Solwyn Docs
SDK-first control plane for AI agents — hard spending caps, automatic provider failover, and per-agent cost attribution, without ever seeing your prompts.

Three lines wrap OpenAI, Anthropic, Gemini, Bedrock, or Together. → Quickstart

Alert-only by default; hard-deny is one flag. → Budget enforcement
Running coding agents? The CLI gives them pre-flight budget guardrails to call before they spend — reserve, spend, settle. → Agent integration

Quickstart
From pip install to a tracked call in your dashboard — about five minutes.
Providers
OpenAI, Anthropic, Google Gemini, Amazon Bedrock, Together AI, and any OpenAI-compatible endpoint.
Budget enforcement
Alert-only vs hard-deny, and what happens when you hit the limit.
Run control
Stop a runaway agent from the dashboard, or let the SDK's velocity detector stop it locally.
Framework integrations
Tested recipes for OpenAI Agents, LangChain and LangGraph, and CrewAI.
Testing
Script denials, outages, and kills against a zero-network control-plane double.
Privacy & how it works
The exact wire contract — token counts and metadata, never prompts or responses.
CLI
Budget guardrails for agents, cost monitoring for humans — from the terminal or over MCP.
Dashboard guide
Signing up, where everything lives, and how to recover access.
Cloud & dashboard
Get your API key, watch spend, and receive signed webhooks for budget events.
