Best alternatives to promptfoo in 2026
When companies build apps on top of AI models — chatbots, assistants, support tools — they need to check that the AI answers correctly and cannot be tricked into revealing or saying things it shouldn't. promptfoo is a free tool that runs those checks automatically: part spell-checker, part security guard for AI applications. promptfoo is an open-source platform for testing and securing LLM applications. Its evaluation side lets developers define test cases for prompts, agents and RAG pipelines, then compare outputs side by side across providers — OpenAI, Anthropic, Azure, Bedrock, Ollama and others — from a CLI or a local web UI with live reload. Its security side automates red teaming: generated attacks probe for prompt injections, jailbreaks, PII leaks and business-rule violations, and real-time guardrails plus an MCP proxy defend agent traffic in production. Everything runs locally by design — prompts never leave the machine during evaluation — and the same checks wire into CI/CD so regressions and vulnerabilities block a pull request instead of reaching users. The project is MIT-licensed TypeScript with over 23,000 GitHub stars and a 300k+ user community feeding its threat intelligence. promptfoo was acquired by OpenAI in March 2026 but remains open source and independently maintained, with an enterprise tier for larger teams.

- ✓ Trace-to-dataset loop: production failures become permanent eval cases
- ✓ Quality gates block bad AI releases like CI blocks bad code
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
