Braintrust vs Tigris
Side-by-side trajectory, velocity, and editorial themes.
Braintrust is making LLM observability painless to adopt — auto-instrumentation across every major language.
Braintrust's recent run is dominated by zero-code instrumentation work: Python, Ruby, Go, and TypeScript all gained auto-instrumentation, and topics automatically classify logs without manual schema work. The product is also deepening agent-tooling integrations with Claude Code and Temporal, and adding operational features like trace translation, member session history, and dataset tagging. Monthly SDK releases continue with steady model-coverage updates.
The trajectory is unambiguous: Braintrust is making LLM evals and observability frictionless to start with — drop a SDK, get traces — and then deeper to live in for engineers running multi-step agents. Auto-instrumentation across four languages plus structured topic-classification of logs lowers the start-up cost. The Claude Code and Temporal integrations show Braintrust is positioning to observe long-running agentic workflows specifically, not just one-shot chat completions.
Expect more agent-framework integrations (LangGraph, CrewAI, OpenAI Agents SDK if not already covered) and richer agent-aware UI — span trees that group reasoning steps, replay-from-step, automatic eval generation from production traces. The member-activity work hints at SOC 2/enterprise compliance pressure that will shape additional governance features.
Tigris turns its object store into agent infrastructure with Agent Kit, agent-shell, and durable global streams.
Tigris's release stream is a sustained product-marketing push around AI-agent storage primitives. Agent Kit landed as a TypeScript SDK exposing bucket forks, workspaces, checkpoints, and event coordination. agent-shell put a virtual bash environment with persistent storage in front of those primitives. Durable global streams via S2 Lite extended the object store into a streaming substrate suitable for per-agent reasoning traces. Around the launches, case studies and tutorials (Basic Memory, the $10 self-updating knowledge base) make the pitch concrete.
Tigris is staking a position that the right substrate for AI agents is not a database, vector store, or queue — it is a globally-distributed, fork-able object store. Each blog and SDK in this batch reinforces that thesis from a different angle: storage as message queue, fork-per-agent sandboxing, storage-protected agent containment, streams for reasoning traces. The competitive map being drawn includes R2, S3 Express, Backblaze, and the agent-runtime vendors (Modal, E2B), not other databases.
Expect a managed Vector or Lance-index surface on top of buckets to compete more directly with Turbopuffer and Pinecone, and a Python counterpart to the @tigrisdata/agent-shell TypeScript runtime to widen the agent-developer surface area.
