Codex vs Spotlight by Backplanes: How They Actually Differ
Codex is the coding agent itself — it writes code across CLI, IDE, desktop, and cloud on GPT models. Spotlight is a reporting layer that reads Codex or Claude Code sessions and produces review reports in a browser. They solve different problems and can be used together.
Compiled 2026-09-03 from our catalogue entries for Codex and Spotlight by Backplanes.
The short answer
- Pick Codex if
- You need an active coding agent that writes and reviews code across the terminal, IDE, desktop, and cloud, and you want GitHub pull-request reviews and MCP support out of the box.
- Pick Spotlight by Backplanes if
- You already run Claude Code or Codex and want a web-based reporting layer that turns those sessions into review reports to improve how you work.
- Cheapest way in
- Codex has a documented free tier at $0/month, with paid plans starting at $8/month (Go). Spotlight pricing is not recorded in our fact sheet.
- What we could not compare
- Spotlight by Backplanes has no recorded pricing, no recorded platforms list beyond a web interface, and no documented plan tiers. Its integration depth beyond 'session reports' is not on file.
These two products sit at different points in a coding workflow. Codex is OpenAI's agentic coding tool: one agent that works in the terminal CLI, an IDE extension, a desktop app, and a cloud environment, running on OpenAI's GPT models (GPT-5.5 listed as the recommended frontier model). It reads the shared AGENTS.md standard, supports MCP tools, and can spin up a cloud code review on a GitHub pull request that comments inline and proposes fixes. It is included with ChatGPT plans from the free tier up through Pro.
Spotlight by Backplanes is a smaller, narrower tool. It generates session reports for Claude Code and OpenAI Codex, working through a web-based interface. It does not write code itself; it reads coding-agent sessions and turns them into reports. Its web-only setup is also its main limit — there is no native IDE or terminal extension listed, so the reports live in the browser rather than in your editor.

Where Codex is the better fit
- One agent runs across CLI, IDE, desktop, and cloud, so work started in one surface continues in another.
- Cloud code review on a GitHub pull request that catches real bugs and proposes fixes.
- Reads the shared AGENTS.md standard and supports MCP tools.
- Included with ChatGPT plans from the free tier up through Pro, with a documented $0/month entry point and tiered paid plans up to Pro 20x at $200/month.
Where Spotlight by Backplanes is the better fit
- Generates session reports for OpenAI Codex usage.
- Generates session reports for Claude Code usage.
- Accessible through a web-based interface, so there is no local install to manage.
Which one should you pick?
It writes code across CLI, IDE, desktop, and cloud on GPT-5 models, and the free tier at $0/month removes the price question while you try it.
Its stated purpose is to turn Codex sessions into reports, which gives you an analysis layer on top of the agent itself.
It is one of the two agents Spotlight lists as supported, alongside Codex.
The fact sheet lists a cloud code review on a pull request that comments inline and proposes fixes; Spotlight does not list that capability.
Frequently asked questions
- Do Codex and Spotlight compete with each other?
- Not directly on the fact sheet. Codex is the coding agent that writes code; Spotlight is a reporting layer that reads Codex or Claude Code sessions. The fact sheet describes them as solving different jobs in the same workflow.
- Can I use both at the same time?
- Yes, on paper. Spotlight lists Codex as one of the two agents it generates reports for, so running Codex for code work and Spotlight for session analysis is consistent with what the sheet describes.
- What does Spotlight cost?
- Pricing is not recorded on the fact sheet. There are no verified plans on file. Codex, by contrast, has a documented free tier at $0/month and paid tiers up to $200/month.
- Which AI models do they run on?
- The fact sheet says Codex runs on OpenAI's GPT models, with GPT-5.5 listed as the recommended frontier model, and is locked to those GPT models with no Claude or Gemini out of the box. Spotlight does not generate code itself; it reports on sessions from Claude Code and Codex.
- Does Spotlight work in my editor?
- The fact sheet lists only a web-based interface for Spotlight and notes there is no native IDE or terminal extension. Codex, by contrast, is listed across web, mac, win, linux, cli, and a VS Code extension.

Limits on file: Locked to OpenAI's GPT models — no Claude or Gemini out of the box.; Fewer built-in customization primitives (hooks, sub-agents) than some rivals. Codex is OpenAI's agentic coding tool. It runs the same agent across a terminal CLI, an IDE extension, a desktop app, and a cloud environment, so work started in one surface can continue in another. It reads the shared AGENTS.md instructions file, speaks the Model Context Protocol (MCP), and can spin up a cloud code review on a GitHub pull request that comments inline and proposes fixes. Codex runs on OpenAI's GPT models — currently GPT-5.5 as the recommended frontier model — and is included with ChatGPT plans, from the free tier up through Pro. ## Spotlight by Backplanes (/tools/spotlight-by-backplanes) Tagline: Session reports for Claude Code & Codex to improve your code Category: AI Coding Agents Pricing model: not recorded Starts at: Not recorded Platforms: not recorded Public repo: none listed Docs: none listed Verified plans: none on file Strengths on file: Generates session reports for Claude Code usage.; Generates session reports for OpenAI Codex usage.; Accessible through a web-based interface. Limits on file: Only supports Claude Code and Codex, not other AI coding agents. Spotlight by Backplanes is a tool that generates session reports for Claude Code and OpenAI Codex to help you improve your code. Its focus is narrow on purpose: it reads your coding-agent sessions and turns them into reports, working through a web-based interface. That web-only setup is also its main limit — there's no native IDE or terminal extension, so the reports live in the browser rather than in your editor. It fits developers who run Claude Code or Codex and want a review layer over how those sessions went. It won't fit teams on other AI coding agents, since it supports only those two. Among coding-assistant tools, Spotlight sits on the analysis side rather than the code-generation side, reporting on agent sessions instead of writing the code itself.
