Dokku vs Robusta: at a glance
What is Dokku?
Dokku is quietly turning into a k3s front-end with a JSON-first CLI.
Dokku is twenty-six patches deep into the 0.38 line, shipping small releases every one to two weeks whose bodies are largely dependabot bumps. The substantive work sits in two places: the k3s scheduler, which just picked up wildcard domain routing through Traefik, manually managed cert issuers, and kernel sysctl control, and the CLI surface, where `:report` and `:list` subcommands are gaining `--format json` while being ported from bash to Go. A command-injection fix in the docker-options eval path landed in v0.38.25.
What is Robusta?
Robusta's alpha train keeps widening what can push alerts in and where it can run.
Robusta ships alpha releases every one to three weeks, each a small bundle of merged PRs rather than a headline feature. The recent four cover alert ingestion breadth (Jira Service Management, F5 Distributed Cloud documented against the Send Events API), operational plumbing (JSON log format behind an environment variable, a global imagePullSecret for the Helm chart, namespace-scoped RBAC guidance), and routine dependency and CVE bumps. The 0.47.0 release adds a workflow trigger action, letting one Robusta workflow fire another on the platform.

Dokku
5.0INFRA · APIS
Dokku is quietly turning into a k3s front-end with a JSON-first CLI.
◆ Current state
Dokku is twenty-six patches deep into the 0.38 line, shipping small releases every one to two weeks whose bodies are largely dependabot bumps. The substantive work sits in two places: the k3s scheduler, which just picked up wildcard domain routing through Traefik, manually managed cert issuers, and kernel sysctl control, and the CLI surface, where `:report` and `:list` subcommands are gaining `--format json` while being ported from bash to Go. A command-injection fix in the docker-options eval path landed in v0.38.25.
◆ Where it's heading
The single-host Docker PaaS Dokku started as is increasingly a front-end for a Kubernetes backend. Across these ten releases nearly every new feature touches either scheduler-k3s or machine-readable output, and almost none touch the original Docker-only path. The bash-to-Go port running underneath reads as groundwork for the structured-output work rather than a refactor for its own sake.
◆ Prediction
Expect `--format json` to keep spreading across the remaining bash subcommands, and k3s to keep absorbing the certificate and networking controls the nginx and Traefik paths already have.
Robusta
5.0INFRA · APIS
Robusta's alpha train keeps widening what can push alerts in and where it can run.
◆ Current state
Robusta ships alpha releases every one to three weeks, each a small bundle of merged PRs rather than a headline feature. The recent four cover alert ingestion breadth (Jira Service Management, F5 Distributed Cloud documented against the Send Events API), operational plumbing (JSON log format behind an environment variable, a global imagePullSecret for the Helm chart, namespace-scoped RBAC guidance), and routine dependency and CVE bumps. The 0.47.0 release adds a workflow trigger action, letting one Robusta workflow fire another on the platform.
◆ Where it's heading
The pattern is integration breadth plus operability, not new product surface: more systems that can push events in, more ways to run the agent inside a locked-down cluster. Structured JSON logging and the namespace-scoped RBAC guide both read as groundwork for regulated and multi-tenant deployments where a cluster-wide agent is a non-starter. Workflow chaining is the one thread here that could grow past plumbing, since triggering workflows from workflows is where automation stops being one-shot alert handling.
◆ Prediction
The next alpha will most likely continue the same mix — another event source or two alongside dependency and CVE bumps. Whether workflow chaining becomes a real automation layer cannot be judged from these four releases.
