Can Prometheus by Firecrawl be run from a terminal or IDE?

The fact sheet only documents a web-based platform with no local installation, so CLI and IDE integration are not on file.

What is the cheapest published Codex plan?

Free at $0/month, with Go at $8/month and Plus at $20/month above it, then Pro 5x at $100/month and Pro 20x at $200/month.

Is Prometheus by Firecrawl pricing public?

No. The directory lists pricing model, starting price, and verified plans all as not recorded or none on file, so cost must be checked directly with Firecrawl.

What customization primitives does Codex ship with?

The fact sheet flags Codex as having fewer built-in customization primitives than some rivals, specifically mentioning fewer hooks and sub-agents than competing tools.

Codex vs Prometheus by Firecrawl: How They Actually Differ

Codex suits solo founders who write code across CLI, IDE, and cloud and want GPT-5 GitHub pull request reviews on a published plan ladder from $0/month up through Pro 20x. Prometheus by Firecrawl suits small teams that need a browser-based forward deployed agent to turn websites into LLM-ready data, though its pricing is not on file.

Compiled 2026-10-19 from our catalogue entries for Codex and Prometheus by Firecrawl.

The short answer

Pick Codex if: You want a coding agent that runs across CLI, IDE, desktop and cloud, reviews GitHub pull requests on GPT-5 models, and ships with a published plan ladder running from Free at $0/month up through Pro 20x at $200/month, with an API option.
Pick Prometheus by Firecrawl if: You want a web-based forward deployed agent that automates web data collection and processing into LLM-ready form from a Y Combinator-backed vendor, and you do not need a desktop app, CLI, or IDE integration.
Cheapest way in: Codex Free at $0/month is the only published starting price in the directory. Prometheus by Firecrawl has pricing model, starting price, and verified plans all listed as not on file, so direct cost comparison is not possible.
What we could not compare: Prometheus pricing tiers, plan names, full platform list beyond the web-based interface, and any feature or cost parity against Codex plans are not on file.

Both listings sit in the AI Coding Agents category, but they solve different jobs. Codex is OpenAI's coding agent that runs the same agent across a terminal CLI, an IDE extension, a desktop app, and a cloud environment, with cloud code reviews that comment inline on GitHub pull requests. Prometheus by Firecrawl is a forward deployed agent focused on collecting and processing web data into LLM-ready form, built by a Y Combinator-backed company whose core specialty is converting websites into structured data.

The directory files the two products very unevenly. Codex has verified plans ranging from Free at $0/month up through Pro 20x at $200/month, an API option that charges per token, and a full platform list covering web, Mac, Windows, Linux, CLI, and a VS Code extension. Prometheus by Firecrawl has no pricing on file, no platform list beyond a web-based interface, and no documented plan tiers, so any team evaluating it must contact Firecrawl directly to scope cost and availability.

Where Codex is the better fit

One agent spans CLI, IDE, desktop and cloud, so work started on one surface can continue on another.
Cloud code review on a GitHub pull request that comments inline and proposes fixes, running on OpenAI's GPT models with GPT-5.5 listed as the current recommended frontier model.
Reads the shared AGENTS.md standard and supports MCP tools, and is included with ChatGPT plans from the Free tier up through Pro.

Which one should you pick?

Solo founder writing and reviewing code across terminal, IDE, and GitHub

Codex

Cross-surface agent, GPT-5-powered cloud PR reviews, AGENTS.md and MCP support, and a published Free through Pro 20x plan ladder are all documented on file.

Small team pulling structured web data into an LLM or agent workflow

Prometheus by Firecrawl

It is a forward deployed agent for web data collection from a Y Combinator-backed web-to-structured-data vendor and runs on a web-based platform with no install step, though pricing is not on file.

Verified plans (read 2026-08-21): Free $0 /month | Go $8 /month | Plus $20 /month | Pro 5x $100 /month | Pro 20x $200 /month | Business / Enterprise Not published | API Key Pay only for the tokens Codex uses, based on API pricing
Strengths on file: Runs one agent across CLI, IDE, desktop, and cloud — work moves between surfaces.; Strong GitHub integration: a cloud code review on a 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.
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.

## Prometheus by Firecrawl (/tools/prometheus-by-firecrawl)
Tagline: A Forward Deployed Agent for web data.
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: Developed by Firecrawl, a Y Combinator-backed company specializing in converting websites into LLM-ready data.; Positioned as a forward deployed agent aimed at automating web data collection and processing tasks.; Accessible through a web-based platform without requiring local installation.
Prometheus by Firecrawl is a forward deployed agent for collecting and processing web data. It automates web data collection and processing tasks rather than leaving them as manual scraping work.
It comes from Firecrawl, a Y Combinator-backed company that specializes in turning websites into LLM-ready data, so the web-to-structured-data focus is the core of the product. You run it through a web-based platform with no local installation.
It fits teams that want to pull structured web data into agent or LLM workflows and are fine working entirely in the browser. It's a weaker fit if you need a desktop app, CLI, or IDE integration, since it's currently listed only as a web platform with none of those documented. Pricing is not publicly disclosed, so you'll need to check directly before budgeting.
Among AI coding agents in the directory, it sits on the data-ingestion side rather than the code-writing side, aimed at feeding web data to agents instead of generating application code.
