A CLI tool that caps and halts AI coding spend before a session blows the budget
Individual developers and small teams using Cursor, GitHub Copilot, Windsurf, and Claude Code on usage-based billing have no way to enforce a hard spending ceiling before a session starts. Enterprise AI gateways (Bifrost, Maxim, Waxell) exist but require IT provisioning, virtual-key proxy routing, and team dashboards, making them impractical for a solo dev or a 3-person startup. This CLI tool runs locally, tracks cumulative token spend across all AI coding tools in real time, and blocks a new session from launching if the user's per-session, per-day, or per-repo budget cap is already met. It provides model-multiplier-aware cost estimation (e.g., Sonnet 9x Haiku, Opus 27x Haiku) so the developer sees projected cost before the first token is sent, not after the bill arrives.

Gap Assessment
4 tools exist (Bifrost AI Gateway, Maxim AI, Waxell, GitHub Copilot built-in spend controls) but gaps remain: Requires enterprise IT setup and key re-routing through a cloud proxy; no local CLI install; no pre-session project or per-repo cap; no model-multiplier cost estimator before session launch; not designed for solo devs or small teams; Monitoring and alerting only; does not block a session before launch; no hard pre-session ceiling; no cross-tool aggregation across Copilot + Cursor + Windsurf in a unified local CLI.

Competitive LandscapeFREE
| Product | Does | Missing |
|---|---|---|
| Bifrost AI Gateway | Enterprise AI gateway that issues virtual keys per developer with per-day/week/month dollar caps; supports Claude Code, Codex CLI, Cursor via key re-routing through a proxy; hard blocks requests when budget is exhausted | Requires enterprise IT setup and key re-routing through a cloud proxy; no local CLI install; no pre-session project or per-repo cap; no model-multiplier cost estimator before session launch; not designed for solo devs or small teams |
| Maxim AI | AI observability and spend tracking for coding agents; tracks spend across Claude Code and Codex CLI sessions; provides dashboards and alerts | Monitoring and alerting only; does not block a session before launch; no hard pre-session ceiling; no cross-tool aggregation across Copilot + Cursor + Windsurf in a unified local CLI |
| Waxell | AI agent token budget enforcement layer; intercepts API calls and terminates sessions when a ceiling is crossed; enterprise middleware | Requires API proxy setup; no local developer CLI; no per-session pre-launch block; no model-multiplier estimator; no native multi-tool aggregation for Cursor + Copilot + Windsurf |
| GitHub Copilot built-in spend controls | Enterprise admin can set monthly credit budgets per organization seat; post-exhaustion the assistant stops serving expensive requests | Admin-only dashboard controls, not developer-facing CLI; post-hoc exhaustion not a pre-session block; Copilot-only with no aggregation across Cursor or Windsurf; no model-multiplier estimator |
