A side-by-side comparison of Backplanes Spotlight and Fabraix — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Backplanes Spotlight
Backplanes
Automatic session reports for Claude Code and Codex agents showing files touched, commands run, external tools reached, scope drift, and review items.
Key features
- Automatic Session Reports: Produces per-session reports for Claude Code and Codex that summarize actions, touched files, commands executed, and external calls to third-party tools.
- File-Level Traceability: Identifies and lists files created, modified, or deleted during an agent session so reviewers can inspect exact changes and their context.
- Command and Action Logs: Captures commands and high-level actions executed by agents (shell commands, IDE operations, tool invocations) to recreate and audit workflows.
- External Tool Interaction Tracking: Records which external services or tools the agent reached (APIs, CLIs, cloud services) to surface potential data exfiltration or dependency use.
- Scope Drift Detection: Highlights when an agent’s actions diverge from the original task or intent, flagging areas that need human attention or rollback.
- Review Prioritization: Flags risky or unusual operations and ranks items deserving human review to reduce time spent on low-value checks.
- Session Timeline Visualization: Provides chronological timelines of agent activity to help investigators and engineers follow execution flow and reconstruct decisions.
- Organizational Oversight: Aggregates agent activity across teams and vendors to enable multi-tenant monitoring, accountability, and governance.
- Automatic session report generation for agent runs
- Explicit support for Claude Code and Codex sessions
- Tracks files touched/modified during a session
- Records commands executed by the agent
- Tracks external tools and APIs reached during execution
- Detects scope drift across the session
- Highlights actions and artifacts that deserve manual review
- Free at launch
Best for
- Security & Incident Review: Investigating a suspicious agent session to see which files were accessed, which external APIs were called, and whether sensitive data may have been exposed.
- Vendor and Contractor Oversight: Monitoring agent-driven work performed by third-party vendors to ensure actions stay within scope and comply with internal policies.
- Code-Generation QA: Reviewing outputs from Claude Code or Codex sessions to validate generated code changes, commands executed, and identify potential regressions.
- Compliance and Audit Trails: Providing auditable records of automated agent activity for regulatory or internal compliance purposes, including timeline and action logs.
- Scope Management: Detecting and correcting scope drift when an agent starts performing tasks outside the intended objective, preventing unintended changes.
- Postmortem & Debugging: Reconstructing agent workflows after a failure to determine root cause by reviewing chronological actions, file edits, and external calls.
- Change Control and Approval: Using prioritized review items to gate merges or deployments that were initiated or modified by agent sessions.
- Developer audit of autonomous code-generation or modification runs
- Security and compliance review of agent interactions with external tools and systems
- QA and debugging to reproduce and understand agent-driven changes
- Review prioritization by surfacing risky or out-of-scope actions
- Post-run reporting for teams integrating agent workflows into CI/CD
Fabraix
Fabraix
An adversarial staging environment and open playground to find gaps in AI agents through live red-teaming and verification.
Key features
- Live Adversarial Playground: Deploys fully functional AI agents in live challenge environments so researchers and attackers can probe real capabilities rather than toy or mocked scenarios.
- Published System Prompts: System prompts and agent configurations are published openly to ensure transparency and reproducibility of challenges and defenses.
- Versioned Challenge Configs: Challenge definitions and configuration files are stored and versioned in public repositories, enabling traceability and collaborative iteration on tests and fixes.
- Autonomous Red‑Teaming Agents: Provides or links to autonomous agents and tooling that systematically probe target systems to discover failure modes and bypasses.
- Exploit Documentation and Remediation Sharing: When a technique succeeds, the winning method is documented and shared so defenders can learn common weaknesses and implement fixes.
- Community Contribution Model: Encourages external contributors to submit new challenges, attacks, and mitigations to expand coverage and collective understanding.
- Open-Source Repositories and Licensing: Maintains public GitHub repositories (Playground and related tools) with code, challenges, and license files to support adoption and auditing.
- Runtime Security Focus: Orients testing and tooling toward protecting live agent behavior and interactions, not just static model evaluation.
