Install ProPR, or skip the server
Run npm install -g propr-cli and propr setup on a Linux Docker host (quickstart). ProPR Hosted runs a dedicated instance for you when you would rather not run one.
ProPR: the Augment Code alternative with no token markup
Augment Code's Cosmos, sold to Harness in October 2026, runs hosted agent fleets from ticket to reviewed pull request. ProPR runs that lifecycle on your own server: plan, isolated workspace, pull request, follow-up.
vs
Augment Code
Where they overlap
Both open pull requests and turn review feedback into fixes. ProPR does it with the agents you already subscribe to, self-hosted, with no token markup.
Cosmos pathTicket → hosted VM → draft pull request → PR FixerAugment hosts the agents, the sandboxes, and the model access.
ProPR pathPlan → isolated workspace → GitHub PR → follow-up commitYour agents, your server, no markup on tokens.
Switch from Cosmos to ProPR.
What you keep: your GitHub repositories and review process, and the Claude or ChatGPT plan ProPR runs through Claude Code or Codex.
The same ideas, ProPR's names
| Cosmos | ProPR |
|---|---|
| Cosmos session | Task |
| Ticket Manager spec | Plan, approved before code runs |
| PR Author expert | The implementing agent, chosen per task |
| Reviewer experts | /review by a second model |
PR Fixer on cosmos fix | /fix, or any plain PR comment |
| Provider price plus 40% service fee | Provider price, no markup |
From zero to the first pull request
Add the same repository and sign in your agent
Open the web UI, sign in with GitHub, and add the repository. Sign in Claude Code, Codex, or Antigravity CLI with the plan you already hold.
Start the first task and approve the plan
Add the AI label to the ticket's GitHub issue, then approve the plan.
Review the pull request in GitHub
Review the diff the way you review any pull request. A plain comment on it becomes the next commit on the same branch; /review posts scored findings and /fix applies them. The cross-model review playbook puts a different model on the review.
What stays with Cosmos: Augment hosts the agents, sandboxes, and model access; ProPR runs on a Linux Docker host you own or on a ProPR Hosted plan.
Augment covers a lot of the loop, and in October 2026 it sold Cosmos, the Auggie CLI, and the code context engine behind them to Harness. Cosmos runs each session in a fresh hosted VM, its PR Author expert turns a ticket into a draft pull request, its reviewer experts comment on the PR, and its PR Fixer responds to review findings and failing CI when you comment cosmos fix or configure automatic fixing. A Ticket Manager drafts a spec and waits for approval when a task needs one. You pick the model per session from Claude, GPT, Gemini, and others that Augment hosts. Flat plans run $20 and $100 per month, and model usage bills at the provider's list price plus a 40% service fee.
ProPR runs the same lifecycle on your own server: plan, isolated implementation, pull request, review, follow-up fixes. Claude Code, Codex, Antigravity CLI, Mistral Vibe, or OpenCode does the work on the subscription or API key you already pay for, and ProPR never marks up tokens.
Augment Code fits best when...
- You want a hosted platform that runs the agents, the sandboxes, and the model access for you.
- Named experts for authoring, reviewing, and fixing pull requests match how your team splits work.
- A flat platform fee plus a service fee on model usage is acceptable.
ProPR fits best when...
- You plan AI-generated changes before implementation and review them in GitHub PRs.
- Plain PR comments become follow-up commits from any of five agents on the same branch.
- Agents, repositories, logs, and credentials run on your own infrastructure, free under Apache 2.0.
Hosted agent fleets versus a self-hosted PR path.
