Northflank vs Heroku: which platform fits your applications and team?

Northflank and Heroku both simplify application deployment but provide different infrastructure boundaries. Heroku centres on apps, dynos, buildpacks, and add-ons on Heroku infrastructure. Northflank abstracts Kubernetes across Northflank Cloud, your own cloud accounts, and eligible existing clusters.

This comparison covers target users, workloads, developer experience, previews, infrastructure, private networking, scaling, observability, security, Bring Your Own Cloud (BYOC), pricing, and operational responsibility.

• Heroku fits teams that want a fully managed app-and-dyno platform. Its dyno model, buildpacks, add-ons, Pipelines, Review Apps, and CLI suit web applications that can remain on Heroku-operated infrastructure. New buyers should note that Heroku stopped offering Enterprise Account contracts to new customers in February 2026, although self-service credit-card access remains available and existing Enterprise subscriptions can renew.
• Northflank fits enterprise and platform teams that need governed developer self-service with infrastructure choice. Its Kubernetes abstraction covers production full-stack applications, services, jobs, managed data, automated previews, autoscaling, volumes, and optional GPUs across Northflank Cloud, production BYOC, and eligible BYOK. Startups and individual engineers can use the same platform.
• Heroku exposes fewer infrastructure decisions. Northflank can expose cluster, node-pool, resource, networking, placement, and observability controls when platform teams need them, without requiring application developers to operate Kubernetes directly.
• Pricing follows different operating models. Heroku combines dyno, data-service, add-on, and, where applicable, Private Space or Enterprise charges. Review Apps incur normal resource charges. Northflank Cloud meters resources by the second without pay-as-you-go seat fees; Northflank BYOC combines platform fees with infrastructure billed directly by your cloud provider.

The table summarises the differences most likely to change a deployment-platform decision. Product and pricing details were checked on 27 August 2026.

Heroku serves developers and application teams deploying twelve-factor web applications, APIs, workers, and scheduled or one-off processes. Applications declare process types that run in independently scalable dynos, while Heroku data services and marketplace add-ons provide databases and supporting infrastructure.

Heroku spans Cedar and Fir. Cedar supports Common Runtime and Cedar Private Spaces. Fir is generally available through Fir Private Spaces and is implemented on Kubernetes and OCI/OpenTelemetry standards while retaining Heroku's dyno-facing model. Fir has not reached parity with Cedar across networking, autoscaling, Shield compliance, CI, and container-build features.

Heroku moved to a sustaining engineering model in February 2026, focused on stability, security, reliability, and support rather than new feature development. It also stopped offering Enterprise Account contracts to new customers. Existing Enterprise subscriptions and support contracts can renew, while new and existing customers paying by credit card can continue using Heroku without this contract.

Northflank gives developers self-service builds, deployments, databases, jobs, and environments while platform engineers govern access, networks, clusters, capacity, placement, and observability.

Northflank provides one control plane for production full-stack applications, services, jobs, managed data, automated previews, autoscaling, and optional GPU workloads. Enterprises, startups, and individual engineers use the same developer workflow.

Northflank Skills give compatible coding agents such as Codex, Claude Code, and Cursor Northflank-specific guidance for deploying, operating, and troubleshooting workloads through the API and CLI. Authentication, RBAC, and audit controls still govern what each agent can do.

Heroku standardises applications around dynos; Northflank standardises a broader Kubernetes-backed stack across managed and customer-controlled infrastructure.

Heroku's web, worker, and custom dynos handle continuous processes; one-off dynos handle maintenance, and Scheduler runs recurring commands. Dyno filesystems are ephemeral, so persistent data belongs in a backing service.

Northflank runs compatible container images as persistent services and workers, alongside one-off and scheduled jobs that can be started manually, through the API, or from a workflow. Managed addons cover databases, caches, queues, and object storage, while persistent volumes support custom stateful software.

On Northflank, teams can run these resources as one connected stack, apply private networking and shared secret groups, and use Northflank Workflows to coordinate releases, jobs, migrations, addons, and image promotion. Northflank also supports GPU-backed services and jobs on managed GPU plans or customer-cloud GPU nodes. Heroku does not currently offer GPU dynos.

Heroku builds a repository, reads commands from a Procfile, and runs them as dynos. Pipelines group environments and promote artifacts; configuration and add-ons remain per app.

Heroku's Container Registry and container stack and its heroku.yml Docker-build workflow are Cedar-only. Fir builds application images exclusively with Cloud Native Buildpacks.

Northflank provides Git-to-deploy with Dockerfiles, buildpacks, or external registry images. Builds and deployments can remain combined or separate.

Northflank Workflows coordinate multi-step releases, jobs, backups, and approvals. Templates define reusable application stacks, while GitOps keeps platform configuration synchronised with a Git repository. Teams can use the Northflank API and CLI to automate and manage these resources outside the dashboard.

Heroku runs dynos in Cedar Common Runtime, Cedar or Fir Private Spaces, and Cedar-only Shield Spaces. Cedar can peer with your AWS VPC, but dynos remain on Heroku infrastructure, so peering is not BYOC.

