Pricing & Plans

The core serial terminal: port connection & configuration, data buffer with ASCII/HEX modes, macros (M1–M6), MCU programmer (ESP8266/ESP32/STM32/AVR), logging, themes, and multi-language support.

BYOK stands for Bring Your Own Key. Instead of buying AI credits from ComIO.Studio at a markup, you connect the app to your own AI provider account. The app routes assistant requests through that provider, and you pay the provider directly under their pricing — no per-token billing through ComIO.Studio, no resold AI credits.

Supported BYOK routes:

• an OpenRouter API key (one key, hundreds of models),
• a locally installed Claude Code CLI (signed in with your Claude account),
• a locally installed Codex CLI (signed in with your ChatGPT account).

The app does not accept raw OpenAI or Anthropic API keys directly — supported routes are OpenRouter or the official CLI agents listed above.

Beyond BYOK, ProBaud also includes a fully local LLM engine — it runs entirely offline on your own machine, with no API key, no provider account, and nothing sent to any third party.

ProBaud (BYOK) is the paid plan that unlocks advanced features in ComIO.Studio: Triggers (pattern-based auto-respond rules), Lua scripting for automation, and the AI assistant. On the AI side you can run a fully local LLM offline (no key, no account, nothing leaves your machine), or use BYOK (Bring Your Own Key) to connect your own provider — an OpenRouter API key (one key, hundreds of models) or a locally installed CLI agent (Claude Code or Codex). The app does not accept raw OpenAI or Anthropic API keys directly. You pay your provider for AI; ComIO.Studio does not resell AI credits. The subscription ($3.90/mo, $39/yr, or $99 lifetime) unlocks all ProBaud features in the app.

Yes — the ProBaud (BYOK) plan includes a 7-day free trial. To use the AI during the trial you'll need to set up your provider: an OpenRouter API key, or Claude Code / Codex CLI installed on your machine.

For $3.90/month, you get access to all ProBaud features in the app — Triggers, Lua scripting, and the AI assistant feature. The subscription renews automatically every month and is billed each cycle until you cancel — you can cancel at any time and keep access until the end of the paid period. The AI side requires your own AI provider (OpenRouter key or Claude Code / Codex CLI), which has its own separate pricing set by that provider. AI service availability depends on that provider — ComIO.Studio does not control or guarantee third-party AI service continuity.

For $39/year, you get access to all ProBaud features in the app — Triggers, Lua scripting, and the AI assistant feature — at a 17% discount compared to monthly. The subscription renews automatically every year and is billed each cycle until you cancel — you can cancel at any time and keep access until the end of the paid period. The AI side requires your own AI provider (OpenRouter key or Claude Code / Codex CLI), which has its own separate pricing set by that provider. AI service availability depends on that provider — ComIO.Studio does not control or guarantee third-party AI service continuity.

For $99 one-time, you get long-term access to all ProBaud features in the app — Triggers, Lua scripting, and the AI assistant feature — without any recurring ComIO.Studio subscription. The AI side requires your own AI provider (OpenRouter key or Claude Code / Codex CLI), which has its own separate pricing set by that provider. AI service availability depends on that provider — ComIO.Studio does not control or guarantee third-party AI service continuity. The lifetime license may be limited to specific major versions as indicated at activation.

Yes. You can upgrade, downgrade, or cancel at any time. Changes take effect at the start of your next billing cycle. No long-term contracts.

Payments are processed securely through Lemon Squeezy (our merchant of record), which handles billing and applicable taxes. ProBaud is available as a monthly, yearly, or one-time lifetime purchase, with a 7-day free trial.
