treg vs Composio: the short answer
Both give an agent tools through one MCP server, with your own keys welcome. treg is like OpenRouter for tools: one API key and one balance for many paid APIs. treg gives your agent paid data from 4,100+ tools across 126 providers with no vendor accounts, at 0% markup, and your own keys and connected accounts are never metered. Composio connects your agent to 1,000+ apps (Gmail, Slack, Salesforce, HubSpot) so it acts inside each user's own accounts, with managed OAuth and triggers. Many agents use both: Composio for the app actions, treg for the data.
Which one fits
Different tools fit different jobs. Here is when each one is the better choice.
Choose Composio if
- Your agent acts inside many SaaS apps for each of your end users.
- You need triggers, so the agent reacts to events in those apps.
- You are building a multi-user product, with white-labeled OAuth and per-user accounts.
- You make very many app calls: 100,000 free a month, then from $0.0003 each.
- You need SOC 2 Type II, BAA or zero data retention options.
Choose treg if
- Your agent needs keyword volume, backlinks, work emails, social profiles, ad libraries or image and video generation, with no account at each vendor.
- You want each call billed at the provider's own rate from a prepaid balance, with no plan and no seats.
- You want your own provider keys to win over treg's and never be metered.
- You want Google Analytics, Search Console, Google Ads, Meta Ads, LinkedIn and Slack on the same token, never metered.
- You want to self-host for your team from the code on GitHub.
