Jackett vs Robusta: at a glance
What is Jackett?
Jackett ships daily; every release is tracker-definition upkeep, never product change.
Jackett is in pure maintenance cadence: a tagged release lands most mornings, and each one is a batch of auto-generated commits against indexer YAML definitions. The last ten releases contain domain bumps, category-mapping corrections, selector fixes, and the occasional tracker added or removed. Nothing in this window touches the daemon, the Torznab API surface, or the UI.
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.

Jackett ships daily; every release is tracker-definition upkeep, never product change.
◆ Current state
Jackett is in pure maintenance cadence: a tagged release lands most mornings, and each one is a batch of auto-generated commits against indexer YAML definitions. The last ten releases contain domain bumps, category-mapping corrections, selector fixes, and the occasional tracker added or removed. Nothing in this window touches the daemon, the Torznab API surface, or the UI.
◆ Where it's heading
The project's value is the freshness of its indexer catalog, not its feature set, and the release stream reflects that exactly — churn tracks how often trackers move domains or change markup, not any roadmap. Recent entries show a slow drift toward API-based indexer integrations (simurg and desigaane both moved to API-key authentication) instead of HTML scraping, which is the only structural change visible here. Coverage keeps rotating as dead trackers are dropped and new ones land.
◆ Prediction
Expect the same daily definition-update rhythm to continue, with more indexers migrating from scraped selectors to native API or Torznab endpoints where sites expose them. The entries give no signal about changes to Jackett itself.
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.
