Project mention: 6 Agent Gateway Platforms That Actually Exist in 2026 (And What They're Good For) | dev.to | 2026-05-04
Quick mental model: an agent gateway is the load-bearing wall between your agents and the rest of your infra. LLM routing, MCP tool governance, agent registry, A2A traffic, audit logs. Same energy as Istio or Kong, just pointed at agents instead of microservices.

consul
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Project mention: Why We Replaced Whisper 2.0 with Deepgram 2.0 and Cut Voice Transcription Costs by 45% | dev.to | 2026-04-28Never perform a big-bang migration when moving critical infrastructure like ASR. We used HashiCorp Consul (https://github.com/hashicorp/consul) for feature flags to route 5% of traffic to Deepgram initially, increasing by 10% daily over 10 days. We also implemented circuit breakers for both services: if Deepgram's error rate exceeded 1% over a 5-minute window, traffic automatically fell back to Whisper with zero user impact. This approach caught a Deepgram API outage in the eu-central-1 region on day 3 of the migration, which only affected 5% of traffic and was mitigated automatically. We also emitted Prometheus metrics for every request, tracking latency, error rate, and cost per request, which allowed us to roll back the entire migration in under 30 seconds if needed. Gradual shifting also let us identify a Deepgram bug with Arabic diarization that only occurred on 0.2% of our traffic, which we reported to Deepgram and was patched in 48 hours. Feature flags are table stakes for any infrastructure migration – if you don't have a feature flagging system, use a simple environment variable to start, as shown below:
