Reddit publishing as software
Codex runs postqueen commands, reads the JSON results and verifies each step, so your Reddit pipeline behaves like any other task it automates in CI or cron.
RedditAutomate Reddit with Codex
Point Codex at the postqueen CLI and it creates, schedules and verifies Reddit posts as one repeatable task you can rerun any time.
Quick start
Set up the CLI inside the workspace Codex uses, then describe the Reddit outcome you want in the task prompt.
Codex session
# Inside a Codex sessionnpm install -g postqueenexport POSTQUEEN_API_KEY=your_api_key # Then prompt:# "Create this week's Reddit posts# from notes.md and schedule them# with postqueen"What Codex can run on Reddit
Windows that fit Reddit
Tell Codex when your subreddits are busiest and it schedules posts into that window on Reddit, day after day, without reminders.
Community rules respected
Codex targets the exact subreddits you choose and keeps every submission reviewable, so you can check each one against community rules first.
Drafts until you are ready
Ask Codex for drafts only. They sit on the postqueen calendar unscheduled, so you can edit them and pick the time yourself, and nothing reaches your community members on Reddit until you do.
Three steps to a full queue
Discover Reddit
Codex calls postqueen to list your connected subreddits and sees what Reddit supports, so drafts start from real capabilities, not guesses.
Draft with Codex
Give it the brief. The agent writes Reddit-shaped posts and proposes publish times that match when your community members are around.
Check and publish
Look over the queue on the postqueen calendar and change anything you want. postqueen publishes each post at its time, and Codex can pull the results after.
What Reddit allows
Codex reads these limits from postqueen before it composes, so a draft that would be rejected never reaches the queue.

F.A.Q.
Frequently asked questions
How does Codex connect Reddit to postqueen?
Install the postqueen CLI where Codex runs commands and export your API key. Every command returns JSON, so the agent can create, schedule and list Reddit posts reliably.
Can Codex schedule Reddit posts at exact times?
Yes. Give it exact slots or a rule like mornings at nine and it sets publish times on the posts it creates, keeping your subreddits active on a steady rhythm.
Will Codex publish to Reddit on its own?
Only if you ask it to. Tell it to save drafts and nothing is scheduled: the posts wait on the calendar until you set a time. Tell it to schedule, and they go out at the times you can see, which is the setup most people move to once they trust the output.
Can one brief cover Reddit and other channels too?
Yes. postqueen connects 30 channels, so Codex can turn the same brief into Reddit posts plus adapted versions for every other channel you run.
Does Codex access cost extra on postqueen?
No. The agent uses your regular API key and plan limits: unlimited posts on every plan, and channel counts from 5 on Creator up to uncapped on Ultimate.
Can the AI assistant write Reddit posts?
Yes, and it aims for the plain, human tone Reddit rewards rather than marketing speak. Treat drafts as a starting point, edit them honestly, and schedule them once they read right. Redditors are quick to spot copy that was not written for them.
What does postqueen track for Reddit?
A full history of what was posted to which subreddit and when, shared with your team through drafts and comments. Votes and comments live on Reddit itself, and your post history in postqueen makes it easy to find and check each submission.
