Latitude vs Promptotype

Latitude is an open-source, MIT-licensed platform for monitoring and improving production AI agents. It records agent interactions as spans and groups related traces into sessions for reviewing multi-turn conversations. Observe tools expose model providers, models, tokens, latency, cost, errors, tool calls, user activity, and agent memory. Semantic search, behavior clustering, and signals help locate recurring failures; monitors can watch signals, saved searches, or raw traffic and notify users in-app, by email, or through Slack. Failing traces can become datasets for local simulation and regression testing, while evaluations monitor live traffic for regressions. Latitude offers managed cloud and self-hosted deployment, including Docker Compose and Kubernetes options. Its setup guide names TypeScript and Python SDKs and recommends an OpenTelemetry exporter for other languages. The free Starter plan includes 20K credits per month and 30-day data retention. Pro costs $99.00 per month and includes 100K credits monthly and 90-day retention. Latitude says hosted customer data and managed inference are processed in AWS eu-central-1 in Frankfurt, Germany.

Promptotype is a web-based platform for developing and evaluating structured tasks for language models. Its playground lets users build prompt templates, configure models, and work with function calling. Test queries can include expected JSON schemas or values; a model query can fill in an expected result. Users can run prompts against collections, from smaller development sets to larger checks for production readiness. The platform also provides run and test history, scheduled automated tests with email summaries, and automatic fine-tuned model creation from query collections. A JSON Schema Editor supports schemas compatible with the OpenAI API’s json_schema response_format. The free plan is free. Basic costs $6 a month and adds libraries for templates, configurations, and queries, plus collection testing. Professional costs $10 a month and includes 60 days of history, fine-tuning, and one weekly scheduled run. Team features are contact-based. The maker is Baionic, LLC, which lists a New York, New York mailing address.
