AI Coding Assistant Rate-Limit Forecaster And BYOK Failover Bridge For Individual Paid Copilot, Cursor, And Windsurf Users

dev tool real project ••• trending

Pro+ Copilot subscribers are getting 5-day weekly lockouts at 25-35% of their monthly quota because GitHub silently changed the multipliers (Opus 4.7 = 15x) and the meter is not visible inside the IDE. Cursor and Windsurf hit the same anxiety wall after their 2025-2026 credit conversions. Devs want a sidebar widget that estimates the cost of the next prompt before they click run, shows the curve of when they'll hit the wall at the current pace, and auto-fails-over to their personal OpenAI/Anthropic API key when the meter passes a configurable threshold. Different audience from manager-level org spend tools... this is for the individual paying $39/mo who needs the assistant to keep working past Tuesday.

builder note

The vendor-relations trap is obvious... GitHub will not love you. The defense is to position this as 'spillover insurance' not 'arbitrage'. Bill it $5/mo, store no prompts, route only the overflow. Distinct from the manager-tier spend gateways already on market: this is the dev's personal pager, not the CFO's dashboard.

Vendors won't ship this... a forecaster that helps you stop paying them is anti-aligned with their pricing strategy. OpenRouter and LiteLLM solve half (BYOK routing) but skip the IDE-side meter. The unmet need is a single VSCode/Cursor/JetBrains plugin that does both.

OpenRouter BYOK proxy but does not integrate with Copilot's or Cursor's IDE binding. You have to manually switch your editor to the OpenRouter endpoint, which loses Copilot's PR/repo-aware features.

LiteLLM Multi-LLM proxy with budgets, but it's a self-hosted server-side thing aimed at platform teams. Individual devs are not going to stand it up.

Copilot's own usage page Static, refreshes slowly, does not show the per-model multiplier, does not predict when you'll hit the weekly wall, and gives no in-IDE warning until you've already been cut off.

Cursor usage modal Shows current credit balance but does not project burn rate against your typical session pattern, and has no failover mechanism if you do go over.
