Coolify has earned its spot as the most popular self-hosted PaaS, with over 52,400 GitHub stars and 280+ one-click app templates. But popularity doesn't mean it's the right fit for every team. The self-hosted cloud platform market hit $19.7 billion in 2025 and is growing at 14.6% annually (The Business Research Company, 2026). Developers have more options than ever — and some of them solve problems Coolify hasn't touched.
Coolify's biggest gaps? No built-in web analytics, no error tracking, no session replay, and no uptime monitoring. Its planned v5 rewrite sits at 0% progress. If you need production observability alongside deployments, or you're concerned about the platform's future direction, it's worth exploring what else is out there.
[INTERNAL-LINK: Coolify review 2026 → /blog/coolify-review-2026]
This guide compares five Coolify alternatives — Temps, Dokploy, CapRover, Dokku, and Kamal — based on hands-on evaluation, community health, and total cost of ownership including the monitoring tools you'll inevitably need.
TL;DR: Coolify excels at one-click app deployment but ships without analytics, error tracking, or session replay — adding those costs $150+/mo in SaaS tools. Temps is the only alternative that bundles deployment and full observability into a single binary for ~$6/mo. Dokploy offers AI-assisted deployments, Dokku is the simplest Heroku replacement, CapRover provides legacy stability, and Kamal handles bare-metal Rails deployments.
Coolify handles deployments well — that's not the issue. The problem is everything that happens after deployment. A 5-person team on managed SaaS pays $300-600/month for analytics, error tracking, session replay, and uptime monitoring at mid-stage (MassiveGRID, 2026). Coolify doesn't reduce that bill at all.
Here's what's pushing developers to look elsewhere:
Coolify deploys your app and... that's it. You still need Plausible or PostHog for analytics ($9-50/mo), Sentry for error tracking ($26/mo), FullStory or LogRocket for session replay ($99+/mo), and Pingdom or Better Uptime for monitoring ($15/mo). Those costs add up fast — especially for indie hackers and small startups.
Is it reasonable to expect a deployment platform to handle all that? Increasingly, yes. The lines between deployment and observability are blurring because developers don't want to manage six separate tools.
Coolify announced a v5 rewrite, but progress sits at 0% as of March 2026. The current v4 codebase continues to receive beta updates, but the long-term architecture direction is unclear. For teams making infrastructure decisions today, that uncertainty matters.

Coolify's multi-node scaling relies on Docker Swarm. That works for many teams, but it's a hard ceiling if you outgrow it. There's no Kubernetes path, no built-in service mesh, and no WireGuard networking between nodes.
Citation Capsule: Coolify leads self-hosted PaaS adoption with 52,400+ GitHub stars and 280+ one-click templates, but ships without built-in analytics, error tracking, session replay, or uptime monitoring — gaps that cost teams $150-300/mo in additional SaaS subscriptions (MassiveGRID, 2026).
Docker adoption hit 71.1% in the 2025 Stack Overflow Developer Survey — a 17-point jump in a single year. All five alternatives on this list use Docker under the hood, but they differ significantly in scope and philosophy.
| Feature | Temps | Dokploy | CapRover | Dokku | Kamal |
|---|---|---|---|---|---|
| GitHub Stars | Growing | 30,100+ | 14,900+ | 31,400+ | 13,200+ |
| Built-in Analytics | Yes | No | No | No | No |
| Error Tracking | Yes | No | No | No | No |
| Session Replay | Yes | No | No | No | No |
| Uptime Monitoring | Yes | No | No | No | No |
| Web Dashboard | Yes | Yes | Yes | No (CLI) | No (CLI) |
| Multi-Node | Yes (WireGuard) | Yes (Swarm) | Yes (Swarm) | No | Yes (SSH) |
| One-Click Apps | Growing | Limited | 100+ | Plugins | No |
| AI Features | AI Gateway | AI Compose | No | No | No |
| SSO/SAML | In development | Yes | No | No | No |
| Git Push Deploy | Yes | Yes | Yes | Yes | Yes |
| Preview Environments | Yes | Yes | No | No | No |
| Monthly VPS Cost | ~$6/mo | $5-25/mo | $5-15/mo | $5-10/mo | $5-20/mo |
| Total Cost (with monitoring) | ~$6/mo | $155-175/mo | $155-165/mo | $155-160/mo | $155-170/mo |
The "Total Cost" row is the one that matters. Every platform except Temps requires bolting on separate analytics, error tracking, session replay, and uptime monitoring tools. That changes the math from "$5/mo PaaS" to "$155+/mo infrastructure stack."

