Let agents compete. Promote the winner.
Spin up parallel clones from the same snapshot. Let multiple agents race on isolated sandboxes. Compare results side by side. Promote the best outcome to production.

Define the task
Describe what you need: a migration, a data cleanup, a schema refactor. Guepard spins up N parallel clones from the same production snapshot.
Agents compete in parallel
Each agent gets its own isolated sandbox. They run their approach simultaneously. Different strategies, same real data, zero interference.
Compare & promote
Review the results side by side. Pick the best outcome. Promote the winning branch to production, or discard everything with no trace.
The shift
Safe experiments, not dangerous guesses
Seed files & mocks
Agents hallucinate on fake data that drifts from reality
Shared dev databases
One bad migration and every agent is down
No rollback
Agent makes a mistake? Good luck reverting manually
One agent at a time
Sequential experiments block your pipeline
Real production data
Every agent works on an exact clone of prod. Zero drift
Isolated sandboxes
Each agent gets its own environment. Full isolation
Instant rollback
Discard the clone. Production is untouched. Try again
Parallel experiments
N agents race on N clones from the same snapshot
Capabilities
Everything agents need to experiment safely
Isolated sandboxes. Parallel execution. Instant rollback. MCP integration.
Isolated sandboxes
Every agent gets its own clone. Full compute and storage isolation. Zero cross-contamination.
Parallel experiments
N agents, N clones, same snapshot. Race strategies simultaneously. Compare outcomes side by side.
Rollback on failure
Agent broke something? Discard the clone instantly. Production is untouched. Try a different approach.
Compare & promote
Review results from every agent. Promote the winning branch to production. Discard the rest.
Use cases
Let agents solve your hardest data problems
Safe Migrations
Agents test every schema migration on an isolated clone. If anything breaks, rollback instantly. Merge to production only when green.
Data Cleaning
Let agents deduplicate, standardize, and enrich data on an exact copy of production. Validate results before promoting to the real thing.
Backfills
Run large backfill operations on a clone first. Verify correctness, measure performance, then replay the operation on production with confidence.
Code Verification
Agents that write code verify their queries and ORM changes against real data. Not fixtures that lie about edge cases.
Why Guepard
Traditional cloning vs. Guepard
Setup
Add Guepard to your agent in 60 seconds
Paste the config into your agent's settings. That's it. Your agent immediately gets access to 20+ MCP tools: fork databases, run queries, apply migrations, rollback mistakes.
