BYO-Key Coding Stack
Run a serious AI coding setup without subscription markups. Cline as the open-source agent in your IDE, OpenRouter as the model router so you switch frontier models per task, and Firecrawl when the agent needs to read live docs.
Why these tools work together
Most coding agent setups bundle the editor, the agent, and the model billing into one fixed-price subscription. That is fine until you want to use Claude on hard problems, GPT on cheap tasks, and a local model on privacy-sensitive code. This stack splits the layers: Cline is the free open-source agent, OpenRouter is the model router that lets you pay per token across providers, and Firecrawl plugs in when the agent needs the live web. You only pay for tokens you actually consume, and you keep optionality on which model handles which task.
How it works
- 1
Create one OpenRouter key, fund it with a small balance, and configure Cline to use it as the provider
Single key that unlocks Claude, GPT, Gemini, and others without separate subscriptions
- 2
Open Cline in your editor, switch to Plan mode, and describe the change you want
A markdown plan you can edit before any code is written
- 3
Connect Firecrawl as an MCP server so the agent can fetch live documentation when needed
Up-to-date context pulled straight into the agent's working memory
- 4
Switch to Act mode and let Cline execute the plan, approving file edits and shell commands as it goes
Working code changes with checkpointed rollback if anything goes off-track
Tools in this stack
Open-source AI coding agent inside VS Code or JetBrains, with Plan and Act modes
An open-source AI coding agent that runs inside VS Code, JetBrains, and a CLI, with bring-your-own-key inference so you only pay for the model tokens, not a subscription.
One API key that routes to Claude, GPT, Gemini, and dozens of other models with transparent per-token pricing
Unified API gateway giving access to 300+ language models across 60+ providers including GPT, Claude, Gemini, and Llama, with automatic fallbacks, smart provider routing, and cost optimization.
Alternatives: anthropic-direct, openai-direct
Web scraping API the agent calls via MCP when it needs current docs, examples, or API references
A developer-first web scraping and crawling API that converts any webpage into clean, LLM-ready markdown or structured data. Built specifically for feeding web content into AI agents, RAG pipelines, and data extraction workflows.
