Open-source LLM eval and red teaming: test prompts, compare models, catch jailbreaks and data leaks locally and in CI.
Best alternatives to Braintrust in 2026
Companies that ship AI products need to know whether the AI's answers are actually good — and catch the bad ones before customers see them. Braintrust is a paid service that records everything your AI does, grades its answers, and can automatically block an update if quality drops: a quality-control lab for AI products. Braintrust is an evaluation and observability platform for teams shipping production AI products. It ingests traces from AI applications — prompts, responses, tool calls — and layers three capabilities on top: tracing for real-time inspection with custom facets and task-specific views, evaluation where outputs are scored by LLM judges, code checks or human reviewers, and automation that turns those scores into quality gates capable of blocking a problematic release before it reaches users. Topics, its AI-powered pattern analysis, surfaces recurring failure modes from production traffic, and traces convert directly into evaluation datasets so regressions found in production become permanent test cases. Telemetry is stored in Brainstore, a proprietary database built for AI-specific data, and framework-agnostic SDKs cover Python, TypeScript, Go, Ruby and C#, with MCP integration. Customers include Vercel, Notion, Coursera, Dropbox, Replit and Graphite. Pricing is usage-based: a free Starter tier, a $249/month Pro plan plus data and scoring volume charges, and enterprise plans with on-premise or hosted deployment.

- ✓ De-facto standard for open-source LLM evals — 23k+ stars, huge community
- ✓ Automated red teaming: injections, jailbreaks, PII leaks, policy violations
Lets you build automations by describing them in plain English instead of dragging boxes around a workflow canvas, then connects them to tools like Slack, Notion or Google Sheets.
- ✓ Construction d'automatisations par description en langage naturel, pas de canvas visuel
- ✓ Agents IA capables de raisonnement et d'autocorrection, pas seulement du if-then
Gives AI agents a real memory and a private workspace so they stop forgetting everything between conversations and re-reading the same documents over and over.
- ✓ Mémoire persistante avec extraction automatique de faits et résolution des contradictions
- ✓ Temps de réponse inférieur à 300ms selon l'éditeur
Lets a company build one AI agent that lives inside Slack, GitHub, Linear and other tools it already uses, instead of juggling separate AI features bolted onto each app.
- ✓ Un seul agent partout au lieu d'IA fragmentées par outil
- ✓ Routage multi-modèles avec failover en cas de panne fournisseur
A privacy-first LLM gateway that routes requests across 600+ models without logging prompts, verified via a Trusted Execution Environment.
- ✓ Cryptographically verifiable no-logging via TEE attestation, not just a policy claim
- ✓ OpenAI-compatible API — easy migration from existing integrations
Turns OpenAPI specs into safe, typed tools that AI agents can call, without manual wiring.
- ✓ Generates typed, ownable code instead of a runtime black box
- ✓ Automatic read/write/destructive risk classification
Open-source enterprise AI platform connecting company knowledge across 50+ apps with permission-aware search.
- ✓ Open source (Apache 2.0), self-hostable — no cloud lock-in
- ✓ 50+ pre-built connectors to enterprise apps
Free, open-source legal AI platform for document review, drafting and legal research.
- ✓ Free and open source (AGPL-3.0) — zero license cost vs. Harvey/Legora
- ✓ Grounded citations link answers back to source documents
A public message board built for AI agents rather than humans — any agent can post a note, request, or result by hitting a URL, with zero setup, no SDK, and no account.
- ✓ Poster ne demande qu'une requête GET, aucun setup
- ✓ Types de messages structurés + salons + flux Atom
An unofficial REST API that lets developers generate Midjourney images from code instead of Discord, with webhooks, polling, and SDKs — since Midjourney itself doesn't offer a public API.
- ✓ Accès API à Midjourney sans passer par Discord
- ✓ Webhooks et polling, SDK Python/Node.js
A policy-bound cloud coding agent that works on isolated, pinned environments and delivers changes as pull requests, with an encrypted audit trail.
- ✓ Politique épinglée par digest, appliquée avant exécution
- ✓ Credentials courtes et scopées, pas de secrets stockés
