Codex vs Oxlo.ai: How They Actually Differ
Codex suits solo founders who want one agent across the terminal, IDE, desktop, and cloud, plus GitHub pull-request review. Oxlo.ai suits cost-focused teams that prefer routing work across multiple models and can work in a browser. Codex has a published free tier; Oxlo.ai pricing is not recorded.
Compiled 2026-10-24 from our catalogue entries for Codex and Oxlo.ai.
The short answer
- Pick Codex if
- You want work to continue across a terminal CLI, IDE extension, desktop app, and cloud, and you want cloud code review on GitHub pull requests. Codex is included with ChatGPT plans, from the free tier up through Pro.
- Pick Oxlo.ai if
- Reducing cost per task is your priority and a browser-based workflow is acceptable. Oxlo.ai routes AI coding workloads across multiple models to reduce spend rather than pinning you to one provider.
- Cheapest way in
- Start with Codex's Free plan at $0/month. Oxlo.ai's starting price, pricing model, and plans are not recorded, so we cannot say whether its entry cost is lower.
- What we could not compare
- Oxlo.ai's price, verified plans, and platform list are not recorded, so we cannot compare running costs or supported surfaces side by side. For both products, no docs or public repo are listed.
Both are listed in the AI Coding Agents category, but they take different approaches. Codex runs OpenAI's GPT-5 models and runs the same agent across a terminal CLI, IDE extension, desktop app, and cloud, so work started in one surface can continue in another. It can also spin up a cloud code review on a GitHub pull request that comments inline and proposes fixes.
Oxlo.ai runs entirely in a browser and routes AI coding work across multiple models to cut the cost per task. Its stated edge is cross-model cost control rather than one provider's output. The fact sheet says it has no documented native IDE extensions and does not publish a pricing tier.

Where Codex is the better fit
- One agent runs across CLI, IDE extension, desktop app, and cloud, so work can move between those surfaces.
- Cloud code review on a GitHub pull request that catches bugs, comments inline, and proposes fixes.
- Reads the shared AGENTS.md instructions file and supports MCP tools.
Where Oxlo.ai is the better fit
- Routes AI coding workloads across multiple models to reduce cost per task.
- Runs entirely in a browser.
- Does not pin you to one model provider; its stated focus is spreading work across several models to reduce spend.
Which one should you pick?
Codex is included with ChatGPT plans from the free tier up through Pro, and its Free plan is $0/month.
The same agent runs across those surfaces, and work started on one surface can continue on another.
Oxlo.ai routes workloads across multiple models to reduce cost per task, with browser-based access.
Codex lists cli and vscode-ext among its platforms. Oxlo.ai runs entirely in the browser and has no documented native IDE extensions.
Frequently asked questions
- What does Codex cost?
- Verified plans on file are Free $0/month, Go $8/month, Plus $20/month, Pro 5x $100/month, and Pro 20x $200/month. Business and Enterprise are not published. An API Key option means you pay only for the tokens Codex uses, based on API pricing.
- Can Codex use Claude or Gemini?
- Not out of the box. Codex is locked to OpenAI's GPT models. Oxlo.ai, by contrast, routes work across multiple models.
- Can I use Oxlo.ai inside my editor?
- The fact sheet says Oxlo.ai has no documented native IDE extensions and runs entirely in the browser. Its platform list is also recorded as not recorded, so we do not have its full surface list on file.
- Which one reviews GitHub pull requests?
- Codex, per the fact sheet. It can start a cloud code review on a pull request that catches real bugs, comments inline, and proposes fixes. No equivalent GitHub pull-request review capability is recorded for Oxlo.ai.
- Do either of these have public documentation or a repo?
- No docs or public repo are listed for either product in the fact sheet.

## Codex (/tools/codex) Tagline: OpenAI's coding agent — works in the terminal, IDE, and cloud, reviews GitHub pull requests, and runs on GPT-5 models. Category: AI Coding Agents Pricing model: freemium Starts at: Free — $0 /month Platforms: web, mac, win, linux, cli, vscode-ext Public repo: none listed Docs: none listed 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. ## Oxlo.ai (/tools/oxlo-ai) Tagline: Scale across AI models without scaling your bill 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: Operates as a web-based platform accessible through a browser.; Routes AI coding workloads across multiple models to reduce cost per task. Oxlo AI is a web-based coding-agent platform that routes AI coding work across multiple models to cut the cost per task. Its edge is model routing: instead of pinning you to one provider, it spreads workloads across several models to reduce spend, which is the point behind its "scale across AI models without scaling your bill" pitch. It runs entirely in the browser, so there are no documented native IDE extensions — a limit if your workflow lives in an editor. The pricing tier isn't publicly listed either, which makes it hard to compare costs before signing up. Among AI coding agents, Oxlo AI competes less on a single model's output and more on cross-model cost control, unlike tools tied to one provider or a specific IDE plugin.
