Which one is for you?
The useful question is not which product is better. It is which of these two sentences describes your week:
- →"I need my agent to talk to a lot of services, and I don't want to build each integration." That is Composio's job. It describes itself as "Everything your agents need to take action," and states it offers 1,000+ integrations with delegated auth, sandboxed environments and parallel execution. You get an SDK, hosted MCP, triggers and a tool catalog, and you get moving in an afternoon.
- →"My agent can already reach the tools. I'm worried it will reach the wrong client's account." That is Outloop's job. It supplies no tool catalog. It governs which client account or resource a given workspace may use approved access against, keeps the credential in your own macOS Keychain, and denies a mismatched request before any call goes out.
Those are complementary problems, not competing ones. A team can genuinely have both, and a team that only has the first should not buy the second.
Honest capability comparison
Read this as "what each product takes responsibility for," not as a scorecard. Blank spaces are scope decisions, not gaps — neither product is trying to be the other.
| Dimension | Composio | Outloop |
|---|---|---|
| Core job | Integration + tool-calling platform: give agents a large catalog of pre-authenticated tools and run the calls | Runtime access layer: decide whether an agent may use approved access, for which client, against which resource |
| Integration catalog | States 1,000+ toolkits | — not its job; you connect the services you already use |
| Where credentials rest | Composio cloud by default; encrypted at rest (AES-256-GCM). VPC / self-hosting on Enterprise | macOS Keychain on your own Mac; read host-side at request time. No Outloop-hosted credential store |
| Agent sees the raw token | No — docs state credentials never pass through your app or the model; tokens redacted by default in API responses | No — the credential is used on the wire host-side; a redacted result is returned |
| Unit of separation | A userID your code supplies per call; plus organizations and projects, which isolate resources | A client workspace, pinned to a specific account or resource |
| Multiple accounts for one service | Documented default is the most recently connected active account, unless explicit selection is enabled | Explicit by construction — the workspace names the account; there is no implicit default |
| Wrong-client request | Connected accounts are private to their user and shared access is deny-by-default; the userID binding itself is asserted by your code | Denied by policy before any call reaches the provider |
| Runs where | Composio cloud; VPC / self-hosted on Enterprise | Your own Mac, local-first |
| Relationship to your vault | Composio stores the connected account | Sits above your existing vault — 1Password, Infisical, Doppler, Keychain |
| Billing unit | Tool calls (seats unlimited on paid tiers; connected accounts unlimited) | Client workspaces (not seats, not prompts, not calls) |
| Compliance posture | States SOC 2 Type II; marketing pages also cite ISO 27001:2022 | Makes no certification claim — see the honesty note below |
The agency scenario
Concretely: one agency, twenty clients. You hold a Google Ads manager account, a Meta Business portfolio, a set of client Shared Drives, and analytics access to twenty properties. Your team runs agents in several environments. Nothing about holding those credentials decides which client any given run should touch.
How this looks on Composio
You model each client as a user and pass its userID
when you create a session or execute a tool. Composio's docs recommend a stable identifier such as a
database primary key, warn against emails because they change, and warn specifically against shipping
"default" to production. Connected accounts
are private to their user unless you deliberately share them, and shared connections use an explicit
allow list evaluated deny-by-default. Organizations and projects isolate resources from one another.
Two details are worth reading carefully before you rely on this for client work. First, the mapping
from "this client" to "this userID" is
asserted by your own code on every call — we found no documented platform-side check that the identifier
you passed is the client you meant. Second, where one user holds several accounts for the same service,
Composio documents that the most recently connected active account is used automatically unless you
turn on require_explicit_selection. Both are
manageable; both are yours to get right.
How this looks on Outloop
The binding is the configuration rather than a call parameter. Each client gets a workspace, and that workspace is pinned to its own Google Ads customer ID, its own Meta ad account, its own Shared Drive, its own numeric GA4 property. An agent working in that workspace acts normally. A request naming a different client's resource is denied before any call reaches the provider, and both the allow and the deny are written to a redacted local audit.
That is the entire difference in one sentence: Composio gives you the means to separate clients correctly; Outloop makes separating them the default and a mistake the exception. Neither is automatically right — the second only matters if wrong-client access is a risk you are actually carrying.
The operating model
Composio is a service you call. Your agent asks Composio to execute a tool; Composio holds the connected account, performs the call from its infrastructure, and returns the result. That is what makes it fast to adopt — there is nothing to run.
Outloop runs on a Mac your company controls. The agent requests an approved action; a local broker checks the workspace, the service, the host and the resource, performs the call using a credential that never leaves the Keychain, and returns a redacted result with an audit entry. Nothing is hosted by us, which is a genuine cost as well as a benefit: you are running software on a machine you maintain.
Pricing
Composio
- →Free — $0. 20,000 tool calls/month, 3 team members, 1M LLM tokens, 7-day log retention.
- →Pro — $29/month. 50,000 tool calls/month, unlimited team members, custom tools and MCP, white-labeling.
- →Business — $599/month. Also 50,000 tool calls/month — it differentiates on features, not volume: self-managed credentials, IP allowlist, read-only dashboard role, higher rate limits, 90-day log retention. A DPA is a $500/month add-on.
- →Enterprise — custom. Adds VPC and self-hosting, ZDR availability, and an included DPA.
Overage is $4 per 1,000 tool calls, or $3 per 1,000 through Sessions. Connected accounts are unlimited on every tier — Composio states there is no limit on how many you can have — and team members are unlimited on paid tiers, so the meter is usage, not headcount. Raw proxy API requests bill at the same rate from the same allowance.
One thing to check for yourself rather than take from us: Pro and Business both list 50,000 tool calls per month on Composio's new pricing table. We read it several times and that is what it says, but the whole table is a day old, so confirm it before budgeting around it.
Outloop
Outloop prices by client workspace — reserved capacity, not metered calls or per-seat licences. Plans run from $79/month (5 client workspaces) to $899/month (100 client workspaces), with a custom tier above that. Full detail, including annual pricing, is on the pricing page.
The two models are hard to compare directly, which is itself informative. Composio's cost scales with how much your agents do; Outloop's scales with how many clients you separate. If you run enormous volume across a handful of accounts, usage pricing may well be cheaper. If you run modest volume across many client accounts, per-workspace pricing is more predictable. Model your own numbers — do not take a vendor's word for which shape suits you, including ours.
Who should choose Composio?
Genuinely, and without hedging — Composio is the better choice if:
- →You need breadth of integrations quickly and do not want to build or maintain them. This is the thing Outloop does not do at all.
- →You are building a product whose end users each connect their own accounts. Composio's hosted OAuth and per-user connected accounts are designed precisely for that shape.
- →You are happy with a managed cloud holding credentials, or you are large enough for the Enterprise VPC option.
- →You need a security certification on file today. Composio states SOC 2 Type II; Outloop claims none.
- →Your team is not on macOS, or you do not want to operate a machine of your own.
Who should choose Outloop?
- →You are an agency or operator running many client accounts through one agency identity — a Google Ads MCC, a Meta Business portfolio, client Drives — and the failure you fear is touching the wrong one.
- →You want credentials to stay on a company-controlled machine, above the vault you already run, rather than in a vendor's cloud.
- →You want the client boundary enforced as configuration, not asserted by whichever agent or prompt happens to be running.
- →You need a local, redacted audit of which client an agent actually touched — including the requests that were refused.
- →You want approved access reused across the agent runtimes your team already runs, instead of rebuilt per platform.
And if both descriptions fit, using both is a coherent answer. Composio can supply reach; Outloop can govern the client boundary on the systems where getting it wrong is expensive.
