Arco: the ChatPlayground.ai alternative with 400+ models on your own key, on your Mac.
ChatPlayground.ai gives you around 30 models they picked, in a browser tab, for $180 a year. Arco lets you pick from 400+ models on your own OpenRouter key, pay only for the tokens you actually use, and keeps every chat on your Mac.
The short version
Skip the scroll and get the verdict.
Where Arco wins
- 400+ models via your own OpenRouter key
- Chats stay on your Mac, never uploaded
- Pay only when you use it. No monthly bill
Where ChatPlayground.ai falls short
- Only ~30 curated models, no BYOK

- $20 a month even when you barely use it
The verdict
Pick ChatPlayground.ai if you're on Windows or Linux, or if you want a browser tab you never have to configure. Pick Arco if you're on a Mac, want access to every model on OpenRouter, care where your chats live, and don't want another monthly subscription.

Three reasons people switch
The specific things ChatPlayground.ai can't match.
400+ models on your key, not 30 they picked for you.
ChatPlayground.ai gives you a curated shortlist of around 30 models. Whatever they integrated is what you get. Arco connects to OpenRouter, so you can pick from 400+ models today and add whatever ships tomorrow by pasting a model ID. No waiting for their roadmap.
Your chats stay on your Mac. Not in a browser tab that talks to their servers.
ChatPlayground.ai says they don't store your conversations, but every prompt still transits their infrastructure. You are trusting their claim. Arco stores everything locally. There is no Arco server your prompt has to pass through, because we don't run one.
One payment, then it's yours. No renewal notices.
ChatPlayground.ai charges $20 a month, or $180 a year on the annual plan. Skip a month and you still pay for that month. Arco is a one-time thing. Buy it once, keep it. Your only ongoing cost is the OpenRouter tokens you actually use.
What you actually pay over 3 years
ChatPlayground.ai bundles its subscription with API access. Arco separates them. You buy the app once and pay OpenRouter directly for the tokens you actually use. Here is the breakdown.

(yearly)
The fine print worth knowing
- The Lifetime Deal isn't shown on their homepage. ChatPlayground.ai offers a $575 lifetime tier (marked down from $875), but you only see it after creating an account and digging into the billing page. The public landing page shows the $20/month and $15/month options only. Arco's pricing is on the homepage.
- Every ChatPlayground.ai user needs their own subscription. No team-seat discount surfaced on their public pricing.
- ChatPlayground.ai requires Chrome and their browser extension. Firefox and Safari users can't use it as their default browser.
- Arco's ongoing cost is your OpenRouter usage. It can be $0 in a light month. ChatPlayground.ai bills the flat rate whether you used it or not.