Northflank offers three models through one application control plane. Northflank Cloud is the managed option. With Bring Your Own Cloud (BYOC), Northflank provisions and manages a new Kubernetes cluster in your cloud account. With Bring Your Own Kubernetes (BYOK), Northflank connects an eligible existing cluster.

Northflank production BYOC, supported since 2019, covers AWS, GCP, Azure, Civo, Oracle Cloud, CoreWeave, and Nebius. Northflank BYOK can use eligible public-cloud, on-premises, or bare-metal Kubernetes, but requires a preferably dedicated cluster with compatible networking, storage, DNS, load balancing, and minimum capacity.

A Northflank BYOC or BYOK cluster requires at least 12 vCPU and 24 GB in total. Northflank BYOC supports a minimum of one node, while BYOK requires at least three nodes; each node must provide at least 4 vCPU and 8 GB of memory.

With Northflank BYOC, your organisation owns the account, bill, commitments, capacity, and cloud controls; Northflank manages the provisioned cluster and application platform.

Heroku Review Apps can be created automatically or manually from GitHub pull requests and require Pipelines plus GitHub integration. Eligible add-ons and dynos receive normal charges, and Fir lacks predictable Review App URLs.

Northflank Preview Blueprints automatically create multi-resource preview environments from pull requests or branch pushes, including frontend and backend services, databases, jobs, volumes, secrets, private networking, seed or restore workflows, and unique URLs. Configurable cleanup can remove previews when pull requests close or merge.

Heroku's Cedar and Fir Private Spaces provide isolated networking and stable outbound IPs. Internal routing, DNS service discovery, AWS VPC peering, IPSec VPN, and Shield Spaces remain Cedar-only.

Northflank provides private networking across workloads and data services, with isolated projects, cross-project ingress, network policies, secure external access, and BYOC VPC placement.

Heroku scales by dyno size and process-type count. Performance, Private, and Shield Cedar web dynos can autoscale using response-time and throughput behaviour; Fir autoscaling is not currently available.

Northflank lets teams set instance counts, choose CPU and memory, or autoscale deployments using CPU, memory, requests per second, or custom Prometheus metrics. BYOC adds custom resource plans, spot nodes, workload affinity, separate build capacity, node-pool scaling, and placement controls.

Heroku aggregates application, system, router, API, and eligible add-on runtime logs; build logs are separate. Cedar provides a bounded Logplex buffer, while Fir has no log history. Durable retention requires an add-on or drain.

Heroku application metrics are unavailable on Eco dynos. Basic dynos provide 24 hours of metrics at 10-minute resolution, while other eligible dyno tiers provide longer history and finer resolution. Heroku's Fir generation integrates OpenTelemetry and Telemetry Drains.

Northflank provides live and historical logs for builds, services, jobs, and addons, alongside resource metrics for monitoring workload performance. Teams can configure health checks and infrastructure alerts, review scoped activity through audit logs, and export logs to external systems using log sinks. In Northflank BYOC, the same control plane also provides visibility into clusters and node pools, connecting application-level signals with the infrastructure running those workloads.

Heroku centralises runtime operations. Northflank can extend the application control plane into customer-controlled cloud or Kubernetes infrastructure.

Heroku Enterprise provides accounts and teams, SSO, mandatory MFA, app permissions, Private Spaces, Cedar-only Shield controls, and monthly audit exports. Shield Spaces remain Cedar-only, and Heroku lists HIPAA compliance for Fir as forthcoming. Buyers should confirm the current compliance scope before using Fir for regulated workloads.

These capabilities do not mean a new Enterprise Account contract is available. Heroku stopped offering those contracts to new customers in February 2026; existing Enterprise subscriptions and support contracts remain supported and can renew. New buyers can still use Heroku through credit-card billing, but teams that require a negotiated enterprise contract should treat contract availability as a decision constraint.

Northflank provides granular RBAC, scoped API access, SAML or OIDC SSO, directory sync, MFA, secrets, network controls, workload identities, audit logs, and infrastructure events. Enterprise adds HA/DR, 24/7 support, SLAs, and customer-VPC, on-premises, forward-deployed, or air-gapped options.

Northflank is SOC 2 Type 2 and HIPAA compliant, with BAAs supported under Enterprise contracts.

Heroku fits vendor-operated infrastructure; Northflank fits governance spanning customer VPCs, Kubernetes, multi-cloud, or deeper controls.

Heroku combines dyno and data-service pricing with separate add-on and Private Space charges; Enterprise pricing applies to existing Enterprise contracts because Heroku no longer offers them to new customers. Northflank offers usage-based pricing for Northflank Cloud and custom Enterprise pricing that can include commitments, SLAs, 24/7 support, and onboarding. Northflank BYOC keeps infrastructure charges on your cloud-provider bill while adding Northflank platform fees.