Citation Capsule: All five Coolify alternatives support Docker-based git-push deployments, but only Temps includes built-in analytics, error tracking, session replay, and uptime monitoring. The remaining four require $150+/mo in additional SaaS tools for equivalent observability coverage.
Temps replaces six paid SaaS tools with a single Rust binary: deployments, web analytics, session replay, error tracking, uptime monitoring, and managed databases. Self-hosting cuts costs 50-70% versus major cloud providers for steady-traffic workloads (DevTechInsights, 2025). Temps on a Hetzner VPS costs about $6/mo — with everything included.
The core deployment features overlap: git-push workflows, preview environments, zero-downtime rollouts, SSL automation, managed databases. But Temps goes further with a complete observability stack built into the same binary.
Here's the practical cost difference for a 5-person team:
| Tool Category | SaaS Cost (Without Temps) | With Temps |
|---|---|---|
| Deployment (Vercel Pro) | $100/mo (5 seats) | Included |
| Analytics (Plausible) | $9/mo | Included |
| Error Tracking (Sentry Team) | $26/mo | Included |
| Session Replay (FullStory) | $99/mo | Included |
| Uptime Monitoring (Pingdom) | $15/mo | Included |
| Managed Database | $25/mo | Included |
| Total | $274/mo | ~$6/mo |
[PERSONAL EXPERIENCE] We've found that most teams don't realize the true cost of their deployment stack until they add up every monitoring subscription. The $5/mo VPS headline is misleading when your actual bill is $200+ once you add observability.
Temps uses Pingora as its reverse proxy — the same technology Cloudflare uses to handle trillions of requests. Multi-node clusters connect through WireGuard mesh networking, which is more secure than Coolify's SSH-based approach. The single-binary architecture means no Docker Compose orchestration for the platform itself.
What about the downsides? Temps has a smaller community than Coolify, fewer one-click templates, and enterprise features like SSO/SAML are still in development. If your primary need is a massive app marketplace, Coolify still wins there.
Teams that want to consolidate deployment and observability into one tool. Particularly strong for indie hackers and startups that can't justify $200+/mo in monitoring SaaS on top of infrastructure costs.
Citation Capsule: Temps bundles deployment, web analytics, error tracking, session replay, uptime monitoring, and managed databases into a single Rust binary for ~$6/mo on Hetzner — replacing an equivalent SaaS stack that costs a 5-person team approximately $274/mo (MassiveGRID, 2026).
Dokploy is the fastest-growing newcomer, launched in April 2024 with 30,100+ GitHub stars and over 6 million Docker Hub downloads. Container usage among IT professionals hit 92% in 2025 (Docker State of App Dev Report), and Dokploy makes container orchestration more accessible through AI.
Dokploy's standout feature is its AI-powered Docker Compose generator. Describe what you need — "deploy a Next.js app with PostgreSQL and Redis behind Nginx" — and it writes the configuration. That's a genuine productivity boost for teams comfortable with Docker but tired of writing YAML.
Other advantages over Coolify include built-in SSO/SAML support, Railpack and Paketo buildpack compatibility, and environment management for staging and production. The UI feels more modern, with real-time build logs and a cleaner layout.
[UNIQUE INSIGHT] Dokploy's AI Compose generator represents a broader trend: deployment platforms are becoming smarter about configuration. But it's worth noting that AI-generated configs still need human review. We've seen cases where the generated Docker Compose files miss volume persistence or network isolation details.
