April 2026: Delivered core sandbox networking enhancements and multi-language desktop automation capabilities, focusing on restoring public sandbox access, robust tunneling, and reliable remote desktop automation across Python, TypeScript, and JavaScript SDKs. Key deliverables include restoring unauthenticated access for sandbox ports, introducing the tl sbx tunnel (WebSocket-based TCP relay), hardening SSH session handling, and delivering Rust-backed desktop automation accessible via Python, Node.js, and TS SDKs, underpinned by comprehensive tests and end-to-end validation.

March 2026: Delivered substantial Sandbox CLI and testing improvements in Tensorlake. Key features include Sandbox CLI Management and UX enhancements (snapshot listing, improved timestamp formatting, real-time streaming for sbx exec/run, and full lifecycle controls: suspend, resume, terminate, delete). Implemented CLI workflow refinements (tl sbx new --no-wait) to clarify behavior and reduce confusion. SSH access handling was adjusted with changes to default sandbox resources and a raised memory minimum to 2GB, aligning compute allocations with typical workloads. Sandbox Dataplane Testing Configuration was updated to include a snapshot directory to stabilize stateful tests and a version bump to 0.4.26. Together, these changes improve developer productivity, operational reliability, and cost-aware lifecycle management.

February 2026 monthly summary for tensorlakeai/indexify: Focus on stability and reliability of Firecracker startup. Implemented a critical fix for resolv.conf handling when it is a symlink, ensuring accurate DNS configuration without interference from previous symlink state. This change reduces boot-time DNS errors and supports dependable container initialization in downstream services.
