You will get LLM Gateway with built-in observability, cost optimization and tracking
Project details
Costbase is an intelligent LLM gateway built for teams that are serious about AI cost control.
Most engineering teams overpay for LLMs because they default every request to an expensive flagship model, have no caching layer, and can't attribute costs to customers or teams. Costbase solves all three.
It works as a drop-in replacement for the OpenAI SDK, change one line of code, point your base URL to Costbase, and intelligent optimization kicks in immediately. Under the hood, it analyzes every request and routes it to the cheapest model that can handle it, semantically caches similar queries so repeated questions cost near zero, and gives you granular cost breakdowns by user, tenant, or project.
Unlike API resellers, Costbase uses your own API keys... you pay providers directly, keep your rate limits and enterprise discounts, and Costbase adds zero per-token markup.
What it does:
• Intelligent routing across 114+ models from 8 providers
• Semantic caching (similar queries served instantly at near-zero cost)
• Per-tenant/use-case cost attribution
• PII/PHI detection and masking
• Budget controls
• Automatic failover in under 100ms
• Real-time analytics, webhooks, and team RBAC

Softr Developer: Tweak project started with SOFTRAI, to create landing pages based on form
Great work again, built complex system in "no code" space but quite capable of complex coding solutions as well.
