Every tool call. Every decision. Every data access. Cryptographically hashed into a tamper-proof chain. Compliance-grade. Three lines of code.
# Before: zero visibility
agent.run("Process this invoice")
# After: full audit trail
with opswald.trace():
agent.run("Process this invoice")
# ✓ Every tool call recorded
# ✓ Every LLM request captured
# ✓ SHA-256 hash chain verifiedAgents call tools, access databases, make decisions, modify files. When something goes wrong, you can't reconstruct what happened.
Your agent made 47 tool calls, accessed 3 databases, and modified 12 files. Can you reconstruct the exact sequence? With current tools: no.
LangSmith, Langfuse, and Helicone track traces for debugging. But their storage is mutable, has no cryptographic integrity, and would not hold up in a regulatory audit.
High-risk AI systems must maintain automatic logging for traceability and post-market surveillance. Compliance deadlines start in 2026. Is your agent infrastructure ready?
Instrument your agents in seconds. Get compliance-grade audit trails forever.
Any framework. Any LLM.

3 lines of code. Captures every action, tool call, MCP interaction, and decision.
→SHA-256 append-only ledger. Tamper with one event = entire chain breaks.
→Instant answers: "What did agent X do on Tuesday?" One-click EU AI Act reports.
When an incident happens, Opswald gives you the proof.
Engineering Lead
"Which agent accessed customer PII last month?"
Opswald indexes every data access event. Query by agent, time range, data type. Get results in milliseconds with cryptographic proof.
CISO
"Can you prove this agent didn't modify that record?"
Every event is SHA-256 hashed into an append-only chain. Verification is instant. If a log was tampered with, you'll know.
Compliance Officer
"Are we Article 12 compliant for our AI systems?"
One-click EU AI Act compliance report. Automatic logging, traceability, and monitoring — exactly what regulators require.
Developer
"My agent failed — what happened in the last 50 steps?"
Full execution replay with every tool call, input/output, and decision. Debug production agent issues in minutes, not days.
Existing tools were built for debugging. Opswald was built for proof.
