Open-source AI gateway and LLM observability: one API for 100+ models, cost and latency tracking, prompt management.
Best alternatives to BaseRun in 2026
Building a feature powered by a large language model comes with a debugging problem traditional software doesn't have: the same prompt can produce different outputs, failures are often silent (a bad answer, not a crash), and it's hard to know what changed when quality suddenly drops. BaseRun is built to give AI teams the equivalent of application monitoring, but for LLM behavior specifically — tracing what happened in a given AI interaction, catching errors, and watching quality metrics over time in production. Technically, it provides LLM execution tracing and debugging, error tracking and diagnostics specific to AI failure modes, performance monitoring and analytics, integrations with popular LLM frameworks, and a real-time observability dashboard for production AI systems. It offers a free tier for development and testing, with paid production plans priced by trace/request volume. BaseRun is a Y Combinator-backed company (S23 batch) operating in the fast-growing LLMOps space, alongside better-known names like LangSmith, Helicone, and Braintrust.

- ✓ One-line integration via proxy — instant cost/latency visibility
- ✓ Gateway + observability in one: routing, fallbacks, one key for 100+ models
AI eval and observability platform: tracing, LLM and human scoring, quality gates. Used by Vercel, Notion and Replit.
- ✓ 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
