LoopX
huangruiteng
Provider-neutral state kernel and local-first control plane for governing long-running AI agent loops across Codex, Claude Code, Cursor, and peer teams.
Key features
- Loop-Engineering State Kernel: A compact durable-state layer that keeps objectives, gates, todos, evidence, quotas, and handoffs consistent across many bounded turns.
- Runtime-Agnostic: Governs work executed by any coding-agent runtime — Codex, Claude Code, Cursor, or your own — without replacing them.
- Peer-Agent Model: Registered agents are peers; claims, leases, capabilities, and typed continuation decide who acts next, with no durable leader identity.
- Kanban-Style Control Plane: Cards carry identity, authority, evidence, and continuation; moves are validated operators (claim, gate, monitor, writeback).
- Local-First: The control plane runs locally by default — the public/private boundary is explicit, so private data and code stay on your machine.
- Auto-Wake and Quotas: Quota-aware auto-wake keeps agents progressing on long-running goals without a runaway scheduler.
- Evidence & Continuation: 200+ hour example loops preserve decision lineage, evidence branches, and invalid experiments across turns.
- Human-In-Command: Dangerous permissions, publishing, and production writes remain gated to the human owner — not autonomous.
Best for
- Multi-Day SWE Loops: Drive week-long engineering objectives across many bounded agent turns while keeping scope and review state intact.
- PR/Issue Automation: Preserve review state, evidence, and reviewer preferences across a PR that touches multiple turns and agents.
- Auto-ML Experiments: Keep hypotheses, matched evidence, invalid lineages, and promote/stop gates visible in a single graph over hundreds of hours.
- Multi-Agent Coordination: Coordinate a peer team of Codex + Claude Code + Cursor agents on the same objective with typed handoffs.
- Recurring Monitors: Run heartbeat or monitoring loops with owner-visible gates and evidence trails.
- Creator/Research Workflows: Give non-engineering owners a legible board of long-running work with human sign-off at each gate.

Strix
Strix
Strix is an open-source AI pentesting agent that dynamically finds, exploits, and reports on real vulnerabilities in your applications.
Key features
- Autonomous AI Pentesters: Runs code dynamically like real hackers to discover vulnerabilities rather than relying on static pattern matching.
- Real Exploit Validation: Produces working proofs-of-concept for each finding so teams triage real issues instead of false positives from legacy scanners.
- Multi-Agent Orchestration: Teams of AI pentesters collaborate on reconnaissance, exploitation, and validation and scale across large surfaces.
- Developer-First CLI: Actionable findings surfaced through a command-line interface with concrete remediation guidance for engineers.
- CI/CD Integration: GitHub Actions and pipeline integration to automatically scan every pull request and block insecure code before it reaches production.
- Auto-Fix and Compliance Reports: Generates suggested patches and produces compliance-ready pentest reports for auditors and customers.
Best for
- Application Security Testing: Detect and validate critical vulnerabilities in web and API applications during development.
- Rapid Penetration Testing: Complete pentests in hours instead of weeks and produce compliance-ready reports for SOC 2, ISO, or PCI.
- Bug Bounty Automation: Automate reconnaissance and PoC generation to accelerate bug-bounty research and reporting.
- CI/CD Security Gates: Block insecure pull requests by running Strix on every commit in GitHub Actions before merge.
- Continuous Compliance Monitoring: Keep production environments audited by running scheduled Strix scans and archiving report artifacts.
