Pricing

Cline is free and open source. You pay only your model provider (Anthropic, OpenAI, etc.) for API usage. No hosted service, no markup. Decalyst adds hosted infrastructure and security scanning bundled in credits; you pay $1 for 500 credits which covers both inference and Decalyst's platform.

BYOK and key handling

Cline requires BYOK; you configure your API key in VS Code settings or environment variables. Cost is direct to your model provider with zero markup. Decalyst also supports BYOK (zero markup) but adds optional managed billing. Cline gives you maximum transparency; Decalyst adds convenience if you do not want to manage keys.

Local vs hosted models

Cline has excellent support for Ollama, LM Studio, and other local models via its model selection interface. You can run code generation entirely on-device. Decalyst runs embeddings locally but generation on DigitalOcean inference, prioritizing speed and multi-GPU scaling.

Security review on every diff

Cline has no built-in security scanner. Decalyst includes a mandatory 20-point security scanner on every diff, covering injection, XSS, secrets, and more. For security-first workflows, Decalyst scans automatically; Cline requires manual review.

IDE depth and architecture

Cline runs inside VS Code as an extension, so you get all VS Code functionality, themes, and extensions. Decalyst is a standalone native desktop app (Tauri 2 + Monaco) that does not depend on VS Code. Cline is lighter and familiar to VS Code users; Decalyst is independent and portable.

Telemetry and privacy posture

Cline is open source on GitHub with no telemetry by default. Your keys and prompts are completely transparent. Decalyst is commercial with opt-in telemetry. For maximum privacy and auditability, Cline (especially with local models) is superior; Decalyst is still privacy-respecting and opt-in only.

When to pick which

Pick Cline if you live in VS Code, want auditable open-source agent code, and are comfortable managing API keys. Pick Decalyst for a standalone native IDE, automated security scanning, and team collaboration without key management overhead.
