Crewe manager Steve Davis admitted his side's lack of a killer punch cost them the chance of three points against Carlisle.
Ajay Leitch-Smith went closest for Alex with a 70th-minute snapshot which shook the crossbar.
Davis said: "We more than deserved the draw and could even have won the game because we had several clear openings in the first half when I felt we were the better team.
"They came into it a bit, but we defended the crosses well. We had more opportunities and hit the bar, but we were a bit shot shy even if it was not for want of trying.
"It was a decent game and with a bit more fortune we would have done. We played some good football and I was proud of a good performance. Our movement was good and it was just the final ball in the last third and the killer edge in front of goal we lacked.
"Carlisle have been in this league a long team and we are just adapting. We are getting belief and resilience and I am more than pleased with the players' efforts."
