- Added Claude Opus 4.6 model.
- Added GPT-5.3 Codex model.
We revamped the engine running inside each sandbox to be more memory and network efficient when using the dashboard by adding streaming endpoints.
Most notably, we added the ability to run multiple Claude Code or Codex chats.Try it now on the dashboard!
- Slack threads linked to GitHub pull requests now mark messages with a checkmark when the PR is merged.
- Fixed Slack messages not waking sleeping workspaces.
- Repositories are now associated with only one organization. This also means that a
replicas.jsonfile withorganizationIdis no longer needed.
- Fixed wake buttons staying in a pending state when switching between sleeping workspaces.
- Turns for both Codex and Claude Code can be interrupted. Messages that are queued are relayed back.
- Removed GPT Codex Mini from the list of available Codex models as it is not available with ChatGPT/Codex subscriptions.
- Fixed issue where pull requests created by agents were not being tracked in the database.
- Slack mentions now map sender email to git co-author details when available.
- Added user and organization preferences to control whether workspaces close when linked pull requests close or merge.
Workspaces can now be renamed inline. Click the workspace name in the chat header to edit it.
Admins can now change member roles directly from the Members settings page. Promotes members to admin or demotes admins to member, with safeguards against demoting the last admin.
Misc fixes for dashboard QOL:
- Fixed agent chat to have proper scrolling.
- Updated awoken workspaces to properly fetch plan.
Slack integration now supports image attachments. When you mention
@Replicas with an image attached, the agent can now see and process the image.Fixed regression with Claude Code authentication for AWS Bedrock in workspaces.Misc:
- Diff and Plan mode viewers now take up the full main area by hiding the chat input
Added Slack integration for triggering Replicas from Slack channels.
Read the docs!
- Connect Slack workspace via OAuth in organization settings
- Mention
@Replicasin any channel to create a workspace - Interactive dropdown to select repository when multiple are available
- Use
[repo:name]syntax to specify repository inline (inclusive matching) - Agent replies directly in the thread when finished
- Full thread context is passed to the agent for ongoing conversations
- Fixed issue where “Claude is thinking…” would persist indefinitely when using Plan Mode even when done
- Disabled user-input tools (ExitPlanMode, AskUserQuestion) for background agents
Introducing Plan Mode!Plan Mode lets agents explore the codebase and propose a plan before making changes. Plans are shareable and visible in the dashboard, and you can trigger Plan Mode by adding
/plan in GitHub, Linear, or dashboard chat.
Read here!Additional changes:- Linear no longer has a ‘middleman’ agent, instead spawning the workspace immediately.
- Added organization setting to set the default coding agent between Claude and Codex. Try it here here.
- Codex system prompts added by Replicas are inserted to
config.toml, instead of prepending to the message. - Fixed bug where sleep/wake could create multiple active workspace sessions
- Fixed bug where Codex would sometimes fail to trigger from Linear.
Workspaces now start 90% faster than before, thanks to Daytona sandboxes!
As the first major update approaching Replicas V1, we migrated our sandbox infrastructure to Daytona (daytona.io) for sandboxes!
Through our benchmarks, our replica creation -> agent working time went from ~1min to 5 seconds!No changes are required on your end.
- Added GPT-5.2 Codex model support for the Codex agent
- Updated Developer plan pricing from 50/month
- Added support for triggering Replicas tasks from GitHub issue comments (not just PR comments)
- Workspaces can now be created directly from GitHub issues by mentioning
@tryreplicas - When triggered from an issue, Replicas will create a PR and reply to the issue with the PR link and summary
- Issue workspaces are automatically cleaned up when the issue is closed
- Added validation to prevent replica names with spaces in the CLI, MCP, and API
- Fixed CLI build to avoid duplicate shebangs that crashed
replicas loginin Node 20+.
- Added streamable HTTP MCP at
https://api.replicas.dev/v1/mcp - Added stdio MCP client package (
replicas-mcp). - Added CLI commands for replica management:
list,get,create,send,delete,read - Added CLI command for listing repositories:
repos list
- Added a public alpha for the Replicas API. See docs.
