How Does a Browser Agent Enrich a Lead?
A Solari browser agent enriches a lead in a real Chrome in the cloud, opening company sites, directories and signed-in data tools the way a person would.
Lead enrichment adds fresh contact details, firmographics and buying signals to the lead records already in a CRM.
Browserbase says CRM records "go stale within months" as titles change, companies move and contacts leave.
Why Does Lead Enrichment Need a Cloud Browser?
Solari Cloud Browsers are driven with Playwright or any CDP client, so the enrichment script you already run connects to them.
Browserbase says do-it-yourself scrapers "break the moment a source adds anti-bot protection".
Browserbase also says logged-in sources "lose their session every run, forcing repeated re-auth".

Solari creates a browser session in 8 ms, the median across 5,000 runs on Steel's open-source benchmark.
A complete Solari run, from create to release, averages 199.9 ms on the same benchmark.
The Solari results sit in pull request #4 on the browserbench repository, which is still open for anyone to rerun.
How Many Leads Can Solari Enrich at Once?
Solari runs 150 concurrent browsers on the Professional plan.
Solari supports up to 100,000 concurrent browsers on Enterprise, so you can enrich a whole territory list in one pass.
Solari stealth sessions carry their own concurrency cap of 50 on Professional and 75 on Team and Enterprise.
How Does Solari Keep an Agent Signed in to Data Tools?
A Solari profile saves your login, your cookies and site data, so your agent signs in to a data tool once and every later session opens already signed in.
Solari profiles use Playwright's storageState format, so a login exported from an existing Playwright script uploads as is.
The Solari Professional plan stores 500 profiles.
How Does Solari Reach Sources That Block Bots?
Solari stealth mode lets the browser browse like a real person, so sites don't flag it as a bot.
Solari proxies route a session through residential, static ISP or mobile IPs in 15 countries.
Solari solves captchas for $0.005 per solve on the Professional plan.
Solari bills proxy traffic at $4.00 per GB on the Professional plan.
How Does Recording Help Audit an Enrichment Run?
Solari records a session when it is created with recording turned on.
A recorded Solari session replays in the console or downloads as NDJSON, a line-by-line log of everything that happened on the page.
Solari keeps replays for 30 days on the Professional plan.
Recording captures input values by default, so run sign-in steps in a session without recording.
