. You don't want to learn five different cloud consoles. You want to push the file, hit a URL, and watch it work.

Today FlowEngine ships Functions: a place to deploy Node.js or Python code in one command, get a public URL, and pay only for the seconds it actually runs.

What It Does

Functions runs your code on managed infrastructure. You write a handler, push it, and FlowEngine hands you back a URL. Each request spins up an instance, returns a response, and shuts down. You pay per second of compute, not per request, not per month.

The pieces you would normally wire by hand are included:

• Public HTTPS endpoint: every function gets its own URL with TLS, ready for webhooks.
• Secrets: set OPENAI_API_KEY once in the portal, every function can read it.
• Live logs: structured request logs with status, latency, and your console.log output, streamed to the portal.
• Cron triggers: "run this at 8am Mondays" without a separate scheduler.
• Slack triggers: a function that fires when someone @mentions your bot.
• Templates: start from a working chromium scraper, a WhatsApp bot, or a scheduled morning brief in one click.

How to Deploy

Three ways, pick whichever fits your workflow.

From a local folder. Install the CLI, point it at your folder, ship.

npm i -g @flowengine.cloud/flowengine-cli
fe deploy

The CLI bundles your code, uploads it, and prints the live URL.

From the portal. Open flowengine.cloud, go to Functions, click New Function. Paste code into the inline editor, paste a GitHub repo URL, or drag a folder onto the upload area.

From a template. Browse the template gallery, fork one with a single click. FlowEngine clones the code into your account and pre-fills any secrets the template needs.

Pricing

Three tiers. Each one includes a monthly credit you can spend on compute.

Tier	Monthly fee	Included credit	Max memory	Max timeout
Free	$0	$10	512 MiB	15 seconds
Pro	$19	$19	8 GiB	15 minutes
Teams	$150	$50	32 GiB	60 minutes

Pricing past the included credit is per vCPU-second, per GiB-second, and per request, refreshed daily against the underlying cloud rates. No per-task minimums. No surprise invoke fees.

Why We Built It

FlowEngine already runs hosted n8n and OpenClaw for thousands of users. We kept hearing the same thing: "I have one small piece of glue code that doesn't fit a workflow. Where do I put it?"

n8n is great when the graph is the point. But sometimes you just want to write 30 lines of Python and forget about it. The answer used to be "rent a VPS, install your runtime, wire up a process manager, set up HTTPS, debug it for two hours." That is not a great answer.

Functions is the small-thing-shaped tool. Push code, get a URL, move on.

Try It

FlowEngine Functions is live now. The free tier is enough to run a personal webhook, a scheduled report, or a side-project API. Sign up free, no credit card required. Your first function can be deployed in under a minute.
