Locus Pro vs treg: features, catalog and setup compared

Locus Pro and treg both give an AI agent one prepaid balance and one hosted MCP connection to paid APIs with no provider keys, so the choice comes down to catalog and controls. treg is the better pick for SEO, social, ads and GTM data, Chinese platforms such as Douyin, your own keys and connected accounts on any team, self-hosting, and a free $1.00 start. Locus Pro fits agents that also need OpenAI, Anthropic or Gemini models and ElevenLabs speech on one balance, a monthly hard spend limit, and customer billing later.

Choose treg if…

treg is the better choice in these cases.

Your agent mostly needs SEO, social, ads or GTM data, including Chinese platforms such as Douyin, Xiaohongshu and Weibo.
You already pay for some providers and want your own keys used first and unmetered, without an enterprise plan.
Your agent should work inside your own Google Analytics, Search Console or ad accounts.
Your team wants to share its own APIs, CLIs and skills behind one token, with roles and a tool allow-list for each member.
You want to start free. treg gives $1.00 of credit, and Locus Pro starts at a zero balance.
You don't want a plan to set your call rate. Locus Free allows 5 tool calls a minute and Plus allows 15.
You want to read the code or self-host it for your own organization.

Choose Locus Pro if…

Locus Pro is the better choice in these cases.

Your agent needs OpenAI, Anthropic or Gemini models on the same balance as its data tools.
You need ElevenLabs speech or Deepgram transcription.
You want hard limits on the account: a monthly cap that stops new calls, a max charge per call, and agent keys with per-run limits.
You want saved Workflows that run under a hard credit ceiling, with a receipt for every call.
You use Claude Code, Codex or Grok Build and want one plugin that adds the MCP connection and three skills.
You may bill your own customers per call later. Locus Pro for Platforms, on Enterprise, adds per-customer balances, your own prices and a billing widget, so you don't build invoicing yourself.

Can one agent use treg and Locus Pro together?

Yes. Both are hosted MCP servers, so one client can hold both connections. Tell the agent which to use for which job, for example treg for keyword data and social profiles, and Locus Pro for model calls and speech.

The two balances and their spend controls stay separate, so set a limit on each.
