Helicone
Pros
- + One-line proxy integration (change the base URL) is still the fastest instrumentation path I have used in this category
- + Apache-2.0 repo with commits still landing in October 2026 — the self-host hedge is real, not theoretical
- + Free Hobby tier (10,000 requests/month, 1 GB storage, one seat) is enough to fully instrument a side project or staging without a credit card
- + Gateway with fallbacks, caching, and custom rate limits plus observability in one hop; 0% markup claimed on provider credits
Cons
- - Acquired by Mintlify in March 2026 and in maintenance mode — no product roadmap, so plan a migration date regardless
- - Docs claim '$20/seat' while pricing sells a flat $79/month Pro plan; the information surface is drifting
- - Evaluation, tracing, and user tracking are self-described as limited versus dedicated platforms and will not improve now
- - Long-term hosting terms and end-of-life date are unpromised; consolidating provider billing through a departing team is a concentration risk
ChatGPT
Pros
- + Broadest multimodal surface in the category: text, reasoning, images, voice, video and agents in one subscription
- + Plus at $20/month is still the value anchor — my mixed weekly workload ran without visible caps
- + Deep research produced a 12-source competitive scan in about 8 minutes (two citation fixes needed, structure worth keeping)
- + GPT/connector ecosystem covers odd-shaped needs that no competitor matches
- + Business seat-type mixing (Standard + one Premium) is a sensible team pricing pattern
Cons
- - Free, Go, Plus and Pro conversations train models unless you opt out; no SOC 2 or SSO below Business
- - Caps downgrade silently to weaker models — quality drops without a warning
- - Ads now run on Free and Go in the US, including on a paid tier (Go)
- - Pro ladder ($100/$200/$500) buys capacity, not capability, with no annual discount anywhere in the lineup
- - Editing temperament drifts to confident verbosity; citations overreached sources in my deep research run