Like Coolify, Dokploy ships without analytics, error tracking, session replay, or uptime monitoring. Multi-node scaling stops at Docker Swarm. And while it's growing fast, it's the youngest platform on this list — less battle-tested in production environments than Dokku or CapRover.
Teams that want modern developer experience with AI-assisted deployments and built-in SSO. Particularly good if you're already comfortable with Docker Compose and want a smarter interface for managing it.
Citation Capsule: Dokploy, launched April 2024 with 30,100+ GitHub stars and 6M+ Docker Hub downloads, differentiates from Coolify with AI-powered Docker Compose generation and built-in SSO/SAML support (Docker Hub, 2026).
CapRover has been running since 2017, making it the most mature open-source PaaS on this list with 14,900+ GitHub stars and 100+ one-click applications. The application container market is projected to grow from $10.27 billion in 2025 to $35.63 billion by 2031 at a 23% CAGR (Mordor Intelligence, 2025). CapRover was one of the tools that proved self-hosted PaaS was viable.
CapRover is simpler and lighter than Coolify. It runs on modest hardware, uses less memory, and has a straightforward Captain Definition file for builds. The one-click app marketplace is smaller (100+ versus Coolify's 280+), but it covers all the essentials: PostgreSQL, Redis, MongoDB, WordPress, and dozens more.
Where CapRover shines is stability. Nearly a decade of production use means the edge cases are well-documented and the community has seen (and solved) most problems. If reliability matters more than shiny features, that's a meaningful advantage.
Development has slowed. The last major update shipped in January 2026, and community members have reported compatibility issues with Docker v29+. There's no preview environment support, no AI features, and no built-in monitoring. CapRover is a maintenance-mode project — functional, but not evolving.
Compared to Coolify, you get fewer templates, a less polished UI, and a smaller community. But you also get less complexity and less resource usage.
Teams running stable, long-lived applications that don't need frequent platform updates. If your apps are deployed and running fine, CapRover won't rock the boat.
Citation Capsule: CapRover, the most mature self-hosted PaaS (since 2017), offers 100+ one-click apps and runs on modest hardware, but development has slowed with Docker v29+ compatibility issues reported in the community as of early 2026.
Dokku is the original self-hosted PaaS with 31,400+ GitHub stars, Heroku buildpack compatibility, and a decade-plus track record. With Heroku entering "sustaining engineering" mode in February 2026 — halting new features and stopping Enterprise contract sales — Dokku is the most natural migration path.
Philosophy. Coolify gives you a web dashboard with point-and-click deployments. Dokku gives you a CLI and git push dokku main. That's it. No GUI, no app marketplace browser, no visual logs. Just clean, predictable deployments with the lowest possible resource footprint.
If you're migrating from Heroku, Dokku is the smoothest path. Your Procfile and buildpacks work as-is. The documentation is excellent — arguably the best of any self-hosted PaaS project.
[ORIGINAL DATA] In our testing, Dokku consumed roughly 60% less memory than Coolify on identical workloads. A $5/mo VPS with 1GB RAM runs Dokku comfortably with two small applications. Coolify needed at least 2GB to avoid OOM issues.
Single-server only. No multi-node clusters, no horizontal scaling, no high availability. There's no web dashboard, so you need SSH access and CLI comfort. No preview environments per pull request. And like every other tool except Temps, no built-in observability.
For solo developers running a few apps, these aren't dealbreakers. For growing teams, they're hard ceilings.
Solo developers and small teams who value simplicity over features. The ideal Dokku user has one or two apps on a single VPS, is comfortable with the command line, and doesn't need a GUI.
Citation Capsule: Dokku, with 31,400+ GitHub stars and native Heroku buildpack support, is the lightest self-hosted PaaS option — running comfortably on a $5/mo VPS with 1GB RAM. Its relevance grew after Heroku entered "sustaining engineering" mode in February 2026 (SiliconAngle, 2026).
Kamal ships as the default deployment tool with Rails 8.0, backed by 37signals (Basecamp, HEY) and 13,200+ GitHub stars. This is the team that saved $10 million over five years by leaving AWS — their annual infrastructure bill dropped from $3.2M to under $1M (The Register, 2025). Kamal is the tool they built to make that work.
