Slipway vs Octopus Deploy
Octopus Deploy set the standard for release management: projects, environments, lifecycles, channels, tenants and runbooks. Slipway adopts that model and adds first-class pipelines (CI) so you do not need a separate build tool.
Where they overlap
Section titled “Where they overlap”Releases as immutable snapshots, lifecycles and channels, environment-scoped variables with precedence, approvals and manual interventions, runbooks, deployment targets reached by an agent or from a worker, and an audit trail.
Differences that matter
Section titled “Differences that matter”| Topic | Octopus | Slipway |
|---|---|---|
| CI | Build with another tool (Jenkins, GitHub Actions, TeamCity…) and push packages and releases into Octopus | Pipelines are built in; a pipeline’s output is a release. You can still use another CI tool and create releases from it |
| Pricing | Licensed by targets and instances; costs climb with scale | Per organisation, flat, unlimited users, no per-target tax |
| Agents | Tentacles, licensed by target | Runners, unlimited and free |
| Strategies | Rolling, blue/green and canary via step patterns and scripts | Recreate, rolling, blue/green, canary and progressive as built-in strategies with metric verification and automatic rollback |
| Metric verification | Not built in | Canary verification against Prometheus, Datadog, New Relic, CloudWatch, Google Cloud Monitoring |
| Self-host | Yes, paid | Yes, free (source-available) |
| Deploy steps | A large step template library, script-centric | Strategy engine with deployers (Kubernetes, Helm, Kustomize, ECS, Lambda, Cloud Run, Azure, VM, Terraform, script); steps in pipelines and runbooks use pipeline syntax |
| Windows and .NET legacy targets | Long history of IIS, Windows services and SSH targets | Via shell runners and script deployers; not the primary focus |
Concept mapping
Section titled “Concept mapping”| Octopus | Slipway |
|---|---|
| Space | Organisation |
| Project | Project plus Service |
| Environment | Environment |
| Lifecycle (phases) | Lifecycle (phases with auto_promote, min_soak) |
| Channel | Channel (version rules to lifecycle) |
| Release | Release (immutable) |
| Deployment | Deployment |
| Deployment target / Worker / Tentacle | Infrastructure on an environment; Runner in a pool |
| Target roles | Runner labels and Infrastructure |
| Variables with scoping | Variables with scoping (infrastructure, tenant, environment, channel, service) |
| Tenants | Tenant dimension on variables |
| Manual intervention | Manual gate / approval |
| Runbook | Runbook |
| Variable sets | Org and project-level variables |
| Deployment freeze | Freeze periods and calendar |
Step-by-step: Migrate from Octopus.
Choose Octopus when
Section titled “Choose Octopus when”You have a large existing Octopus estate, rely on its extensive step template library, or have many Windows and legacy targets and a team deeply invested in its model.
Choose Slipway when
Section titled “Choose Slipway when”You want the same release model without per-target costs, with built-in pipelines and canary verification, and the option to self-host for free.
