How Do You Switch From Browserbase to Solari?
Solari ships @solarisdk/browserbase-compat for Node and solari-browserbase-compat for Python, so Browserbase code runs on Solari after an import change.
The compat package keeps the sessions.create, retrieve, list and update calls of the Browserbase client, as the migration guide sets out.
Playwright, Puppeteer, Stagehand and browser-use connect to the session's connectUrl, a raw Chrome DevTools Protocol websocket, per the migration guide.
Do Saved Logins Carry Over?
A Solari profile saves a login, its cookies and its site data, so an agent signs in once and every later session starts signed in, as the profiles guide describes.
Existing Browserbase contexts become Solari profiles that keep cookies and localStorage, per the migration guide.
Solari's Professional plan includes 500 profiles.
What Else Runs on a Solari Account?
Browsers, sandboxes, VMs, proxies and captcha solves all draw from one Solari credit balance.
A Solari session turns on recording, stealth, proxies or a saved profile through opt-in session options.
Where Each Fits
Solari fits agent teams that want browsers, sandboxes and desktops behind one API.
Browserbase created and maintains Stagehand, the AI SDK for browser agents, as its pricing page says.
Browserbase is the more established vendor with the larger ecosystem; Solari is the younger company and moves faster on speed and price.
