A side-by-side comparison of HarnessRouter and Prava — 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
Prava

Key features
- PCI-Compliant Card & Wallet Access: Provides infrastructure to enable card and wallet payments that adhere to PCI compliance standards so agents can transact securely.
- Built-in Financial Guardrails: Offers configurable controls (limits, restrictions, and policies) that prevent unsafe or unauthorized autonomous spending by AI agents.
- Agentic Commerce API: Exposes endpoints designed for AI agents to request, authorize, and execute purchases programmatically, enabling end-to-end agent-driven transactions.
- Fast Integration: Advertises a minimal-install integration flow ("Integrate in 4 lines") to help developers add agent payment capabilities quickly.
- Regional Support: Focused operational support for transactions across the United States and Southeast Asia, enabling geo-aware flows and merchant coverage.
- Developer Documentation & GitHub Presence: Public docs and repository presence (Prava-Payments GitHub) to help developers implement and test integrations.
- Payments API for autonomous agent purchases with PCI-compliant card and wallet access
- Built-in financial guardrails and regional support targeting US and Southeast Asia
- Quick integration claim ("Integrate in 4 lines") and public docs
- Prava SDK (Controls API) for digital labor and looped agent workflows driven by screenshots
- Pretrained models: prava-af-medium (general automation) and prava-quick-click (fast/simple automation)
- Standardized action types: left_click, type, key, scroll, wait, stop
- Client examples and integration helpers for Playwright, PyAutoGUI, TypeScript, and Python
- API key based authentication and example-driven documentation in GitHub repos
Best for
- Autonomous Shopping Agents: Allowing an AI shopping assistant to select items and complete purchases on behalf of a user while enforcing spending limits and merchant restrictions.
- Virtual Assistant Bookings: Enabling virtual assistants to book travel, event tickets, or subscriptions by executing payments directly with stored card or wallet access.
- SaaS Platforms Delegating Payments: Letting SaaS apps delegate low-risk payments to automated workflows (billing third-party services or procuring software licenses) under guardrails.
- Marketplace Agent Checkout: Allowing agent-driven checkout flows in marketplaces where agents finalize orders and handle payment authorization and receipts.
- Regional Commerce Services: Supporting businesses operating in the US and Southeast Asia to enable agents to transact in region-specific merchant and regulatory contexts.
- Enable AI agents to complete purchases autonomously within apps and web stores
- Integrate payments into agent-driven commerce workflows with guardrails and wallet support
- Automate repetitive GUI tasks and end-to-end digital workflows using screenshot-driven agent loops
- Build agent assistants that propose actions, execute them (via Playwright/PyAutoGUI), and iterate
- Rapid prototyping of automation flows using provided SDK models and example code
