Deploy with confidence.Execute with precision.
Version your entire deployment surface as typed Nickel in Git. Multi-tenant, with always-on mTLS between the control plane, execution servers, and agents, and point-in-time rollback — self-hosted, no phone-home.
- Self-hosted
- No phone-home
- Point-in-time rollback
Built to deploy reliably, not to lock you in
A self-contained alternative to legacy deployment tools — across bare metal and containers.
Config-as-Code
Define deployments as typed, versioned Nickel documents. Keep them in Git for bidirectional sync with a Git-authoritative mode — and a CLI converter for Octopus Deploy config-as-code exports.
Multi-tenant security
Tenant isolation enforced at the query layer. Fine-grained RBAC, OIDC single sign-on, and cryptographic audit trails.
Reliability at scale
A durable dispatch queue, horizontal execution servers, and automatic failover — with live 3D topology and streamed deployment progress.
Open Mantis and see what needs you
The dashboard opens on triage: targets that have gone quiet, deployments that failed, what is running right now, and which freezes are holding. Ordered by urgency, not by time, so the thing that needs a decision is at the top.
- Offline, stale and never-reported targets
- Failed deployments, most recent first
- In-flight deployments with live progress
- Active freezes and when they lift
Your deployments, version-controlled in Git
Define your deployment definitions as typed Nickel documents — actions (commands and scripts), sequences, solutions, environments, variables, schedules, and freezes. Keep them in Git and bidirectional sync reconciles Git and Mantis on a schedule or on a push webhook, with a Git-authoritative mode. A CLI converter turns an Octopus Deploy OCL export into Mantis Nickel documents for review.
- Actions as code — commands & scripts
- Sequences, solutions, environments, variables
- Bidirectional GitOps sync
- Octopus OCL → Nickel converter
Roll out, and watch it happen live
Deploy solutions, sequences, or individual actions across your fleet and watch progress stream live. One-click rollback, point-in-time recovery, promotions, and deployment freezes are all built in.
- Live streamed progress
- One-click rollback & point-in-time recovery
- Promotions across environments
- Deployment freezes with overrides
Resilient delivery that heals itself
A durable dispatch queue retries and ages out work while multiple execution servers share the load. Orphaned targets are reassigned automatically on failover — visualized in a 3D view of your control-plane topology.
- Durable, retrying dispatch queue
- Horizontal scale-out
- Automatic failover & reassignment
- 3D control-plane topology
The parts we deliberately left out
Nothing in the product counts targets, projects, tenants or users. There is no number to grow into.
No telemetry, no licence key, no kill switch. No usage figure ever leaves your network.
Every feature ships in the free tier. Paying changes your licence, not your software.
Source-available under BSL 1.1, converting to AGPLv3 on its Change Date. Read it, patch it, run it.
Free to self-host. Paid only when you are a company.
Every feature is included in both tiers — nothing is gated behind a licence. Commercial pricing is a flat annual fee banded by headcount, never per target, per node, or per user.
