Latitude vs PromptForge

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.

PromptForge is a web and API platform for building, testing and deploying multimodal prompts. Its workbench includes chat, image and video, speech, transcription and embeddings modes, with a model catalog, streaming previews and version history. Teams can batch-test prompts on datasets using evaluators, A/B tests and scheduled regression runs. Release gates enforce a configured pass-rate threshold through the app, APIs or CLI tools, including GitHub Actions. Versioned deployments offer environment pins, invoke URLs, optional schedule guards and API keys. A visual builder links prompt steps, HTTP calls and logic into versioned flows. Production and test logs provide cost, latency and quality signals. The media library stores uploaded and generated images, video and audio with metadata, bulk actions and links to prompts. BYOK connections support providers including OpenAI, Anthropic and Google. The free plan is free for one user, three projects, 200 test runs monthly and 1 GB storage.
