Willow automatically finds supported AI clients and local configuration files on managed devices, adds browser controls, and manages identities and background agents. systemprompt.io routes model and MCP traffic through a customer-run Rust platform with synchronous controls and customer-owned audit data.
Willow finds supported employee AI on managed devices and in supported browsers, then connects discovery to identity, policy, MCP access, and agent administration.
systemprompt.io is a source-available Rust platform customers deploy and operate for model routing, MCP enforcement, agent workflows, Skills, and audit.
Both provide private deployment, pre-execution controls, rate limits, identities, Skills, agents, and audit logs. Willow adds automatic device and browser discovery. systemprompt.io adds model routing and a source-available Rust codebase.
Compare what each product covers and what your team must operate.
| Willow | systemprompt.io | |
|---|---|---|
| Main job | Discover and govern employee AI across devices, browsers, identities, MCP access, and background agents | Run governed model, agent, and MCP traffic through customer-owned infrastructure |
| Before registration | Finds supported local MCP configurations, Skills, agent instructions, and installed AI tools | Registers agents, Skills, providers, and MCP servers configured in the platform |
| Runtime controls | Blocks or redacts tool inputs and outputs before delivery; also supports approvals, policy conditions, and per-user rate limits | Runs scope, scanner, blocklist, and token-bucket checks before connected tool execution |
| Model layer | Governs the tools AI clients can use rather than routing model requests across providers | Routes Anthropic, OpenAI, Gemini, Bedrock, Vertex, and compatible providers |
| Audit | Logs identity, access decisions, guard actions, tool calls, responses, tokens, and execution details, with export options | Stores prompt, response, identity, tool, token, and cost lineage in customer PostgreSQL |
| Operation | Managed SaaS plus hybrid, on-premises, and air-gapped deployment | Customer-run source-available Rust binary and PostgreSQL; no SaaS product |
| Extensibility | Admin configuration, APIs, connectors, guards, hooks, and custom MCP servers | Compile-time Rust extensions, jobs, routes, and MCP tools |
| Assurance | SOC 2 Type II | Framework control mappings; no independent SOC 2 or ISO 27001 certification |
Willow makes discovery and governance available through managed administration and existing device-management workflows.
Willow finds supported AI clients, local MCP configurations, Skills, CLAUDE.md, and AGENTS.md on managed macOS and Windows devices.
Prompt Guard checks messages and attachments in supported web AI chats. Claude Guard separately controls risky Claude-in-Chrome actions.
Willow combines SSO, groups, approved tools, self-service workflows, Skills, machine users, and background agents.
Willow offers SaaS, hybrid, on-premises, and air-gapped deployment instead of requiring every customer to operate the platform.
systemprompt.io gives engineering a Rust codebase, a built-in model gateway, PostgreSQL lineage, and compile-time extensions.
systemprompt.io is a source-available Rust platform that customers build, deploy, upgrade, and operate with PostgreSQL.
Connected MCP calls pass scope, scanner, blocklist, and token-bucket checks. Willow also blocks calls before execution, but uses configurable guards, policies, approvals, and rate limits.
The gateway routes several model providers and links model requests, identities, tool calls, tokens, and cost.
Engineering can add compile-time extensions, routes, jobs, and MCP tools, while owning their maintenance and upgrades.
We are six to ten months ahead of most companies in AI adoption. More code to production, fewer incidents, real outcomes. Willow is what made it possible to move that fast without slowing down our security posture.

Common questions from teams comparing Willow with systemprompt.io.
systemprompt.io manages Cowork deployments and agents, Skills, providers, and MCP servers registered with its platform. Willow automatically discovers supported local MCP configurations, Skills, agent instruction files, and installed AI clients before registration.
Yes. Willow applies identity checks, access rules, runtime guards, policy conditions, approvals, and rate limits. systemprompt.io uses a fixed pipeline of scope, scanner, blocklist, and token-bucket checks for connected calls.
Yes. Willow offers a fully on-premises deployment with no external runtime dependencies. systemprompt.io runs as a customer-operated Rust binary with PostgreSQL.
systemprompt.io. Customers run its source-available Rust platform and can add compile-time extensions, routes, jobs, and MCP tools.
No. It is source-available under BSL-1.1, which differs from an OSI open-source license.
No independent SOC 2 or ISO 27001 certification is listed. systemprompt.io provides control mappings for compliance frameworks.
