WebAI2API

WebAI2API converts web-based AI services (LMArena, Gemini, ChatGPT, DeepSeek, etc.) into OpenAI-compatible API endpoints. It uses browser automation via Camoufox to simulate human interactions, supporting multi-window concurrency, account isolation, and both text and image generation across supported platforms.

What WebAI2API is

Node.js/JavaScript application built on Camoufox (Playwright-based headless browser) that proxies web AI services through an OpenAI-compatible REST API. Features task queueing, load balancing, failover, streaming responses with keepalive heartbeats, and multi-instance browser isolation via configurable proxies. Provides VNC/Xvfb virtual display support for Linux/Docker environments.

Best use cases

Cost Arbitrage & Service Aggregation

Unified API access to multiple free/freemium AI services (Gemini, LMArena, DeepSeek) without maintaining separate client libraries or API keys. Useful for startups reducing inference costs or building multi-model fallback chains.

Browser-Based AI Integration Without Direct API Access

Services that only offer web interfaces (zAI, Nano Banana, Google Flow) can be bridged into backend systems expecting OpenAI-compatible endpoints. Enables legacy or restricted services to integrate into modern API-first architectures.

Multi-Tenant SaaS with Account Isolation

Browser instance-level data isolation and configurable per-proxy accounts allow SaaS platforms to manage multiple customer accounts or models under a single deployment, with per-user rate limiting and quota management.

Implementation considerations

Initial setup requires Node.js v20+, manual browser login for each account/adapter via VNC/Xvfb, and completion of any CAPTCHA or ToS flows. Plan 1–3 hours per account initialization.
Memory and CPU overhead scales with concurrent browser instances. Minimum 1 GB RAM for single instance; 4 GB+ recommended for multi-instance deployments. Headless mode trades resource efficiency for detection risk; headed mode (Xvfb on Linux) recommended.
Configuration via YAML (config.example.yaml → data/config.yaml) controls ports, auth tokens, concurrency limits, task queue depth, proxy routing, and adapter behavior. Changes require service restart.
Stream mode with keepalive heartbeats strongly recommended to prevent request timeouts during long inference. Non-stream requests rejected if task queue exceeds configured depth.
Adapter availability depends on target website stability and anti-bot defenses. No versioning or deprecation guarantee for broken adapters. Monitor GitHub issues and CHANGELOG for adapter updates.

When to avoid it — and what to weigh

You need guaranteed SLA or production-grade reliability — Reliance on web scraping and human-behavior simulation introduces inherent fragility. Service degradation, CAPTCHA loops, account bans, or UI changes can break adapters without warning. No formal SLA documentation or incident response process stated.
Your use case violates target websites' Terms of Service — README explicitly disclaims responsibility for account bans or other consequences. Most target sites prohibit automation. Automated account access to services like ChatGPT, Gemini, or DeepSeek may violate their ToS. Legal review required before deployment.
You require encrypted or air-gapped communication — README warns that WebUI transmission is unencrypted in public networks. Only SSH tunnels or HTTPS proxy recommended. No built-in end-to-end encryption for API payloads. Unsuitable for HIPAA, PCI-DSS, or similar compliance contexts.
You need fine-grained, real-time model/capability visibility — Adapter support and feature parity vary widely across target sites (text-generation, image-gen, video-gen marked as ✅/❌/🚫 with notes on watermarks, limitations). No structured capability matrix or SLA for feature availability.

License & commercial use

MIT License (permissive). Allows commercial use, modification, and redistribution with attribution. No copyleft or patent restrictions. See LICENSE file in repository.

MIT permits commercial use. However, the tool's core function—automating web scraping and account access to third-party services—likely violates ToS of target websites (ChatGPT, Gemini, DeepSeek, etc.). Use in production requires legal review and ToS compliance assessment. README explicitly disclaims responsibility for account bans or consequences. Insurance, indemnification, and liability clarity with end users required before commercial deployment.

Security considerations

WebUI and VNC lack encryption by default; SSH tunneling or HTTPS proxy required for public networks. Browser instances store credentials (cookies) in local filesystem; no encryption at rest documented. Multi-account isolation via browser instances reduces cross-account data leakage risk but relies on Camoufox/Playwright sandboxing (adequate for most use cases, not formal isolation). Input validation for model names and prompts not explicitly described. Account takeover, cookie theft, and detection/blocking by target sites are operational risks. Supply chain risk: depends on Camoufox (Firefox-based), Playwright, and third-party dependencies; no SBOM or security audit reported.

Alternatives to consider

LiteLLM / Ollama (local models)

Avoids web scraping risk by running open-source models (Llama, Mistral) locally or via API proxies. Trades cost arbitrage for higher upfront infrastructure and no access to proprietary models (GPT-4, Gemini 3).

Official APIs (OpenAI, Anthropic, Google Cloud Vertex AI, Together AI)

Guaranteed uptime, SLA, support, and legal compliance. Costlier than free/freemium web services. Best for production workloads where reliability and accountability are non-negotiable.

Native browser extension + proxy server (e.g., Puppeteer + custom proxies)

More granular control and isolation but requires custom development. Avoided by many teams due to maintenance burden; WebAI2API abstracts this but trades flexibility for integration convenience.

WebAI2API FAQ

Will my accounts get banned?

No guarantee. The README explicitly disclaims responsibility for account bans. Most target sites prohibit automation. Risk depends on detection sophistication, query patterns, and site ToS enforcement. Headless mode increases detection risk; headed mode (Xvfb/VNC) recommended.

How do I handle CAPTCHA or 2FA?

Manual intervention via VNC/Xvfb during initial login. Once session is established, keepalive logic attempts to maintain authentication. If accounts are logged out or challenged during operation, manual re-login via VNC is required. No automated CAPTCHA solving integrated.

Can I use this in production?

Not recommended without careful legal and operational review. ToS violations, fragile adapters, lack of SLA, and no vendor support make this suitable only for internal tools, research, or cost-optimized hobby projects. Production deployments require fallback to official APIs and documented ToS compliance.

What happens if a target website breaks my adapter?

You depend on the open-source community to publish fixes. GitHub issues show active engagement (1113 stars, 307 forks, 37 open issues), but no SLA. Significant UI changes or anti-bot upgrades can take days or weeks to patch. Monitor CHANGELOG and issues regularly.
