What is Reflex?

Reflex is a self-hosted Kubernetes remediation tool that automatically fixes SLO breaches using Prometheus data. It watches your service level objectives, detects when they trip, and executes actions like restart, scale, or rollback—either with your approval or fully autonomously. Users deploy it via Helm in about five minutes, and it runs entirely inside their own cluster, ensuring no data leaves their infrastructure.

Application scenarios

  • Nighttime incident response

    When a cluster breaches at 3am, Reflex automatically fixes it without waking up an on-call engineer.

  • SLO-based auto-remediation

    Teams can set up Reflex to watch Prometheus SLOs and take action when error rates exceed thresholds (e.g., 82% error rate vs. 5% threshold).

  • Gradual trust building

    Start in observe mode to see what Reflex would do, then promote to dry-run (Slack approval required), and finally to auto mode when confident.

  • Air-gapped environments

    The free tier has no external dependencies, making it suitable for isolated clusters.

  • Side-by-side evaluation

    Run Reflex alongside Robusta or PagerDuty automation to compare which works best for your team.

  • AI-assisted root-cause analysis

    On Pro tier, Reflex uses AI (BYOK OpenAI/Anthropic) to analyze breaches when no curated pattern matches.

Core Features

  • SLO breach detection

    Reflex watches your SLOs in Prometheus and instantly detects when thresholds are exceeded.

  • Curated remediation patterns

    Ships with pre-built patterns for common breach types—restart, scale, or rollback—so you don't need to write custom playbooks.

  • Trust ladder (observe → dry-run → auto)

    Start in observe mode (logs would-be actions), graduate to dry-run (Slack approval required for each action), then promote to auto mode where Reflex acts and tells you after.

  • Slack approval buttons

    When a breach is detected, Reflex posts the exact remediation to Slack with Approve/Reject buttons for manual confirmation.

  • Cooldown and precondition safeguards

    Each Reflex has a default 10-minute cooldown to prevent loops, plus preconditions that block actions when the system is unhealthy (e.g., already at max replicas, recently-failed action).

  • Global rate limiting

    Auto mode honors a global rate limit to prevent cascading failures.

  • AI root-cause analysis (Pro tier)

    When no curated pattern matches, Reflex runs an AI reasoner (BYOK OpenAI/Anthropic) with JSON validation and a 500-token ceiling, showing results to a human before any action.

  • Self-hosted controller

    Reflex Runtime is a single self-hosted controller that runs in your cluster with no data leaving.

  • Unlimited clusters

    Both free and Pro tiers support unlimited clusters.

  • AI disable option

    You can disable AI entirely using `--set ai.enabled=false`.

Target users

Site reliability engineers (SREs), DevOps teams, and platform engineers who manage Kubernetes clusters and want to automate incident response without writing custom playbooks. Also suitable for teams that need to gradually build trust in automation before going fully autonomous.

How to use Reflex?

  1. Install Reflex via Helm in about five minutes (helm install).
  2. Configure your SLOs in Prometheus and set up Reflex to watch them.
  3. Start in observe mode to see what actions Reflex would take (no cluster changes).
  4. Promote to dry-run mode when recommendations look correct—Reflex posts remediation to Slack for your approval.
  5. Graduate to auto mode when you trust the tool—Reflex acts automatically and notifies you after.
  6. For Pro tier, optionally enable AI root-cause analysis by bringing your own OpenAI or Anthropic key.

Pricing and free trial

  • Free ($0/month): 3 SLOs, 3 Reflexes, observe mode (logs would-be actions), Slack notifications, unlimited clusters.
  • Pro ($149/month): Unlimited SLOs, unlimited Reflexes, observe + dry-run + auto modes, Slack approval buttons, AI root-cause analysis (BYOK OpenAI). Cancel anytime. Self-hosted.

Effect review

Reflex delivers exactly what it promises: a simple, safe way to automate Kubernetes remediation without requiring custom playbooks. The trust ladder is the standout feature—it lets teams start with zero risk in observe mode and gradually promote to full automation on their own timeline. The safeguards (cooldowns, preconditions, global rate limits) show real-world thinking about cascading failures. For $149/month, the Pro tier is reasonably priced for unlimited SLOs and AI-powered analysis, especially since it's self-hosted and your data never leaves the cluster. The main limitation is that you need Prometheus already in place, and the AI reasoner is only available on Pro with your own API key.

Frequently Asked Questions

What is Reflex?
Reflex is an AI tool that automates Kubernetes remediation using SLOs and intelligent trust ladders to catch and resolve issues early without manual intervention.
How does Reflex detect issues?
Reflex monitors SLOs (Service Level Objectives) and uses intelligent trust ladders to identify potential problems before they escalate.
Does Reflex require manual setup?
Reflex automates remediation, but initial configuration of SLOs and trust ladders may require some setup to align with your environment.
Can Reflex integrate with existing Kubernetes clusters?
Yes, Reflex is designed to integrate with Kubernetes clusters and works alongside existing monitoring and alerting systems.
What are trust ladders in Reflex?
Trust ladders are intelligent escalation paths that determine the level of automation and human oversight needed for remediation actions.
Is Reflex suitable for production environments?
Yes, Reflex is built for production use, providing automated remediation to minimize downtime and reduce manual toil.
