• Corelayer - Agentic production support platform that proactively investigates, resolves, and prevents incidents, with BYOC and on-prem support for regulated environments.

• YYLO - Command-line orchestrator for coding agents, repeatable workflows, and receipt-backed repository changes. Each task freezes the protected target SHA and creates a dedicated branch/worktree behind typed task, validation, merge, and release-readiness boundaries; the merge queue owns risk-based review, and workflow runs retain declared receipt hashes and terminal manifests. MIT, on npm as @yylo/cli; orchestrates Pi and Codex subagents.

• KubeIntellect - Open source (AGPL-3.0) multi-agent Kubernetes SRE agent. Investigates a live cluster via kubectl, Prometheus (PromQL) and Loki (LogQL) and explains root cause in plain English. Every mutating operation stops for human approval enforced at the tool boundary, with role-based access control and a hash-chained decision log.

• heliograph (open source) - CLI and agent skill for debugging hosts you have no access to, for air-gapped, client-owned and change-controlled estates. Diagnostic steps go out over a private git repo, an on-site operator or an unattended runner executes them, and the logs come back the same way with every line timestamped in UTC.

• Nexus Shell Agent Bridge - Local macOS MCP bridge that lets approved AI agents operate visible SSH terminals, transfer files, and inspect read-only server and network monitoring without receiving stored passwords or private keys.

• ai-economics-mcp - MCP server that prices agent operations before they run: token cost across vendors, fully-loaded agent-hour cost including human review, model-routing savings, and the reviewer capacity a given agent fleet actually needs. 12 calculators by Michał Piszczek (piszczek.pl/tools), MIT, free keyless API.

• Aiden for SRE - Aiden that acts autonomously on recurring incidents and works complex ones alongside your team through to resolution — policy-bound and fully auditable.

• OpenSRE (opensre.in) - Self-hosted AI SRE platform for incident investigation with episodic memory, a Neo4j knowledge graph, Web UI, Slack, and Teams.

• Aient AI - OpenTelemetry-native AI SRE agent that ingests logs, metrics, and traces, groups errors into problems, investigates root cause, and opens a GitHub pull request with a fix, then monitors production telemetry for recurrence. Integrates with GitHub, Slack, and Linear, and exposes a hosted MCP server. (docs)

• Chronicle - AI-native incident response and operational memory platform featuring alert deduplication, multi-source ingestion, host telemetry, semantic runbook and historical incident retrieval, SLA automation, and AI-assisted root cause analysis.
