CapRover: Self-Hosted PaaS with Docker Swarm, Nginx, and Persistent Apps
CapRover wraps Docker Swarm, Nginx, and captain-definition in a simpler PaaS; stateless apps scale, while local persistent apps remain pinned to one node.

20 postsCoolify: Control Planes, Docker Servers, and the Self-Hosted PaaS Boundary
Coolify controls Docker, proxies, and resources on your servers over SSH; deployment gets easier, but OS, security, capacity, data backup, and recovery remain yours.
DigitalOcean App Platform: Managing PaaS Topology with Components and App Specs
DigitalOcean App Platform composes Services, Workers, Jobs, Static Sites, and Functions into an App, with an App Spec as the reviewable deployment contract.
Dokku: Turning One Docker Host into a Git-Push PaaS
Dokku combines a Git receiver, buildpacks or Dockerfiles, process models, Nginx, and plugins for a single-host Heroku workflow; simplicity comes from narrow orchestration scope.
Dokploy: Self-Hosted PaaS with Applications, Compose, Remote Servers, and Swarm
Dokploy supports single-container Applications and Compose or Stack, while treating one host, independent remote servers, and a Swarm cluster as distinct topologies.
Fly.io: The Real Boundaries of Machines, Fly Proxy, and Multi-Region Deployment
Fly.io places fast-starting Machines in chosen regions and connects them through Fly Proxy and private 6PN; cross-region state consistency remains your hard problem.
Kamal: Docker Deployment Without a Resident Control Plane
Kamal deploys immutable images from an operator over SSH and switches traffic through kamal-proxy; it is not a scheduler and does not operate hosts or data.
Koyeb: A Global Serverless Model of Apps, Services, and Instances
Koyeb groups Services in Apps, runs revisions as Instances in selected regions, and integrates global routing, autoscaling, private discovery, and CPU or GPU compute.
Kubernetes: Container Orchestration from Pods and Controllers to Declarative Reconciliation
Kubernetes is fundamentally API objects, controllers, and reconciliation loops—not YAML; it manages workload lifecycles without solving application state, data consistency, or organizational governance.
Pulumi: Infrastructure as Code in TypeScript, Python, Go, and Other Languages
Pulumi lets general-purpose programs register cloud resources for a deployment engine, providers, and stack state to preview and update; greater language power demands stronger abstraction discipline.
Railway: Deploying an Application Topology with Projects, Services, and Environments
Railway is not merely one-click deployment; it puts container services, environments, variables, and private networking into one operable application project.
Render: A Full PaaS Topology of Web, Private, Worker, and Cron Services
Render's value exceeds turning a repository into a URL: distinct service types model public HTTP, private listeners, queue workers, cron, data stores, and Blueprint infrastructure.
Renovate: Turning Dependency Updates into a Governed Continuous Process
Renovate is more than an update-PR bot: packageRules, grouping, schedules, minimum release age, and automerge policy determine update speed, review noise, and supply-chain exposure.
Terraform: The IaC Workflow of Providers, Plans, Applies, and State
Terraform compares provider schemas, configuration, state, and real APIs to create a plan and apply it; controlled state and change workflow matter more than HCL itself.
Where AI Code Review Stands Now: Lessons from Cloudflare's Multi-Agent System
Cloudflare ran a Multi-Agent Code Review system internally for 30 days — 131K reviews, median 3 minutes. This post breaks down their architecture and compares it with solutions from Anthropic, GitHub, CodeRabbit, Greptile, and others.
Docker in Practice: Containerizing from Development to Deployment
Docker lets you bundle your application together with its environment, eliminating the 'works on my machine' problem. Combined with multi-stage builds and Compose, it's an essential tool for modern backend deployment.
GitHub Actions: A CI/CD Primer and Monorepo Strategy
GitHub Actions is the lowest-friction CI/CD tool available today, ideal for small-to-medium projects. The key to monorepos is using path filters so only affected apps trigger a build.
docker restart Does Not Re-apply Volumes — Debugging a Bind Mount Failure
docker restart does not recreate the container, so changes to volumes in docker-compose.yml only take effect after running docker-compose down && up.
Managing Multi-Service Reverse Proxy with nginx conf.d: A Daodao Case Study
A monolithic nginx.conf becomes unwieldy as services grow. Splitting it into per-service files under conf.d/ via include is the standard solution.
Cloudflare Free Plan Maintenance Page: Custom Error Pages Unavailable, Use a Worker Instead
Cloudflare Custom Error Pages require a paid plan. On the Free Plan, use a Worker with inline HTML to intercept 5xx responses instead.
