What is Lago?
Lago is layering AI agents and enterprise gates onto an already-deep usage-based billing engine.
Lago is an open-source usage-based billing platform that has matured well past metering and into the full operational stack — entitlements, wallets, credit notes, e-invoicing, and analytics. Recent quarters have added an AI agent and MCP server for natural-language billing operations, ML-backed revenue forecasts, and the enterprise scaffolding (custom roles, security logs, audit-tracked communications) that procurement teams ask for. The wallet subsystem in particular is becoming a product of its own, with multiple wallets per customer, transaction limits, alerts, and full traceability of credit flows.
What is Stigg?
Stigg moves its entitlements and credit checks inside agent orchestrators and gateways.
Stigg now runs inside agent orchestration layers, applying entitlements, credits and budgets to each step of an agent run, and its Agent SDK supports solo.io and agentgateway out of the box. It also lets customers bill subscriptions through Airwallex invoices and payment links. This lands a day after new pricing with a free plan and monthly billing, and three days after Usage Governance went GA.

Lago
0.0FINANCE
Lago is layering AI agents and enterprise gates onto an already-deep usage-based billing engine.
◆ Current state
Lago is an open-source usage-based billing platform that has matured well past metering and into the full operational stack — entitlements, wallets, credit notes, e-invoicing, and analytics. Recent quarters have added an AI agent and MCP server for natural-language billing operations, ML-backed revenue forecasts, and the enterprise scaffolding (custom roles, security logs, audit-tracked communications) that procurement teams ask for. The wallet subsystem in particular is becoming a product of its own, with multiple wallets per customer, transaction limits, alerts, and full traceability of credit flows.
◆ Where it's heading
Lago is positioning itself as the billing backbone for AI-native and credit-economy products — pricing units, prepaid wallet primitives, and an MCP server are not generic SaaS billing features. In parallel it's pulling forward enterprise governance: roles, security logs, e-invoicing, granular API endpoints. The combination reads as a deliberate move upmarket, with the AI-billing angle as the wedge for new logos and the governance work as the ceiling-raiser for existing ones.
◆ Prediction
Expect more agentic surface (additional AI agent personas beyond the Billing Assistant, or MCP server hardening with action-confirmation flows), and continued e-invoicing jurisdiction coverage following the France template — Italy, Belgium, or another Peppol-aligned market would be the natural next stop.
Stigg
7.5FINANCE
Stigg moves its entitlements and credit checks inside agent orchestrators and gateways.
◆ Current state
Stigg now runs inside agent orchestration layers, applying entitlements, credits and budgets to each step of an agent run, and its Agent SDK supports solo.io and agentgateway out of the box. It also lets customers bill subscriptions through Airwallex invoices and payment links. This lands a day after new pricing with a free plan and monthly billing, and three days after Usage Governance went GA.
◆ Where it's heading
Stigg is placing its billing engine at the points where AI agents spend money: the orchestrator, the gateway and credit reservation before each operation. Billing-backend breadth, now Airwallex invoicing, keeps pace in the background.
◆ Prediction
Expect more gateway and orchestrator integrations in the Agent SDK and its move out of beta. Billing backends will likely keep widening around Airwallex and its peers.
