Surfil

Surfil provides an on-device control plane for various coding assistants, enhancing their performance and security. Key features include: * Reduced token usage for coding agents * Blocking of risky or unauthorized calls * Ensuring source code remains on your machine * Offline-verifiable receipts for all transactions * Integration with popular coding tools like Claude Code, Cursor, Codex, and Copilot This robust system functions as a unified interception point, streamlining interactions with multiple coding helpers. It significantly cuts down on token expenditure by consolidating requests, leading to more cost-effective development cycles. Furthermore, Surfil prioritizes data privacy and security by preventing source code from leaving your local machine, and by blocking potentially dangerous API calls. Surfil offers transparent operations through byte-exact processing and verifiable receipts. Every claim made by the platform is backed by an Ed25519-signed receipt, allowing users to verify operations offline against a public key, without needing an account. This level of auditing ensures trust and accountability in managing your coding agent interactions. Ideal for software developers, engineering teams, and anyone utilizing multiple coding assistants who require enhanced security, cost optimization, and full control over their code's interaction with external services.
