Thermoptic is a stealth HTTP proxy that routes requests from any HTTP client (like curl) through a containerized Chrome instance so the traffic is indistinguishable from a real Chrome browser at every layer, including JA4+ TLS and HTTP fingerprints. It also offers hooks to mitigate JavaScript-based fingerprinting and supports hybrid scraping that mixes browser sessions with low-level HTTP clients.
Use cases
- scrape sites that block curl via JA4+ or Cloudflare fingerprinting
- make curl requests look like real Chrome traffic
- continue a browser session with a low-level HTTP client without detection
- bypass TLS and HTTP client fingerprinting blocks
- avoid JavaScript-based bot fingerprinting while scraping
- run hybrid browser and HTTP-client scraping pipelines
When to choose
- you need your HTTP client traffic to match a real Chrome fingerprint exactly
- anti-bot services like Cloudflare block your scraper based on JA4+ fingerprints
- you want to switch between a real browser and curl within one session without being flagged
When to avoid
- you need a general-purpose proxy unrelated to fingerprint evasion
- your target blocks you by IP reputation rather than client fingerprinting
- you cannot run a containerized Chrome instance or lack the resources for it
