Sliplane vs. Heroku in 2026

Sliplane takes a different approach to container hosting. Instead of paying per dyno and per add-on, you rent a managed server and run as many containers as it can handle for one fixed monthly price.

Quick Comparison

Here's a quick overview of how the two platforms compare on a monthly basis.

How Sliplane Works

Here's the simple concept: You rent a server (starting at 1 vCPU / 1GB RAM for €9/month), and you can run as many containers as it can handle.

Want to host:

• A frontend app
• A backend API
• A PostgreSQL database
• An n8n automation workflow
• A Redis cache
• A monitoring service

All on one €9/month server? Go for it. Your cost stays the same whether you run 1 container or 20.

The Heroku Trade-off: Simple, But Costs Add Up

Heroku still has a polished developer experience, especially for teams already built around dynos, add-ons, and Salesforce. The trade-off is that every process type and managed dependency tends to become another line item.

The pricing structure:

• Eco dyno: $5/month, sleeps after 30 minutes of inactivity
• Basic dyno: $7/month, always on
• Standard dyno: $25-50/month per dyno
• Performance dynos: $250-500/month
• Postgres Essential starts at $5/month
• Key-Value Store starts at $3/month

Real costs:

• Running a simple web app 24/7: $25/month minimum
• Add a database: +$5/month for the smallest Essential Postgres plan
• Need Redis-compatible caching? +$3/month minimum, more for production tiers
• Want to run 3 apps? That's $75/month just for the dynos

Meanwhile, Heroku is still less natural for:

• Docker Compose natively
• Multi-container Docker stacks on one shared server
• Running arbitrary databases and tools next to your app
• Keeping a whole side-project stack on one fixed bill

One-Click Open Source Deployments

Both platforms let you deploy open source tools, but the experience is night and day:

Heroku:

• Limited marketplace with outdated "buttons"
• Each app needs its own dyno ($$$)
• Many Docker-first tools need adaptation to fit the dyno model
• Buildpacks are great for app code, less great for whole Docker stacks

Sliplane:

• Modern presets for popular tools (n8n, databases, AI tools)
• One-click deployment with zero additional cost
• Full Docker support - if it runs in Docker, it runs on Sliplane
• Deploy as many tools as your server can handle

Here is a demo showing how you can deploy n8n in less than 1 minute:

When Heroku (Still) Makes Sense

To be fair, Heroku isn't completely obsolete:

• Legacy Rails apps that were built specifically for Heroku
• Enterprise teams already locked into Salesforce ecosystem
• Projects where the add-on ecosystem saves more time than it costs
• Developers who want Heroku's mature deployment workflow

But in 2026, Heroku is rarely the cheapest way to run a multi-service Docker stack.

Real-World Example: Running a SaaS Application

Let's say you're building a typical SaaS that needs:

• A Next.js frontend
• A Node.js API
• A PostgreSQL database
• A Redis cache for sessions
• Background job processing with Bull
• Monitoring with Grafana

On Heroku:

• Frontend dyno: $25/month
• API dyno: $25/month
• Postgres: $5/month (smallest Essential plan)
• Key-Value Store: $3/month (smallest plan)
• Worker dyno: $25/month
• Monitoring: Not available (need external service)
• Total: $83/month minimum

On Sliplane:

• All services on one server
• Fixed monthly cost: €28.80 (Medium server)
• Including monitoring, logging, and metrics
• Total: €28.80/month (~$31)

The difference? Heroku is still convenient, but the per-dyno and add-on model gets expensive quickly once your app has multiple moving parts.

The Bottom Line

Heroku was revolutionary in 2010, and it is still a comfortable platform for many teams. But in 2026, its pricing model can feel heavy for small teams running several containers.

Sliplane gives you modern deployment tools, predictable pricing, and the freedom to run whatever you want - all for less than the cost of a single Heroku dyno.
