Build a hosted LLM context compression proxy
The Problem
AI agents generate thousands of noise tokens in context windows, spiraling inference costs for developers building production apps. LiteLLM and similar proxies introduce high latency (noticeable in benchmarks) and struggle beyond moderate RPS, lacking scaling for agent workloads. Developers currently spend on observability tools like Helicone ($20+/month) or enterprise gateways without compression, failing to address token bloat directly.
Core Insight
Hosted proxy with automatic context compression for noise-heavy agent inputs, plus intuitive dashboard for real-time metrics—fills gaps in competitors' lack of compression (e.g., no native reduction in Portkey/Helicone) and prototype-only scaling (LiteLLM), delivering 50%+ token savings like Edgee but simplified for solos.
- Target Customer
- Indie hackers and solo founders building AI agents (e.g., using LangChain), part of the growing 100k+ AI developer community seeking cost-optimized proxies; market for LLM gateways exploding in 2025 with production AI apps.
- Revenue Model
- Freemium: free tier for <10k requests/month (matching Helicone), pro at $29-49/month for unlimited compression/dashboard (undercutting Portkey's $49), plus usage at $0.0001-0.0002 per 1k tokens.
Competitive Landscape
Usage-based; pay per compressed token, specific tiers not detailed in sources but offers cost governance alerts.
While Edgee offers token compression achieving up to 50% input token reduction, it lacks a dedicated dashboard for monitoring compression metrics and lacks explicit hosted proxy simplicity for indie hackers deploying AI agents. No mention of specialized context window management for noise-heavy agent workflows.
Freemium with paid plans starting at $49/month for pro features, enterprise custom pricing.
Portkey focuses on enterprise-grade observability, governance, and 1600+ LLM connections but does not provide built-in context compression, leading to higher token costs in long-context agent scenarios without manual optimization.
Free tier up to 10k requests/month; paid starts at $20/month for 100k requests, then $0.0002 per extra request.
Helicone excels in production-grade observability and caching but misses native LLM context compression, forcing users to handle noisy token inputs from AI agents manually, which spirals costs.
Open-source core free; enterprise managed version with custom pricing for production.
Bifrost provides high-performance routing with semantic caching and low latency (11µs overhead) but lacks specific context compression for reducing noise tokens in AI agent contexts, missing a dashboard for compression analytics.
Managed service; starts at custom enterprise pricing, no public free tier detailed.
TrueFoundry offers low-latency gateway (3-4ms) with traffic routing and observability but no built-in context compression, inadequate for token-heavy AI agents where noise tokens drive up costs without reduction tools.
Willingness to Pay
- Up to 50% token cost reduction
Edgee compresses prompts to reduce token usage by up to 50%, lowering costs—especially valuable for long contexts, RAG pipelines, and multi-turn agents.

- Enterprise managed service pricing (implied shift from free LiteLLM to paid)
TrueFoundry AI Gateway delivers ~3–4 ms latency... production-ready, while LiteLLM suffers from high latency... best for light or prototype workloads.
