Ofcors vs Insomnia
Insomnia is a capable API client and design tool from Kong, with scripting, mocks and a CLI. Ofcors is a native app for hands-on API work that needs no account for anything, built around gRPC, flows, AI endpoints and MCP servers.
inso CLI's test reports in CI.Ofcors doesn't do these yet. If they're central to your work, Insomnia is the better tool today.
| Ofcors | Insomnia | |
|---|---|---|
| Account | Not needed for anything. | Only the Scratch Pad works signed out; local projects, sync and mocks need a free account. Source |
| Where your work lives | A file in your app data folder, or plain YAML files in a project folder in your repo, one per request. Secret values stay in your keychain. | Your choice of Local Vault, end-to-end encrypted Cloud Sync, or Git Sync. Source |
| Open source | No. | Yes, Apache-2.0. Source |
| Secrets | In your OS keychain. | Encrypted locally with a vault key; external vaults on Enterprise. Source |
| Protocols | REST, GraphQL, gRPC, server-sent events, MCP. | REST, GraphQL, gRPC, server-sent events, MCP, WebSocket, Socket.IO, SOAP. |
| gRPC protos | Fetched from your proto repo and kept in sync (Buf workspaces too), FieldMask picker, warnings when the server sends fields your protos don't define. | Server reflection, uploaded .proto files or folders, or the Buf Schema Registry. Source |
| AI chat endpoints | Chat view: replies streamed from OpenAI, Anthropic and Vercel AI SDK formats, with time to first token and tokens per second. | Server-sent events shown as they arrive. |
| Chaining and checks | Flows: steps use earlier responses ({{step1.id}}), with checks, repeats, inputs, and script steps in Python, JavaScript, Ruby, Bash or any command. A notebook or a canvas. |
JavaScript scripts and tests, and a collection runner. Source |
| CI, mocks, API design | The ofcors command runs flows and requests in CI. Mocks and an API design editor: not yet. |
inso CLI, cloud or self-hosted mocks, OpenAPI editor with linting. Source |
| The app | Native: a Rust core in a Tauri shell. | Electron. Source |

Not in one click yet: Insomnia exports its own YAML format and HAR, not Postman collections, and Ofcors doesn't read those yet. You can copy any request as cURL in Insomnia and paste it into Ofcors's URL bar. An Insomnia importer is on our list.
Yes. Ofcors needs no account and keeps your work on your machine, so it can sit next to Insomnia for gRPC, flows, MCP servers and AI endpoints.
No. Ofcors is free to use with no tiers for local work; a paid Team plan for live shared workspaces is coming. If an open-source licence matters to your team, that's a point for Insomnia.
No. Ofcors is an independent product. Insomnia is a trademark of Kong Inc.
