AgentLoop vs Backplanes Spotlight: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of AgentLoop and Backplanes Spotlight — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
AgentLoop
Edward Yi
AgentLoop turns a single ChatGPT plan into unattended Codex worker + independent-critic cycles that build against your local rubric until the work passes.
Key features
- Fresh Worker Per Cycle: Each build cycle spawns a clean Codex worker with fresh context so long-running loops do not accumulate stale state or memory drift.
- Independent Critic Process: A separate fresh process grades every result against your rubric so passing tests never become permission to stop looking.
- Rubric in GUIDELINES.md: Definition-of-done lives as plain Markdown in your repo and is read on every cycle, so standards persist while prompts do not.
- Evidence Carried in Files: Worker output, critic verdicts, and fixes are written to project files so the next cycle inherits the actual state of the work.
- Bounded Goal + Cycle Budget: You cap the loop with a goal.md and cycle budget so unattended runs stop at a predictable ceiling.
- MCP Status Interface: Ask ChatGPT for status through MCP so you can monitor cycles, verdicts, transcripts, and cost without opening the dashboard.
- Local-first Install: git clone the pinned v1.1.0 release and run node src/daemon.js — no npm install, no hosted workspace, MIT licensed.
Best for
- Shipping a bounded feature: Add a CSV export across UI, API, and regression suite while the critic enforces end-to-end behavior and edge cases.
- Migration work: Run an unattended migration where fresh workers apply the change and the critic verifies each step against a rubric.
- Hardening pass: Give AgentLoop a hardening goal so it iterates on defects the existing test suite misses, like malformed input handling.
- Product polish loop: Point AgentLoop at a polish goal with clear acceptance criteria and let it converge to VERDICT: PASS.
- Unattended overnight runs: Kick off a long loop, monitor cycle verdicts, and cancel from the dashboard or via MCP when the receipt looks right.
- Enforcing team standards: Codify team engineering standards in GUIDELINES.md so every worker builds against the same definition of done.
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
