react-scan by @aidenybai is amazing

lowkey proud of the fact that the experiments feature in @helicone_ai is very performant - not making the whole table rerender was something we actively made sure of when building it. the extension is giving some really good insights

I joined Y Combinator with 14 users, building a dev tool for myself.

Then @SaaiArora joined as CTO, and we started growing and shipping 2x faster. It forced us to rebuild product and infra from the ground up for teams, not solo devs.

We are ending the batch with >300k agent minutes per week, and teams like @mintlify, @knowunity, and @modaflows shipping through Replicas every day.

Today we're launching Replicas V2.

Introducing Custom Environments - unlimited use cases for background agents.

With each custom environment, you can configure it with system prompts, skills, MCPs, and dependencies/tooling tailored for the job.

For example:
- a Debugging environment that has access to Cloudwatch logs and our traces
- a Data Analyst that has Postgres & Snowflake
- a Marketing environment instructed to read X and LinkedIn posts
- a ML environment with access to an H100 and datasets
- a Sales environment with access to HubSpot or Salesforce

Our customers are already automating engineering - E2E tests with specific prompts and access to latency metrics, adjusting classifiers,

With 3 sentences and a click, Replicas sent this to me on Slack:

@maxleiter @shuding @shadcn @jaredpalmer @gaspargarcia_ @v0 was an honor getting to work with you max, you will be missed 🫡🐐

@newdotwebsite has been acquired by Vercel! ▲

We built a way to turn a simple description into a fully functional site in minutes, with forms, automations and integrations that work agentically out of the box. Now we’re joining @v0 to take it further.

This wouldn’t have happened without our team and the people who believed in us early. Grateful to @vercel for taking a chance on what comes next.

We simplified how v0 organizes your work.

• Folders: group related chats together.
• Projects: connected to your actual app, with code, environment variables, deployment, and git.

Start a chat in a Project and your infrastructure is already loaded.

Introducing the new Replicas Dashboard!
- Launch workspaces
- Chat with CC or Codex (with your subscription)
- View changes using our diff viewer

And unlike CC or Codex on Web:
- SSH access
- Snapshots, to customize the agent's local dev environment

@ashverm4 yaaa the amount of times i tone down talking about Exun thinking about how crazy it would sound because it was "just a club"