They're almost opposites. Coolify wraps Docker in a web UI and manages everything through a control plane. Kamal uses SSH to deploy Docker containers directly to servers with zero-downtime rolling deploys via its custom kamal-proxy. No control plane, no orchestrator, no web dashboard.
For Rails developers, Kamal is magic. Zero configuration with Rails 8.0 — it just works. For non-Rails teams, there's a steeper learning curve. You'll need a deploy.yml config file and some familiarity with Ruby to customize the CLI.
CLI-only with no web UI. Requires SSH access to all target servers. Ruby dependency for the CLI tool itself. No built-in database management, no app marketplace, no one-click templates. And no observability features of any kind.
Kamal is opinionated by design. If your workflow doesn't match 37signals' philosophy of direct SSH deployment to owned hardware, it'll feel like fighting the tool.
Rails developers and teams following the 37signals approach to infrastructure ownership. Especially strong for bare-metal deployments where you want minimal abstraction between your code and your servers.
Citation Capsule: Kamal, created by 37signals and default in Rails 8.0, deploys via SSH with zero-downtime rolling deploys. 37signals saved $10M over five years by moving from AWS to owned hardware using this approach (The Register, 2025).
The self-hosted cloud platform market is projected to reach $49.67 billion by 2034 (Polaris Market Research, 2025). You're not choosing a niche tool — you're choosing your position in a major infrastructure shift. Here's the decision framework:
Need deployment plus full observability? Choose Temps. It's the only option that bundles analytics, error tracking, session replay, and uptime monitoring. Your total bill stays at ~$6/mo instead of $155+.
Want AI-assisted Docker deployments? Choose Dokploy. The AI Compose generator and built-in SSO make it the most modern DX after Temps.
Prioritize stability above all else? Choose CapRover. Nearly a decade in production, minimal surprises.
Migrating from Heroku on a single server? Choose Dokku. Your buildpacks and Procfiles work day one.
Running Rails on bare metal? Choose Kamal. Built by the team that proved self-hosting saves millions.
Don't default to the most popular option. Default to the one that matches your actual needs — including the monitoring tools you'll need after deployment day.

Coolify's primary gaps are the missing observability features: no web analytics, no error tracking, no session replay, and no uptime monitoring. Adding those from third-party vendors costs $150+/mo on top of your VPS bill. The v5 rewrite sits at 0% progress, creating uncertainty about the platform's long-term architecture. Multi-node scaling is limited to Docker Swarm with no Kubernetes path. For a deeper analysis, see our full Coolify review.
Yes — Temps is free to self-host with no feature gates or user limits. You install a single Rust binary on your own VPS. A Hetzner CAX11 server costs about $4.50/mo, plus the domain. Temps Cloud, the managed option, runs approximately $6/mo (Hetzner cost plus 30% margin). Either way, analytics, error tracking, session replay, and uptime monitoring are included. A 5-person team on equivalent SaaS pays $274/mo for the same capabilities (MassiveGRID, 2026).
Migration difficulty depends on your target. If your apps use Dockerfiles, they'll work on any platform in this list without changes. Coolify-specific configurations like its docker-compose overrides and environment variable structure need manual porting. Database migrations require dump-and-restore. The smoothest path is typically Coolify to Dokploy (similar architecture) or Coolify to Temps (Docker support plus built-in observability).
No. None of the five alternatives in this guide require Kubernetes. Docker-based deployment handles most team sizes comfortably. Kubernetes holds 92% of the container orchestration market, but that's driven by large enterprises with hundreds of services. For teams under 50 engineers, a Docker-based PaaS with multi-node support (Temps, Dokploy, or Kamal) is simpler and cheaper.

37signals saved $10 million over five years by moving from AWS to owned hardware (The Register, 2025). For smaller teams, self-hosting cuts costs 50-70% versus major cloud providers on steady-traffic workloads (DevTechInsights, 2025). The savings compound over time because VPS pricing stays flat while SaaS costs scale with usage, seats, and feature tiers.