- Fixed bug where comments on new PRs would spawn a new replica instead of routing to the original workspace when a replica created multiple PRs on different branches
- Workspaces triggered from GitHub PRs will now automatically receive notifications when CI/CD checks fail. The agent will investigate the failure, fix the issues, and push updates.
- Workspaces triggered from GitHub PRs will now automatically close when the associated PR is closed or merged.
You can now trigger Replicas on any pull request by mentioning
@tryreplicas in a PR comment, even if the PR wasn’t created by Replicas. When triggered, Replicas will:- Verify the repository belongs to your organization
- Create a new workspace to work on the PR
- Checkout the PR branch and address your request
- Automatically associate the workspace with the PR for future interactions
- Hobby: 24 hours
- Developer: 72 hours
- Team: (custom)
- Start hooks now run asynchronously and don’t block the engine from receiving messages
- Start hook outputs are logged to
~/.replicas/startHooks.logfor visibility - Start hooks only run once per workspace lifecycle (persisted across sleep/wake cycles)
- Coding agents are informed when start hooks are running with instructions to check the log
Sending messages to sleeping workspaces will no longer require you to ‘come back’, instead just queueing the message.
Linear Integration Enhancements & Organization Features
- Invite members to organizations for team collaboration
- Coding agents now respect pull request templates in repositories
- Purchase credits directly from the dashboard in flat amounts
- Workspaces now sleep after 1 hour of inactivity and permanently delete after 24 hours
- Messages can queue in the engine while agents are working
replicas.jsonnow supportsstartHookfor running shell scripts on engine startup and customsystemPromptfor agent instructions- Update credentials to connect your own GitHub, Claude Code, and Codex accounts—enables workspaces to use personal credentials instead of organizational defaults
- Fixed bug where Claude and Codex authentication would expire on sleeping workspaces
- Coding agents now accept images in messages
- Dashboard chat supports image uploads
- Linear issues with images in descriptions are automatically passed to agents
- CLI now displays notifications when updates are available
- Fixed issue where CLI connection to workspaces would timeout silently without warnings
- Workspaces that wake from sleep now properly persist thread and branch state
- Organization names can now be edited in settings
The Linear Agent integration is now available! Connect it to your Linear workspace in settings to assign tasks directly to Replicas. When you assign a task, Replicas will automatically spin up a workspace and create a PR for you.
Added GPT-5.1 and GPT-5.1 Codex.
Claude 4.5 Opus and GPT-5.1 Codex Max are now live in Replicas. Switch to the refreshed model selector to try the newest Claude release and OpenAI’s flagship Codex deployment with improved reasoning depth out of the box.
Replicas v0 is officially live! We’re making it easier to spin up production-grade development environments in minutes.GitHub-connected templates
- Connect and authorize your GitHub account once, then build workspace templates straight from your repositories!
- Workspaces inherit your Git credentials automatically, so git operations just work on first boot!
- Chat with Codex directly from the dashboard without opening a terminal!
- Active indicators now surface which workspaces are online! The dashboard is still evolving, and you’ll see rapid improvements over the next few weeks.
- Capture any workspace as a reusable snapshot and boot future workspaces from that image!
- Ideal for large project installs (think
node_modulesor language toolchains) so you only pay the setup cost once.
- Run
replicas codex-authto sync your Codex credentials with Replicas once. All future workspaces inherit that authentication automatically, so you can start chatting immediately.
Updated instance types for better performance:
- Standard: 2vCPU, 4GB RAM @ 2 credits/hour
- Large: 2vCPU, 8GB RAM @ 4 credits/hour
- Power: 4vCPU, 16GB RAM @ 8 credits/hour
We’ve replaced GitHub authentication via personal access token with an official GitHub connection. This lets you automatically scope access to your own repositories.Unfortunately, old templates are no longer viable after this change, and should be replaced.
You can configure your GitHub connection under Connections.
RMI v0.1.2:
- Fixed an issue in the Replicas Machine Image where Docker would not start correctly and block SSH access.
- New
--skip-authflag - Added--skip-authoption toreplicas connectandreplicas codecommands to skip copying Codex authentication to workspaces when not needed
