About Respan AI
Respan is an LLM engineering platform and API gateway for routing, observing, evaluating, and optimizing large language model calls.Route traffic to 500+ models with OpenAI-style API compatibility, provider passthrough, model fallbacks, load balancing, retries/backoff, and per-key spend controls.

Capture every request as a trace tree with latency spans, metadata, and session context to reproduce and inspect real production sessions.Monitor usage and performance with dashboards that slice metrics by model, user, key, or product and send alerts via Slack, email, or webhooks for cost, latency, and error thresholds.

Manage prompts, models, and workflows in the UI with version control, rollout logic, and integration hooks to promote changes to production.Run online evaluators on sampled production traffic combining automated checks, LLM judges, and human review to measure faithfulness, schema, relevance, and hallucination rates.

Export traces and datasets for experiments, compare prompt/model variants, cache repeat responses to reduce cost and latency, and enforce soft/hard API caps.Use a single gateway to deploy, monitor, and iterate on LLM-powered applications while preserving provider native SDK passthrough when needed.

Key Features
  • Route traffic to models with OpenAI-style API compatibility, provider passthrough, model fallbacks, load balancing, retries/backoff, and per-key spend controls
  • Capture every request as a trace tree with latency spans, metadata, and session context to reproduce and inspect production sessions
  • Monitor usage and performance with dashboards that slice metrics by model, user, key, or product and send alerts via Slack, email, or webhooks for cost, latency, and error thresholds
  • Manage prompts, models, and workflows in a UI with version control, rollout logic, and integration hooks to promote changes to production
  • Run online evaluators on sampled production traffic combining automated checks, LLM judges, and human review to measure faithfulness, schema compliance, relevance, and hallucination rates


Use Cases
  • Route and scale production LLM traffic across 500+ providers using Respan’s OpenAI-compatible gateway, enforcing cost and latency limits, caching frequent responses, and automatically failing over to cheaper or lower-latency models to keep your application fast and affordable
  • Implement full trace-based observability and request tracing for all model calls with Respan’s dashboards and logs, making it easy to monitor latency, error rates, prompt-level usage, and generate SLA/compliance reports for debugging and audits
  • Manage prompts and model experiments using Respan’s prompt/version control and online evaluators to run A/B tests, safely roll out prompt updates, track performance across providers, and auto-select the best-performing model based on live evaluation metrics

Respan AI ile ilgili sürpriz, tercihleri ayarladıktan sonra sürtünmenin azalması oldu. Kısa bir kontrol listem var: hedef kitle, ton, zorunlu maddeler, istenmeyen ifadeler. Bunlarla çıktılar düzenli şekilde kullanılabilir oluyor. Olmadan sonuçlar genel kalıyor. Boş sayfadan başlamak yerine hızlıca iterasyon yapabilmek de büyük artı. Eksik gördüğüm yerler: daha iyi sürüm geçmişi ve net export seçenekleri. Yine de dağınık birkaç aracı elimden aldı. Puanım reklam değil, haftalık pratik faydaya göre.

Impressed with the speed. I tested it on a real project and it held up well.

What surprised me about Respan AI is how little friction there is once you set preferences. I keep a short checklist: audience, tone, must-include points, and forbidden phrases. With that, outputs are consistently usable. Without it, results feel generic. I also like that I can iterate quickly instead of restarting from a blank page. Missing features for me: better version history and clearer export options. Even so, it has replaced a couple of scattered tools in my stack. Rating reflects practical value in my week, not hype from the landing page.

Bad value. Paid upgrade did not fix the core issues — still buggy and inconsistent.

I like Respan AI more than expected. Clean UX and dependable outputs.