• Heroku: There is no free dyno tier. Personal-account Eco costs $5 per month for a shared pool of 1,000 dyno hours and sleeps after 30 minutes of inactivity. Basic is prorated up to $7 per dyno monthly; Standard-1X up to $25. Data services, add-ons, CI, and Private or Shield resources add costs. Review Apps and one-off dynos consume normal resources. Heroku operates the runtime.
• Northflank Cloud: The free, always-on Sandbox includes two services, one database, and two cron jobs. Pay-as-you-go has no seat fees, meters resources by the second, and currently lists $0.01667 per vCPU-hour, $0.00833 per GB-hour, $0.15 per GB-month of SSD storage, and $0.06 per GB of egress. Enterprise pricing is custom and can include commitments, SLAs, 24/7 support, and onboarding.
• Northflank BYOC: Your cloud provider bills the underlying infrastructure directly, while Northflank currently charges $0.01389 per vCPU-hour, $0.00139 per GB-hour, and $0.00278 per GB of GPU VRAM-hour. Direct billing preserves applicable cloud credits, reservations, commitments, negotiated rates, and customer capacity choices. Include minimum cluster capacity and retained cloud-account responsibilities in the total cost.
• Total cost: Model workloads, data, builds, previews, transfer, support, cluster minimums, and engineering time. Northflank may reduce cost when granular allocation, spot capacity, or direct billing outweigh retained responsibility. For Heroku, include dyno, data-service, add-on, Private Space, and applicable contract charges in the total-cost calculation.

For a more detailed cost breakdown, see the Heroku pricing comparison and reduction guide, then validate the estimate against your current topology, usage, support requirements, and contract terms.

Heroku fits applications that map cleanly to its dyno model and vendor-operated runtime.

Heroku does not offer Enterprise Account contracts to new customers. New customers are limited to credit-card billing through the Heroku dashboard. Existing Enterprise subscriptions and support contracts remain honored and may renew as usual.

• Your stack maps cleanly to web, worker, one-off, and scheduled dyno processes.
• You value buildpacks, Procfile, Pipelines, Review Apps, and the Heroku CLI.
• The add-on marketplace covers your data and operational services.
• Heroku-operated Common Runtime or Private/Shield Spaces meet your networking, region, compliance, and data-boundary requirements.
• You prefer transferring runtime responsibility over controlling Kubernetes or cloud accounts.

Northflank fits enterprise and platform teams that need governed developer self-service across broader production workloads and infrastructure environments.

• You need one control plane for production full-stack applications, services, jobs, managed data, automated previews, autoscaling, volumes, and optional GPUs.
• You want Kubernetes abstraction without making developers operate Kubernetes.
• Production workloads must run in your AWS, GCP, Azure, or other supported cloud account, or on eligible public-cloud, on-premises, or bare-metal Kubernetes.
• Previews must reproduce private services, jobs, data, volumes, or seed workflows.
• You need multi-signal autoscaling plus node-pool, spot, affinity, or placement controls.
• Direct cloud-provider billing, existing commitments, specialised compute, or customer VPC data boundaries affect total cost and governance.

Heroku fits teams whose web applications, workers, scheduled tasks, and one-off processes map well to its app-and-dyno model and fully managed runtime. Northflank fits enterprise and platform teams needing governed developer self-service, Kubernetes abstraction, and one control plane for production full-stack applications, services, jobs, managed data, automated previews, autoscaling, workflows, volumes, and optional GPUs across Northflank Cloud, production multi-cloud BYOC, or eligible BYOK.

Heroku runs dyno process types on Heroku infrastructure. Northflank abstracts Kubernetes and runs connected stacks across Northflank Cloud, production BYOC, or eligible BYOK with deeper platform controls.

Heroku fits production applications within its dyno, add-on, networking, and infrastructure model. Northflank fits production applications requiring multi-resource stacks, Kubernetes abstraction, customer-cloud placement, GPUs, or granular controls.

Northflank fits enterprises and platform teams that need governed developer self-service while retaining control over clusters, node pools, resource plans, networking, scheduling, and deployment targets across production BYOC and eligible BYOK. Heroku operates the runtime without exposing Kubernetes-level infrastructure control. Heroku does not offer Enterprise Account contracts to new customers, while existing Enterprise subscriptions and support contracts may renew as usual.

Heroku runs dynos in Heroku-operated Common Runtime or Private Spaces. Cedar Private Spaces can peer with a customer-controlled AWS VPC, but that connectivity does not place the Heroku dynos inside the customer's cloud account, so it is not equivalent to Northflank BYOC.

Yes. Northflank BYOK connects eligible public-cloud, on-premises, or bare-metal clusters that meet its networking, storage, DNS, load-balancer, capacity, and component requirements. A new dedicated cluster is recommended.

Northflank automatically creates full-stack preview environments from pull requests or branch pushes, including services, databases, jobs, volumes, private networking, seed or restore workflows, and unique URLs. Heroku automatically or manually creates disposable Heroku apps for GitHub pull requests, with declared dynos and eligible add-ons billed as normal resources.

Northflank directly supports GPU services and jobs on Northflank Cloud and in BYOC GPU node pools. Heroku does not currently offer GPU dynos.

Northflank may reduce total cost when per-second allocation, no pay-as-you-go seat fees, spot capacity, or direct cloud billing outweigh cluster minimums and retained responsibility. For Heroku, include dyno, data-service, add-on, Private Space, and applicable contract charges. Compare the complete topology and retained engineering responsibility.
