bitdrift Labs
bitdrift is an agentic mobile observability platform that logs everything on-device in a ring buffer and uploads only the sessions you care about.
Key features
- On-Device Ring Buffer: A patented local buffer captures unlimited telemetry on the device and only the signals you actually request are ever transmitted, decoupling log volume from cost.
- Remote Workflow Deployment: Change or deploy a new telemetry workflow and data starts flowing immediately — no app redeploy, no app store review cycle.
- bd-skills for Coding Agents: Built on the open agentskills.io standard, bd-skills let Claude Code, Cursor, Codex, and Copilot query live customer-device data while debugging.
- Beyond Crash Reporting: Surfaces ANRs, out-of-memory errors, slow-loading screens, and other non-fatals alongside full crashes, with the relevant context attached.
- 3D Session Replay: Privacy-conscious moment-by-moment replays of the sessions that matter, paired with in-depth logs and synthetic metrics.
- Fleet-Wide Filtering: Zoom from millions of devices down to the single one that matters by filtering on device type, OS version, and behavior.
- Lightweight Multi-Platform SDK: Android, iOS, and React Native SDKs capture rich telemetry with minimal runtime overhead.
- Instant Insights Metrics: Out-of-the-box mobile health, UX, resource, network, and device metrics available without custom instrumentation.
Best for
- Catching Bugs Before Reviews: Mobile teams spot crashes and slow screens in real time rather than learning about them from 1-star app store reviews.
- Cutting Observability Spend: Orgs where observability exceeds 30% of infrastructure cost move to paying for used data instead of generated data.
- Debugging Without a Release: Engineers add the telemetry they wish they had mid-incident by deploying a workflow, without waiting for the next app version.
- Agent-Assisted Bug Fixing: Coding agents pull real device sessions through bd-skills so fixes are grounded in actual user behavior.
- Diagnosing Non-Fatal Degradation: Track ANRs, memory pressure, and battery drain that never produce a crash report but still drive churn.
- Reproducing Elusive User Reports: Session replay plus the session timeline reconstructs exactly what a specific user saw around an issue.
Switchyard
NVIDIA
An open-source Rust proxy and library that routes LLM traffic across models and providers while preserving native OpenAI and Anthropic API compatibility.
Key features
- Protocol Translation: Converts between OpenAI Chat Completions, OpenAI Responses and Anthropic Messages formats so clients keep their native API while any backend serves the request.
- Multi-Backend Routing: Spreads traffic across vLLM, NVIDIA NIM, Ollama and any OpenAI-compatible endpoint, letting you point an existing coding agent at an open-source model without changing the agent.
- LLM Classifier Router: Uses request content to decide whether a given turn needs the weak or the strong model tier, cutting spend on turns that do not need frontier capability.
- Stage Router: Routes most turns from signals already in the conversation — tool results, errors, conversation stage — so no extra model call is needed to make the decision.
- Escalation Router: Runs every turn on the weak tier first, then has a judge read that answer and decide whether the same request should be re-sent to the strong tier.
- Random Routing for A/B Tests: Applies a fixed traffic split across targets for benchmarking, baselines and cost experiments.
- Operational Metrics: Exposes Prometheus metrics for requests, errors, latency, token counts and the overhead added by routing itself.
- Server or Library Deployment: Run it as a standalone Rust proxy configured by routes.toml, or embed switchyard-libsy in your own application so it decides the target and hands the model call back to you.
Best for
- Pointing Coding Agents at Open Models: Serve Claude Code or Codex from vLLM, NIM or Ollama without the agent knowing the API changed.
- Cost/Performance Optimization: Send routine turns to a cheap weak-tier model and reserve the strong tier for turns a classifier or judge says need it.
- Model A/B Benchmarking: Split traffic on a fixed ratio across two models to compare quality, latency and cost on real production requests.
- Provider Migration and Failover: Keep application code on one API shape while swapping or mixing the providers behind it.
- Embedding Routing in an Agent Runtime: Drop the routing algorithms into an existing gateway or agent framework via the library path without adopting a new HTTP stack.
- Operational Visibility: Track per-route latency, error rates and token spend through Prometheus to find which routes are actually costing money.
