No open ports detected: bind to 0.0.0.0 and PORT
A deployed web app usually shows "no open ports detected" because it listens only on localhost or ignores the port assigned by the host. Bind to 0.0.0.0 and read PORT from the environment.
Playwright out of memory: stop Chromium from crashing
Reduce Playwright concurrency first. Reuse one browser, close every context in a finally block, limit open pages, and increase container memory only after the process has a bounded workload.
Best Telegram bot hosting for polling and webhooks
The best host depends on how Telegram delivers updates to your bot. Long polling needs a process that stays awake, while webhooks need a reliable public HTTPS endpoint.
Cron job running at the wrong time: fix UTC and DST errors
A cron expression has no useful meaning until its timezone is known. Check the clock inside the running process, then pin an IANA timezone or schedule explicitly in UTC.
MCP server hosting: how to choose a production home
Remote MCP servers need HTTPS, Streamable HTTP, authentication, and a runtime that matches their state model. Here is how to choose between edge functions, managed containers, and a VPS.
What is a background worker?
A background worker is a process that takes slow or asynchronous work out of the user request path, usually by reading jobs from a queue.
You built it with AI. Now what?
The bit nobody vibe-codes for you is the deploy. Here is what actually happens between "it works on my machine" and something that stays running, in plain terms.
Your AI-built project keeps stopping. Here is why.
It runs, then it does not. Nine times out of ten it is one of four things, and none of them require understanding the code that broke.
How to host a Discord bot 24/7
Your app works until you close the laptop. Here is what actually keeps it online, what each option costs, and why the free tiers stop working after a few weeks.
Why your Discord app keeps going offline
It shows as online, then it does not. Here are the six causes in the order they actually happen, and how to tell them apart from the logs.
How Spocket works
What actually happens between saying "deploy this" and your app being online. No marketing, just the sequence.
Who Spocket is for (and who it is not)
An honest description of who gets value out of this, including the cases where you should use something else.
Deploying what Lovable, Replit or Bolt built you
These tools get you to a working app fast and then the hosting question arrives. What each one gives you, where it stops, and what to do when your project outgrows it.
Deploy an app straight from Claude or Cursor
You built the app in an AI editor. You can deploy it from the same window over MCP, without a CLI, a Dockerfile or an API key.
Security basics for things you vibe coded
AI writes code that works, not code that is safe by default. Five checks worth doing before anyone else can reach your project.
discord.py or discord.js: which to pick in 2026
Both are mature, both are maintained, and the answer is mostly about which language you already write. Here is the honest comparison, including where they genuinely differ.
Serverless or always-on: which does your project need
Functions and containers solve different problems. Picking the wrong one produces either surprising bills or an app that is asleep when it matters.
Environment variables for apps, done properly
Where the token goes, why .env does not get deployed, and how to stop a leaked secret from being a rewrite.
