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.

#1
- ✓ Trace-to-dataset loop: production failures become permanent eval cases
- ✓ Quality gates block bad AI releases like CI blocks bad code
#4
An AI assistant for therapists that listens to a session (in person or on a video call), transcribes it, and writes the clinical note afterward so the therapist doesn't have to.
kith.space
- ✓ Ambient transcription frees the therapist to focus on the client
- ✓ Automated SOAP notes cut post-session admin time
#5
A shared memory service for AI assistants and agents — it remembers facts and context from your conversations across tools like Claude, ChatGPT, and Cursor, instead of each tool starting from zero every time.
itsuki.app
- ✓ Shares memory across many AI tools instead of siloing it per-app
- ✓ Structured, source-linked memories with real audit trail
#6
Managed hosting for persistent AI agent bots — isolated runtime, memory, missions, and integrations (GitHub, Slack, Sentry, MCP) so you can hire an AI worker instead of running your own agent infrastructure.
deploy-hermes.com
- ✓ No server or infrastructure setup required to run persistent AI agents
- ✓ Workspace-level approval and credential controls limit blast radius of autonomous actions
#7
AI agent that resolves support tickets automatically on top of Zendesk, Freshdesk, Salesforce or HubSpot, building its own knowledge base and escalating tricky cases to humans, billed per resolution instead of per seat.
useify.ai
- ✓ Layers on top of Zendesk, Freshdesk, Salesforce or HubSpot without forcing a helpdesk migration
- ✓ Per-resolution pricing avoids paying for idle seats or unused agent licenses
#8
A knowledge-graph memory layer that gives AI coding agents persistent, factual context about your codebase, tickets, and docs — without another hosted service.
oynix.dev
- ✓ Real knowledge graph of ownership and dependencies, not just vector search
- ✓ Self-hosted, data in your own database — no mandatory hosted service
#9
A local-first AI assistant that runs entirely on your machine, remembers context across apps and devices, and only acts with your explicit approval.
github.com
- ✓ Runs entirely on your own machine — no data sent to a third party by default
- ✓ Multi-layer memory (working context, episodic, semantic graph, execution history)
#10
A local-first debugging tool that visualizes what's happening inside an AI model — attention, features, and agent steps — without cloud infrastructure.
github.com
- ✓ Covers language models, VLMs, and robot policies in one tool
- ✓ Attention visualization, SAE feature exploration, and agent-step tracing combined
#11
An open-source agentic RAG system that searches 12 biomedical databases and produces a source-cited synthesis of the evidence.
github.com
- ✓ Searches 12 biomedical databases plus citation networks
- ✓ Citation verification step specifically prevents hallucinated references
#12
An open-source, self-hostable platform for coordinating multiple AI agents across Slack, Discord, GitHub, and other tools in shared conversations.
github.com
- ✓ Coordinates multiple AI agents across Slack, Discord, GitHub, GitLab, Telegram, Lark
- ✓ Provider-agnostic — works with Claude, OpenAI, Grok, DeepSeek, and more
