Braintrust Alternative: Adaline vs. Braintrust for End-to-End LLM Development

A comprehensive comparison of collaboration, deployment capabilities, and prompt lifecycle management to help you choose the best platform for shipping production AI in 2026.

Braintrust and Adaline both support llm evaluation and observability, but they differ in how they cover the broader AI development lifecycle and enable cross-team collaboration.

Braintrust is evaluation-first, optimized for systematic testing and CI/CD integration. It’s strong at running eval suites, turning production traces into test datasets, and using GitHub Actions to automate checks. The workflow is largely engineer-led, with code-first evaluation pipelines driving iteration.

Adaline is a collaborative platform that covers the full prompt lifecycle: iteration, evaluation, deployment, and monitoring. Product managers can iterate on prompts without depending on engineering teams. Prompts ship like code, with version control, staging environments, and instant rollback. Teams collaborate in a single workspace rather than passing work back and forth across multiple tools. Evaluations run continuously, but they’re part of a broader workflow that treats prompts as deployable artifacts.

The core difference: Braintrust tells you whether prompts pass tests. Adaline tells you whether prompts pass tests, enables non-engineers to iterate on improvements, and deploys those improvements with production-grade safeguards—all in one collaborative platform.

Braintrust

Braintrust is an AI evaluation and observability platform centered on systematic testing. It offers robust evaluation frameworks with built-in CI/CD support, helping teams catch regressions before they hit production by running automated checks on every pull request.

Application

  • Evaluation-first approach: Structured testing using datasets, tasks, and scorer frameworks.
  • Built-in CI/CD workflows: GitHub Actions that execute evals and report results on pull requests.
  • Brainstore observability: Production logging tailored for AI traces with fast query performance.
  • Code-first operation: Engineers build evaluation pipelines via the SDK.
  • Loop AI assistant: Tools for prompt optimization and dataset generation.
  • Best for: Engineering-led teams that prioritize evaluation rigor and CI/CD integration.

Important Note

Braintrust is strong on evaluation and CI/CD, but most workflows still require engineering involvement. Product managers may prototype in a basic playground, then engineers implement the evaluation pipelines and connect them to deployment. Prompt deployment, version control, and staging workflows are typically handled outside the platform and require custom engineering.

  • Best for: Product and engineering teams that need the entire prompt lifecycle managed collaboratively.

Important Note

Companies that treat prompts like deployable code and want non-engineers actively contributing without creating engineering bottlenecks. Organizations where iteration speed matters as much as evaluation rigor.

Core Feature Comparison

Workflow comparison

Braintrust workflow for improving a prompt:

  • An engineer writes evaluation code defining the dataset, task, and scorers.
  • Run evals programmatically using the SDK or trigger GitHub Action.
  • Review results with the PM and provide feedback to engineering.
  • Engineer updates prompt in codebase based on feedback.
  • Engineer reruns evals to verify improvement metrics.
  • Engineer deploys through the standard CI/CD pipeline outside the platform.
  • Monitor with Brainstore, and manually create new test cases from production failures.

Adaline workflow for improving a prompt:

  • PM identifies the issue in the production traces dashboard.
  • PM adds problematic traces to the evaluation dataset with a single click.
  • PM iterates on prompt fix in Playground, seeing live eval results.
  • PM validates improvement across all test cases immediately.
  • Engineer reviews changes and promotes tothe Staging environment.
  • Automated evaluations run on staging with pass/fail gates.
  • Promote to Production with instant rollback option, continuous monitoring, and automatic.

The practical difference: Adaline eliminates engineering dependencies for prompt iteration. What requires engineering cycles for every prompt change in Braintrust happens independently in Adaline, with engineers maintaining deployment control but not blocking iteration velocity.

Collaboration and Iteration Speed

How Braintrust handles product-engineering collaboration:

Engineers own evaluation pipeline creation. Product managers prototype in the playground but cannot independently run comprehensive evaluations. Each iteration requires engineering to build evaluation code, run tests, and interpret results. Deployment is handled by external CI/CD. PM velocity is gated by engineering availability.

How Adaline handles product-engineering collaboration:

Product managers independently iterate with full evaluation access. They upload datasets, run evaluations, and see quality metrics without engineering. Engineers pull production-ready code from PM experiments, maintaining deployment control. Both roles work in one workspace with shared visibility. PMs validate improvements autonomously, engineers govern releases.

Deployment and Production Safety

Braintrust approach:

Evaluation results inform deployment decisions but actual deployment happens through external CI/CD. Teams build custom prompt version control, staging environments, and rollback mechanisms. Feature flags require separate tooling. Rolling back requires reverting code and redeploying. The platform shows whether changes pass quality gates, but deployment infrastructure is external.

Adaline approach:

Prompts are treated as deployable artifacts with full lifecycle management. Version control with commit messages and diffs. Dedicated dev, staging, and production environments with promotion workflows. Instant one-click rollback. Built-in feature flags for controlled rollouts. Evaluation gates integrate with deployment to automatically prevent bad prompts. Complete audit trails built-in.

Evaluation Capabilities

Braintrust evaluation strengths:

Datasets, tasks, scorers framework is well-architected. AutoEvals library provides comprehensive evaluators. GitHub Actions integration is best-in-class. Brainstore optimized for querying millions of traces. Loop generates datasets, optimizes prompts, creates scorers automatically. Engineering teams get powerful evaluation pipeline tools.

Adaline evaluation strengths:

Built-in evaluators: LLM-judge, text similarity, regex, custom JavaScript/Python. Dataset upload accepts CSV/JSON plus AI-assisted generation. Continuous evaluation on live traffic with drift detection. Pass/fail gates integrate with deployment. One-click eval case creation from production failures. Analytics show quality trends over time. Product managers access same power as engineers.

Evaluation results from testing 40 user queries on a custom LLM-as-Judge rubric.

Both platforms offer strong evaluation. The difference is integration: Braintrust evaluation feeds external deployment. Adaline evaluation controls integrated deployment with automated gates.
