Cachely is the managed self-hosted remote cache for Nx and Turborepo - the cache backend you'd otherwise build and run yourself, hosted for you on Cloudflare's edge (R2). It's a drop-in replacement for a DIY @nx/s3-cache / S3 bucket setup: point your build tool at Cachely with a token and two environment variables, and share build cache across CI and every developer's laptop.

Unlike a self-hosted cache, Cachely enforces read-only tokens at the API, so pull-request and fork builds can read but never write - closing the Nx cache-poisoning attack (CVE-2025-36852). It adds ROI reporting (the real build minutes and dollars the cache saved), per-tool insights, and build-optimization suggestions on top.

Pricing is a flat per-workspace subscription with no per-seat fees - add every developer, bot, and CI actor without watching the bill. Cachely never stores your source code; it caches only task outputs and their content hashes. Nx and Turborepo today; Bazel on the roadmap.

Opportuna is a real-time cryptocurrency arbitrage platform that helps traders spot profitable price differences across 12+ exchanges - without needing API keys or coding skills.

What We Do

We monitor live price data across major exchanges including Binance, Bybit, OKX, KuCoin, and more, surfacing two types of arbitrage opportunities:

  • Spot arbitrage: buy crypto cheaper on one exchange, sell higher on another
  • Funding rate arbitrage: profit from spreads between spot and perpetual markets

Key Features

  • Real-time scanner: live price updates, not delayed or historical data
  • Smart filters: filter by exchange, profit threshold, volume, and transferability
  • No API keys required: works out of the box, no complex setup
  • Mobile-optimized: full functionality on any device
  • Free tier: full scanner access with no credit card required
  • Guest preview: browse live opportunities without signing up

Why Opportuna?

Most arbitrage tools either require API keys, limit you to a few exchanges, or show stale data. Opportuna is built for traders who want to find opportunities fast without spending hours configuring tools or manually checking exchanges

As answered by people managing Cachely.dev and Opportuna.

What makes your product unique?

Opportuna's answer:

Opportuna combines real-time data, multi-exchange coverage, and zero setup friction in one platform. Unlike competitors that require API keys or limit you to a few exchanges, Opportuna monitors 12+ exchanges out of the box with live updates. We also cover both spot arbitrage and funding rate arbitrage in a single dashboard, and offer a genuinely useful free tier - no credit card, no API setup, just open and start scanning.

Opportuna's answer:

Three reasons: (1) No API keys required. Works immediately without connecting your exchange accounts (2) Real-time data. Not delayed or historical snapshots (3) Free tier with full scanner access.
