HarnessRouter vs Suprbox — Secure Storage for Autonomous AI Agents: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of HarnessRouter and Suprbox — Secure Storage for Autonomous AI Agents — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
HarnessRouter
HarnessRouter
One API to run Codex, Claude Code, Hermes and other coding agents as your product backend — Y Combinator backed.
Key features
- Unified Agent API: Route to Codex, Claude Code, Hermes, Pi and other coding/autonomous agents through one endpoint
- Managed Runtime: Per-run sandbox, sessions, streaming, retries, timeouts, and permissions handled for you
- Artifact Delivery: Agents return files, code, videos, documents and other real artifacts to end users
- Execution Tracing: Step-by-step event timeline with tool calls, file changes, and agent messages for every run
- Per-Harness Settings: Configure model, tools, MCP, skills, and guardrails per harness
- Cost Controls: Budgets, alerts, and hard caps so production usage stops at your limit not your bill
- MCP Support: Bring your own MCP servers and skills into each harness
- Auto Upgrades: Platform handles upgrades, fixes, and maintenance of the agent runtimes
Best for
- Ship a website or app builder where users describe a product and get generated code/media
- Embed a digital employee that runs long-running tasks inside your SaaS
- Build model evaluation, legal, ops, or planning agents backed by frontier coding models
- Add an AI feature that produces videos, games, docs, or codebases as artifacts for end users
- Skip building sandboxing, streaming, retries, and permissions in-house
- Give internal teams a governed way to run Codex or Claude Code against production data
- Deploy an agent backend with production credits and hard cost caps
Suprbox — Secure Storage for Autonomous AI Agents
Suprbox
Secure, purpose-built memory fabric that mediates document access and stores context and recall vectors for autonomous AI agents.
Key features
- Purpose-Built Memory Fabric: Provides a dedicated storage layer for agent context and state, optimized for storing and recalling contextual information used by autonomous agents.
- Vector Recall & Retrieval: Stores recall vectors and supports fast retrieval of context vectors so agents can access relevant context quickly during execution.
- Document Gateway: Sits between documents and agents to mediate reads and writes, preventing direct, uncontrolled agent access to source documents.
- Runtime Policy Enforcement: Enforces tight, fine-grained policies at execution time to control what agents can read, write, or execute against stored data.
- Execution Isolation: Isolates agent workspaces and memory to reduce risk of cross-agent data leakage and maintain separation between concurrent agent sessions.
- Controlled Context Delivery: Supplies agents only the allowed slices of context and vectors needed for a task, limiting exposure of sensitive information.
- Interposes between documents and autonomous agents to control access
- Purpose-built memory fabric for storing agent context and recall vectors
- Policy-driven execution and enforcement for agent operations
- Workspace isolation to prevent cross-agent data leakage
- Access controls and document-level gating for agents
- Designed for auditability and runtime visibility of agent access patterns
- Integrates with agent workflows to mediate reads/writes to storage
Best for
- Protecting enterprise document stores from autonomous agents by mediating agent access and preventing unauthorized reads of sensitive files.
- Providing persistent agent memory for multi-step workflows where agents need to store and recall contextual vectors across sessions.
- Enforcing runtime access policies for agents operating in regulated industries (finance, healthcare, legal) to maintain compliance and governance.
- Powering secure Retrieval-Augmented Generation (RAG) pipelines where agents retrieve vetted context vectors rather than raw documents.
- Isolating agent workspaces for research or development teams to experiment with agent behaviors without risking cross-project data leaks.
- Coordinating multi-agent systems by centralizing shared context and controlling which agents can access which pieces of memory.
- Prevent autonomous agents from reading or exfiltrating sensitive documents
- Store and manage agent context and memory vectors securely
- Enforce runtime policies for agentic workflows (who/when/how data is accessed)
- Isolate agent workspaces to reduce risk of data bleed between agents
- Provide a secure intermediary for LLMs and bots accessing corporate documents
