Cursor Alternatives in 2026: AI Coding With Your Own API Key
Cursor charges a subscription and reserves built-in model names, which makes bring-your-own-key setups fiddly. If you already have an API key, these five alternatives are cheaper (mostly free), more transparent about what they send, and often simpler to point at your own endpoint.
The comparison
| Tool | What it is | Cost | BYO-key setup |
|---|---|---|---|
| Cline | VS Code agent (plans, edits files, runs commands) | Free, open source | Excellent — native OpenAI-compatible option |
| Roo Code | Cline fork with more modes/personas | Free, open source | Excellent — same provider system |
| Continue | VS Code / JetBrains autocomplete + chat | Free, open source | Excellent — YAML config |
| Zed | Fast native editor with AI panel | Free editor | Good — settings.json OpenAI provider |
| Aider | Terminal pair-programmer, git-native | Free, open source | Excellent — two env vars |
Cline / Roo Code — the closest thing to Cursor's agent
Install the extension in VS Code → provider OpenAI Compatible → Base URL https://www.superbapi.com/v1, your sk-sbapi-… key, model claude-fable-5. Cline shows you every file edit and command before it runs — many devs find this more trustworthy than Cursor's opaque agent.
Continue — chat + autocomplete in the editor you already use
Add to config.yaml:
models: [{ name: Fable 5, provider: openai, model: claude-fable-5, apiBase: https://www.superbapi.com/v1, apiKey: sk-sbapi-… }] |
Works in VS Code and JetBrains IDEs — no editor switch needed.
Zed — if you want a faster editor too
Zed is a native-speed editor with an assistant panel. In settings.json, add an openai language-model provider with api_url: https://www.superbapi.com/v1, export your key, and pick the model in the assistant dropdown.
Aider — AI pair programming in the terminal
No editor integration at all: export OPENAI_API_BASE=https://www.superbapi.com/v1, export OPENAI_API_KEY=sk-sbapi-…, then aider --model openai/claude-fable-5. It edits your repo and makes clean git commits — ideal for refactors.
Still want Cursor?
It works with your own key too — the catch is Cursor reserves built-in ids like claude-fable-5, so use the sb- alias: add a custom model named sb-claude-fable-5, set the OpenAI base URL override to https://www.superbapi.com/v1, and turn other providers off.

Why bring your own key at all?
- One wallet, many tools — the same prepaid balance works in your editor, chat apps, and scripts.
- Per-key budgets — give each tool its own key with a monthly cap, so a runaway agent can't drain you.
- No per-seat subscription — free tools + pay-per-token often costs less than an IDE plan you underuse.
